The VHRR images were obtained from the archival of National Satellite Data Centre of the India Meteorological Department, New Delhi. Retrieval methodology and some applications of this data are available in the accompanying article Mahakur et al. (2013) based on which the data is generated. Narrow band to broadband conversion was performed through empirical relations developed using Genetic algorithm [Singh et al. (2007)]. These data are available at three hour intervals (i.e. 00, 03, ? , 18 and 21 UTC) starting May 2004 over the Indian region (400 S - 400N, 250 E - 1250 E) in regular latitude-longitude grid of resolution 0.25 à 0.25 degrees. A file listing the missing hours of data can be found in the README folder. Along with the three-hourly data (3Hrly); daily (DlyAvg) and monthly (MonAvg) averages are also provided in separate folders. The data is written in Classic NetCDF format (http://www.unidata.ucar.edu/software/netcdf/) following the CF conventions (http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cfconventions.html).
