I downloaded radiation CER_SSF_Aqua-FM3-MODIS_Edition4A data, but they are instantaneous and have big size.
Is there any other hourly radiation data set with a good horizontal resolution (20-50 Km), or is there any recommended method to transform instantaneous radiation data to hourly data.
The CERES_SYN1deg_Ed3A product provides 3-hourly TOA and surface fluxes at 1x1 deg spatial resolution. It is available at:
In about a month or two, CERES_SYN1deg_Ed4A will be available providing 1-hourly TOA and surface fluxes at 1x1 deg spatial resolution. There are no plans to produce hourly data at a 20-50 km spatial resolution.
