Annual Crop Land Information

The annual cropland products were the integrated outcome of the Land use land cover (LULC) output generated at 56m resolution under National Level LULC mapping on 1: 2,50,000 scale using multi-temporal AWiFS project. The study involved use of multi temporal AWiFS data covering Kharif (Aug –Nov), Rabi (Jan- Mar), Zaid (April- May) seasons to address spatial and temporal variability in cropping pattern and other land cover classes.

Broadband Snow Albedo

Broad band Snow albedo is an important geophysical parameter for studies related to weather, climate, and hydrometeorology and so on. Snow has the highest albedo in nature and hence has a significant influence on surface energy budget and on Earth's radiative balance.

Water Bodies Fraction

Water Bodies consists of all surface water bodies viz. reservoirs, irrigation tanks, lakes, ponds, and rivers / streams. The area under water bodies is dynamic in natures and hence multi-temporal satellite data was used for monitoring. An automated extraction algorithm developed is used for quick processing of satellite data acquired from Resourcesat -1, Resourcesat-2 AWiFS sensors (56m spatial resolution) which enables the generation of water body layer.

Forest Fire Regime

Fire regime over India was analysed using the MODIS fire record from 2003 to 2017.The analysis used AQUA MODIS daytime fires for the 2003 - 2017 time period. Only detections with a detection confidence of over 10% and flagged as forest by using the NRSC forest fraction layer were used in the analysis.

Forest Fraction Cover

The status of global forest cover has large uncertainty for several continents on earth owing to the paucity of comprehensive studies related to long term forest cover change. The aim of the present work is to prepare a nation-wide multi-date forest cover database which describes and quantifies historical changes in forests of India.

Hydrological products

Hydrological modeling (Variable Infiltration Capacity Model) framework has been setup at 9min (~16.5km & 13709 grids) grid level for the entire country. Model specific input parameters (Soil, Vegetation, Routing) are prepared for the entire country at 9min grid level . Historical meteorological data has been organized (1951-2013) from various sources and VIC model specific meteorological inputs are prepared.

Indian Soil Datasets

Soil properties (soil depth, soil texture, soil carbon) are important for their key role in supporting ecosystem services, plant growth, water availability and maintaining carbon stocks. Soil depth is defined as the depth (in cm) to a lithic or paralithic contact (USDA Soil Survey Manual). Soil texture in dicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil.

Meso scale Compatible Inputs for MM-5

IRS-P6 AWiFS derived gridded land use/land cover (LU/LC) data over Indian region as input to mesoscale models (MM5 and WRF).So far 25 land use/land cover categories of USGS derived global coverage with different resolutions data are used to run mesoscale models. IRSP6 AWiFS derived LU/LC data with 56m basic resolution has been scaled to 5, 2 minute & 30 second resolutions. Indian region of USGS data is replaced with AWiFS derived data and made compatible to MM5 & WRF model.

Net Eco System productivity–MODIS

The Carnegie-Ames-Stanford Approach (CASA) terrestrial ecosystem model is implemented for simulating long-term monthly Net Primary Productivity (NPP), Net Ecosystem Productivity (NEP), Soil Respiration, Soil Organic Content and associated CO2exchange parameters between India terrestrial ecosystem and atmosphere at 5 km grids during 2001-2014. This model is driven by time varying normalized difference vegetation index (NDVI), climate parameters (air-temperature, precipitation, solar radiation) and land cover and soil attribute maps.

Monitoring dust storms in Thar Desert region

Dust storms are common in arid and semi-arid areas of Thar Desert region. Minute dust particles eroded from Indian Thar desert region especially during the summer months create a blanket of dust haze over western India and the Indo-Gangetic Plains. Study has been carried out over Thar Desert region using INSAT 3Dand MODIS L1B satellite data. Several algorithms such as IR Split window technique, Normalized Difference Dust Index (NDDI), Sand Dust Index, Band Rationing, Modified Normalized Vegetation Index and various band compositions have been applied to discriminate dust pixels from other features. Infrared Difference Dust Index (IDDI), spatial coherence technique have been applied to discriminate dust pixels using INSAT-3D data. The validation of the output shows reasonable agreement with Aerosol Optical Depth (AOD), PM10, wind speed and visibility data.
