Entry Title: Surface Radiation Budget (SRB) Release 3.1 Longwave monthly data in native format
Entry ID: SRB_REL3.1_LW_MONTHLY_1
Aerosols Clouds Radiation Budget
Description
The data set contains monthly average global fields of six longwave (LW)surface and Top of Atmosphere (TOA) radiative parameters derived with theLongwave algorithm of the NASA World Climate Research Programme/Global Energyand Water-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 monthly averages 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.
