Subject: Hydrological applications of EOS-04 synthetic aperture radar
Keywords: Bathymetry, EOS-04, flood, hydrology, synthetic aperture radar, water level
Abstract: Synthetic aperture radars (SARs) have enabled all weather sensing of land surfaces, which has significantly
benefitted surface hydrology. In this article, we explore
various hydrological applications enabled by Indian
Space Research Organisation’s (ISRO’s) recently launched Earth observation satellite-04 (EOS-04) C-band
SAR satellite. We present the preliminary results of
EOS-04 driven flood inundation mapping, monitoring
of water bodies and study of river dynamics. Novel application of EOS-04 SAR data in estimation of sedimentation
rate is presented for Jayakwadi reservoir, Maharashtra,
India. Additionally, this article explores the integrated
use of SAR and altimeter data for estimation of lake and
reservoir water level and volume. We have used multidate observations from EOS-04 SAR and Sentinel-3A/
3B altimeters to derive river width and estimate area–
water level hypsometric curves for reservoirs. Long-term
and near real-time availability of EOS-04 data can
provide an indispensable tool for monitoring water bodies
and extreme events like floods, at regional scales

Subject: Operational 500 m surface soil moisture product using EOS-04 C-band SAR over Indian agricultural croplands
Keywords: Active-passive, agricultural applications, EOS-04 SAR, soil moisture active and passive, surface soil moisture
Abstract: Surface soil moisture (SSM) at high spatial resolution is
an essential land parameter for agricultural applications like irrigation mapping, scheduling, crop water
stress assessment, etc. However, available satellite derived soil moisture products are inadequate for meeting
the requirements of agricultural applications due to
coarse scale soil moisture (~10–40 km). In this article,
we developed an operational framework for first of its
kind sub-km (~500 m) operational soil moisture product
over India by utilizing ISRO’s EOS-04 C-band synthetic
aperture radar (SAR) data based on active-passive approach. The potential of EOS-04 SAR for sub-km scale
is demonstrated and tested over major cropland sites
covering highly heterogeneous and dynamic crop conditions in different agro-climatic regions over India which
shows a good agreement with in situ datasets with mean
ubRMSE, ranging from 0.051 to 0.078 m3

Subject: Inventory and mapping of kharif crops using machine learning with EOS-04 time-series SAR data
Keywords: C-band SAR, crop discrimination, EOS-04, kharif season, random forest.
Abstract: Efficient discrimination of diverse kharif crops, remains
crucial for crop monitoring and production forecasting, and plays a pivotal role in decision-making for
food security in India. This study aims to harness temporal backscatter data from EOS-04 C-band synthetic
aperture data (SAR) payload to achieve precise discrimination among six short-duration (cereal, oilseeds,
fibre) and long-duration (fibre, pulses) kharif crops.
The study integrates limited ground-truth polygons
and a Random Forest machine learning approach for
analysing EOS-04 time-series data. The classification
accuracies were found to be higher than 75% across all
kharif crops, with cereals exhibiting the highest accuracy, succeeded by fibre, oilseed and pulse crops. A
key focus lies in identifying optimal polarization combinations for effective discrimination among diverse
kharif crop types. The study reveals that the synergistic
utilization of dual polarizations outperforms individual
co- or cross-polarizations, notably benefiting discrimination of cotton, soybean and groundnut crops. Horizontal–vertical polarizations are found to be most
effective for achieving peak accuracies in rice and red
gram crops. Furthermore, the analysis indicates a
promising potential for early crop assessment, presenting an opportunity to furnish precise crop estimates at
least one and a half months before the harvest.

Keywords: Backscatter, EOS-04 (RISAT-1A), MIDAS, polarimetry
Abstract: Earth observation satellite-04 or EOS-04 (Radar imaging
satellite-1A or RISAT-1A) provides the opportunity
for characterization of surface features using C-band
fully-polarimetric, hybrid-polarimetric and dual-polarimetric radar data from same platform in high to moderate resolution (2–50 m depending on mode) and varied
incidence angle (12°–55°). These unique EOS-04 radar
datasets can be processed using Microwave Data Analysis
Software (MIDAS) tool, to derive radar polarimetric
parameters. MIDAS is capable of carrying out synthetic
aperture radar (SAR) data processing comprising radiometric and majority of the polarimetric processing of
EOS-04 datasets. In addition, MIDAS has the functionality to orthorectify and geocode EOS-04 polarimetric
products, which is missing in other softwares. Further,
MIDAS contains module for bulk-processing of timeseries EOS-04 products. We showcase results obtained
from EOS-04 datasets and describe the scattering
behaviour of various targets. Further, we also demonstrate the temporal variation in the backscatter values
from different target features obtained from EOS-04
time-series stack, which has strong applicability in land
use/land cover and agricultural applications. Thus, the
radiometric and polarimetric products can be highly
beneficial for characterization of physical properties of
the scatterers based on their radar scattering behaviour and further classification of the surface features.

mission of India’s first indigenously developed spaceborne C-band synthetic aperture radar (SAR) on-board
RISAT-1 satellite. This article provides a description
of the post-launch calibration and data quality evaluation of EOS-04 launched on 14 February 2022. Calibration devices (corner reflectors) of different shapes
and sizes were deployed at Ahmedabad and Amrapur
calibration sites in Gujarat, India from 2 to 24 April
2022, and their response in the EOS-04 data was used
to assess the radiometric and polarimetric calibration.
The results of the analysis showed satisfactory radiometric and polarimetric data quality. Geolocation accuracy was assessed using the ground-surveyed position
of the corner reflectors and was found to be in accordance with the specified values of less than 50 m.

Abstract: EOS-04 (Earth Observation Satellite-04), launched on
14 February 2022, is a follow-on mission to Indian
Space Research Organisation’s first synthetic aperture
radar (SAR) satellite RISAT-1. It is capable of imaging
in either side of the track with incidence angle range
from 12.2° to 55.1°. Onboard SAR system supports
variety of resolution and swath requirements and can
operate in various modes like StripMap, ScanSAR and
Sliding Spotlight modes with various polarization
combinations like linear, hybrid and full/quad polarimetry. EOS-04 is the first spaceborne SAR mission
worldwide supporting full-polarimetry (FP) data acquisitions in ScanSAR modes. Availability of FP datasets in
wide swath modes (ScanSAR modes) is a big step towards
scientific analysis for various applications in a timebound manner. For enabling interferometric processing,
EOS-04 orbits are being maintained within the baseline
requirements of 500 m. EOS-04 has 17 days repetivity
resulting in less temporal decorrelation to use the datasets for various deformation studies. In addition to this,
analysis ready data (ARD) product, normalized radar
backscatter (NRB) Gamma0 product, are introduced
to minimize the user efforts for any immediate analysis.
In NRB Gamma0 products, terrain induced variations
particularly on hill-slopes affecting the brightness of
the radar return is normalized by applying radiometric
terrain correction (RTC) on SAR images. This paper
discusses about the data processing aspects related to
calibration, polarimetry, interferometry and NRB
Gamma0 product generation.

Abstract: The C-band Synthetic Aperture Radar (SAR) payload
of Earth Observation Satellite (EOS-04), is a follow-on
mission of Radar Imaging Satellite (RISAT-1). Though
the overall configuration of the C-Band SAR payload
has been retained from its predecessor, EOS-04 boasts
of incorporating features, which target to keep up with
the technological strides, and to improve the data quality.
All the major modes of RISAT-1 are retained in EOS04 whereas fine resolution stripmap-2 mode, which
was quad-polarization mode earlier, is upgraded to
full-polarization mode. The payload also has better repeat cycle with improved systematic coverage mode.
This article covers system level advancements, and radio
frequency and digital electronics hardware, implemented in EOS-04. The satellite was launched on 14 February 2022 and since then all the major imaging modes
are being operated successfully.

Subject: Modelling flow through petroleum reservoirs: different from saturated groundwater flow?
Keywords: Darcy’s law, groundwater flow, Navier–Stokes equation, petroleum reservoir, representative elementary volume
Abstract: The present article highlights a few fundamental aspects that need to be considered while characterizing fluid flow through a petroleum reservoir. Darcy’s law, as applied in describing fluid flow
through pipes or saturated groundwater aquifers, cannot be directly applied under all circumstances.
Darcy’s original version of Darcy’s law carries a simple algebraic equation relating linear Darcy
flux with the hydraulic gradient. Steady-state Darcy’s law is being applied with lots of assumptions,
even when describing saturated groundwater fluid flow. However, fluid flow through a petroleum
reservoir involves multi-dimensional, multi-phase and multi-component, compressible fluid flow with
inertial effects under non-isothermal conditions. This article highlights first why already established
Navier–Stokes Equation cannot be applied to characterize fluid flow through a petroleum reservoir;
and then shows why the fundamental principle associated, even with fluid flow through a saturated
groundwater aquifer, cannot be applied directly to characterize the flow through a petroleum reservoir. Finally, the article presents critical limitations associated with mass conservation equation,
momentum conservation equation and fluid flow equation used to characterize flow through petroleum
reservoirs.

food in several Latin America and African
countries, including several parts of Asia,
and provides sustenance to millions. Maize
is the principal energy source in poultry
diets across the globe, including India, because of its high-energy value, palatability,
presence of pigments and essential fatty
acids. In a nutshell, it is the only cereal crop
used for both human nutrition and livestock feed1
. It is not just any ordinary
cereal but a nutri-cereal – a term used to
describe cereals that are rich in nutrients
and have numerous health benefits2
. Further, it is the only cereal of many types
(field corn, quality protein maize (QPM),
baby corn, sweet corn, popcorn, waxy corn
and few others). It serves several purposes,
namely, to meet the nutritional requirements of humans as food, livestock and
cattle as feed and raw material for numerous industries.

Keywords: None
Abstract: Buffalo is India’s primary dairy animal. It
serves an essential role in the agricultural
economy due to its adaptation to hard climatic conditions, resistance to tropical diseases,
and survival under inadequate feeding and
management practices. In 2022–23, India
produced 230.58 million tonnes of milk, of
which 44.18% (101.87 million tonnes) was
contributed by buffaloes1
. Indigenous buffalo breeds such as Murrah, Nili-Ravi, Jaffarabadi, Bhadawari, Surti and other breeds
play a significant role in Indian dairy
growth. The milk obtained from bovine
species (cattle and buffalo) has enabled India
to become the world’s largest milk-producing nation. However, the low productivity
of indigenous buffalo species (~6 kg per
day) is a challenge for sustainable milk production and food security under changing
climatic conditions. To upgrade the genetic
potential of low-producing animals, the Government of India has proposed using
assisted reproductive technologies to produce elite bovine germplasm.

Abstract: A rise in upper ocean temperature in
the central and eastern equatorial Pacific Ocean signals El Niño. The annual thermal event influences the Walker
circulation and disrupts weather patterns worldwide, impacting agriculture,
fisheries and even causing disease
outbreaks.
There is a delay of about one and a
half months in predicting El Niño based
on the temperature of the surface of
the sea. The changes in circulation
cause upwelling and influence the nutrient supply to the uppermost layer of
the sea that receives sunlight. This
leads to changes in the phytoplanktons, tiny plants forming the base of
the marine food chain. Since the phytoplanktons contain chlorophyll-a, their
growth can be detected easily by satellite imagery. Could a drop in chlorophyll concentration during the spring
bloom in the central Pacific predict the
coming of El Niño events?

Abstract: India’s global hunger index of 2022 is 107
of the 121 countries. On the one hand, it is
challenging to end hunger in a population
that is constantly expanding; on either side,
malnutrition is due to the non-availability
of quality nutritious food. Cereal-based
products make up the vast bulk of basic
diets worldwide. Together, maize, rice and
wheat account for 51% of global calorie
consumption, and concerning India, rice
and wheat are the major staple food among
the cereals

Subject: On-farm trial of oyster mushroom cultivation: the technology assessment-refinement for sustainable livelihood and strategic out-scaling
Keywords: On-farm trial, oyster mushroom cultivation, technology assessment and refinement, TOWS matrix.
Abstract: Climate change, land fragmentation, coupled with nationwide lockdown during COVID-19, had put the rural
people of Bihar in financial distress without any alternative livelihood. In this context, oyster mushroom cultivation was considered to be a viable livelihood option
but the existing technology produced less yield with
shorter shelf life. Hence an on-farm trial (OFT) was
undertook by Krishi Vigyan Kendra (KVK), Sitamarhi,
Bihar to assess existing technology, refine it as needed
and then strategize its out-scaling through TOWS
matrix. Out of three substrates (paddy, wheat and
paddy + wheat), the mushroom grown on wheat straw
substrate performed best. Further, blanching (2%
salt + 0.1 citric acid) increased the shelf-life of mushrooms for up to 96 h after harvest fetching highest return.

Title: Disaggregation of daily rainfall data into hourly rainfall data using statistical methods for stormwater management in urban areas

Subject: Disaggregation of daily rainfall data into hourly rainfall data using statistical methods for stormwater management in urban areas
Keywords: Antecedent moisture conditions, hydrological model, rainfall data, stormwater infrastructure, urban areas.
Abstract: In the recent past, low-lying areas close to riverbanks
and urban agglomerations have witnessed frequent
floods due to inadequate mapping of flood zones and
rapidly growing impervious areas in cities/towns. This
inadequacy is due to the use of design storms for run-off
estimates, which do not account accurately for antecedent moisture conditions. Furthermore, when using daily
rainfall data, capturing accurate run-off estimates becomes challenging as rainfall characteristics such as
duration and intensity are not accounted for. These
problems can be addressed with long-term hourly
rainfall data. However, most gauging stations in India
have long-term daily rainfall data and hourly data for
the last few years. There are various global methods to
overcome this data limitation by disaggregating daily
data into hourly data. However, well-established, peerreviewed research on this process is still in infancy in
India. Therefore, a methodology has been developed to
disaggregate long-term daily rainfall data into hourly
rainfall using statistical and probabilistic principles
based on sample hourly data. In this study, the run-off
estimates derived from disaggregated data closely
match those obtained from actual hourly data with
similar characteristics when simulated over the Belagavi
city catchment area in Karnataka, India. The methodology developed relies on sample hourly rainfall, making it
scalable across various locations. It holds promise for
resilient urban stormwater infrastructure planning in
the absence of long-term hourly rainfall data
