Entry Title: Surface Radiation Budget (SRB) Release 3.1 longwave daily local data in native format
Entry ID: SRB_REL3.1_LW_DAILY_1
Aerosols Clouds Radiation Budget
Description
The data set contains daily average global fields of six longwave (LW) surfaceand Top of Atmosphere (TOA) radiative parameters derived with the Longwavealgorithm of the NASA World Climate Research Programme/Global Energy andWater-Cycle Experiment (WCRP/GEWEX) Surface Radiation Budget (SRB) Project.There are a total of six parameters in these files as follows:1. TOA Upward Clear-Sky Flux/Clear-sky Outgoing Longwave Radiation (OLR) (clr_toa_up)2. Surface Clear-sky Upward Longwave Flux (clr_sfc_up)3. Surface Clear-sky Downward Longwave Flux (clr_sfc_down)4. TOA All-Sky Upward Longwave Flux/OLR (toa_up)5. Surface All-Sky Upward Longwave Flux (sfc_up)6. Surface All-Sky Downward Longwave Flux (sfc_down)These parameters are derived originally on a 3-hourly temporal resolution. The3-hourly values are averaged into the daily values given in these files. Thecurrent version of the data sets is identified as Release 3.1.The GEWEX LW algorithm uses the Fu et al. (1997) thermal infrared radiativetransfer code requiring atmospheric profile information, cloud, and surfaceproperties. The sources for these inputs are briefly described below. Adetailed description of the algorithm is currently being prepared forpublication.
