Description
The data set contains global fields of instantaneous 3-hourly values of threelongwave (LW) surface radiative parameters derived with the Quality-Check LW(QCLW) algorithm of the NASA World Climate Research Programme /Global Energy andWater-Cycle Experiment (WCRP/GEWEX) Surface Radiation Budget (SRB) Project.There are a total of three parameters in these files as follows:1. Surface Downward Longwave Flux (DLF), 2. Surface Net Longwave Flux (NLF), and3. Surface Longwave Cloud Radiative Forcing (LWCRF).These parameters were derived on a 3-hourly temporal resolution (i.e., a globalinstantaneous gridded field every 3 hours), namely, at UT hours 00, 03, 06, 09,12 15, 18, and 21 for every day of the month. The current version of the datasets is designated as Release 3.0. It covers a period of 24.5 years from July1983 to December 2007.
