Climate Data Portal
The CCCR Climate Data Portal is designed to facilitate the dissemination of climate information using a publicly accessible web-based interface applications.

CCCR-IITM ESGF Data Node
The Earth System Grid Federation (ESGF) maintains a global system of federated data centers that allow access to the largest archive of climate data world-wide. The ESGF datanode at the Center for Climate change Research (CCCR) is India's first datanode in the ESGF framework.

High Resolution Climate Change Simulation over South Asia
High-resolution simulations of 20th century climatic variations and future climate projections have been developed at CCCR-IITM, using a global climate model with telescopic zooming (~ 35 km in longitude x 35 km in latitude) over the South Asian region.
These high-resolution simulations, which were performed on the PRITHVI High Performance Computing (HPC) facility at IITM, offer new opportunities to better understand several key regional scientific issues concerning climate change over South Asia - e.g., Monsoons, precipitation extremes, heat waves, droughts and floods, changes in cyclonic weather systems, hydrological cycle etc.
A variable resolution global modeling framework, based on the Laboratorie Dynamique Meteorologie (LMD, France) atmospheric general circulation model (GCM), has been employed for this purpose under a scientific collaboration between CCCR-IITM and LMD.
Monthly outputs of simulated rainfall and surface air temperature for the historical period (1951 - 2005) and 21st century RCP4.5 scenario projection for the period 2006-2095 are presently made available for downloads.

Climate Model Data Extraction Tool
This is a trial version of a Web Interface based on python under development by CCCR-IITM for users to explore and remotely access subsets (some variables in a particular region for a particular time slice) of authorised datasets available on ESGF in the framework of CORDEX South Asia simulations, and download the selected subset in CSV, Text or NetCDF data formats.

COSMOS Soil Moisture Sensor Data
A new cutting-edge COsmic-ray Soil Moisture Observation System (COSMOS) has been launched by Prof. V.K. Gaur, Distinguished Scientist, CSIR Fourth Paradigm Institute, Bangalore & Chairman, Governing Council, IITM on 31 January 2017. A network of field-scale soil moisture monitoring stations is being developed across India (COSMOS-India) under the NERC-MoES program using cosmic-ray soil moisture sensors (CRS).

GHG Observations Data
Systematic GHG monitoring started at Sinhagad (SNG) in 2009. SNG is located 200 km east of the Arabian Sea (73.75 E, 18.35 N, 1600 m asl) over the Western Ghats mountains (Fig.1). Routine air sampling at SNG, collected from a 10-meter meteorological tower at weekly intervals, has been operational since November 2009. This site is free from major emission sources and has prevailing light winds from the south and southeast during afternoon hours. The mean wind speed at the sampling time is typically about 0.5 to 1 m s-1, so the samples are free from local influences. The ambient temperature ranges from 25 to 30 dc. The Sinhagad site was inducted with continuous monitoring using an in-situ CRDS Picarro instrument in 2022
