A research quality product of three hourly OLR for the period May 2004 June 2012 is produced from Kalpana-1 very high resolution radiometer (VHRR) radiances over the Indian region (40 degrees S-40 degrees N, 25-125 degrees E) in a regular grid of 0.25 x 0.25 degrees. The quality and usefulness of the dataset is demonstrated here using some illustrative examples. Although these data are available for a relatively short-period, it is shown that they will be potentially more useful than the widely used OLR from NOAA satellites in representing the annual cycles, particularly over the desert and humid oceans, due to their frequent sampling and quality. The active-break periods in the Indian summer monsoon picked up by both the OLR match well. This three hourly OLR estimated from Kalpana-1 VHRR is able to describe the fine-scale structure of the diurnal variation over the region.</p>10aActive break periods10adiurnal variation10ageostationary platforms10aoutgoing longwave radiation1 aMahakur, M.1 aPrabhu, A.1 aSharma, A., K.1 aRao, V., R.1 aSenroy, S.1 aSingh, Randhir1 aGoswami, B., N.  uhttp://library.ncl.res.in/content/high-resolution-outgoing-longwave-radiation-dataset-kalpana-1-satellite-during-2004-2012-0
