The INSAT-3D Outgoing longwave radiation (OLR), a fast-delivery level-2 product at pixel resolution, is being generated operationally from every half hourly acquisition of Imager Payload of INSAT-3D.In addition to this, binned daily and monthly OLR products are also generated.The OLR is estimated from the radiance observations in the infrared windows (TIR1: 10.3-11.3μm,TIR2: 11.5-12.5μm)and water vapor (WV: 6.5-7.1 μm) channels of INSAT-3D Imager.In the present study, OLR estimated using the INSAT-3D Imager radiance observation is validated with the CERES (Cloud and Earth's Radiant Energy System; on board NPP satellite) from February, 2014 to December, 2017.For the uniform scenes, OLR estimated using INSAT-3D Imager radiance is of good quality with mean CC 0.93, bias -5.03 Wm -2 & RMSD 10.39 Wm -2 and it could be used in the various applications studies.
