ISRO-Geosphere Biosphere Programme (GBP)


About the Center

The Earth’s climate is modulated by Land-Air-Ocean interactions through Geosphere-Biosphere-Atmospheric processes. These interactive forces regulate equilibrium in the weather and climate. Indiscriminate land use practices, fossil fuel burning, increased vehicular traffic, loss of vegetation cover, etc. are leading to exert changes in the radiative forcing reaching the Earth’s surface.
The temporal and spatial scales of changes in the Earth’s climate, result in changes of natural cycles of monsoon, vagaries in the form of natural disasters, increased temperatures on surface and oceans, loss of soil moisture, decrease in the extent of snow/glaciers, changes in plant productivity etc. Cumulatively these inflict irrecoverable changes to the climate. Realizing the importance of temporal and spatial scales in Geospheric and Biospheric exchange processes, Indian Space Research Organization (ISRO) during the 11th Five year plan (FYP), focused its objectives mainly on addressing large-scale issues that contribute to the overall understanding of parameters responsible for our climate change.
No region in the country receives more varied meteorological phenomena than Anantapur (Andhra Pradesh) and its vicinity. And yet, there is no atmospheric science program at the Department of Physics, Sri Krishnadevaraya University (SKU) campus; Anantapur [14.62o N, 77.65o E, 331m above sea level]. Anantapur located in Southeast India represents a very dry semi-arid, rain shadow and continental region of Rayalaseema, Andhra Pradesh, India. This region receives very little rain fall and the average annual rain fall is above the order of 450mm. Within a 50 km radius, this region is surrounded by a number of cement plants, lime kilns, slab polishing and brick making units.
In view of the regional importance ISRO, Bangalore has selected S.K. University, Department of Physics, Anantapur as a Nodal Centre and extended all infrastructure and research facilities worth of 8 crores with the following objectives in various ISRO-GBP activities:

  1. Aerosol Radiative Forcing: On a periodic basis – is contemplated through the establishment of Multi Wave Radiometer (MWR) network and their assimilation into numerical weather forecasting efforts.
  2. Atmospheric Trace Gases Composition and transport: This programme envisages to apportion the sources and sinks of the trace gases and their residence time of transporting to other regions and to identify ecological hotspots.
  3. Atmospheric Dust Composition and Transport: This programme aims to establish aerosols dust composition observatory network and the transport of atmospheric dust from the continental and extra-continental regions to understand on the intra-annual variability of our atmospheric composition and the possible role of dust in regulating radiative forcing.
  4. Atmospheric Boundary Layer Characterization: This aims to establish boundary layer Lidars surveys.
