IITM

This scheme has five targeted project components focusing on the scientific deliverables, and also allowing for cross-fertilization of innovative research ideas through interconnections among the individual project components. The five sub-components are:

1.  Centre for Climate Change Research (CCCR)

• • Modeling of global and regional climate variability and change using Earth System Models and High Resolution (27 km grid) Climate Models.
  • Conduct ground based measurements of greenhouse gas (GHG) concentrations and fluxes, chemical trace gases, meteorological & land surface parameters.

2. Physics & Dynamics of Tropical Clouds (PDTC)

• • Conduct scientific investigations of aerosol-cloud precipitation interactions in warm and mixed phase clouds, characterize cloud condensation nuclei and ice nuclei particles etc.
  • Develop weather modification research strategies on artificial rainmaking, hail suppression, fog dispersal and reduction of air pollution.

3. Atmospheric Research Testbeds (ARTs)

• • To establish an Atmospheric Research Testbed in Central India for better understanding on processes governing monsoon convection including its diurnal variation and land-atmosphere interactions in core monsoon zone with state of the art instrumentation and UAVs.
  • To establish a small radar network in the Mumbai metropolitan region to provide high-resolution rainfall (both temporal and spatial) flood warning and nowcasting.

4. Metro Air Quality and Weather Service (MAQWS)

• • Research on science of air pollution and forecasting, relevant atmospheric chemistry processes and impact assessment on health and ecosystem through observational campaigns and modelling.

5. Climate Variability and decadal Prediction (CVP)

• • To develop a decadal prediction system based on the in-house Earth System Model for enabling the capability to predict the Indian monsoon and Indian Ocean temperature, sea level etc. about 1-10 years ahead of time.

IITM

• • Establishing a multi-petaflops scale computing facility for the MoES institutes to meet requirement of numerical modeling for weather and climate forecasting, basic research, and observations.
