The First ISCCP Regional Experiment (FIRE) Cirrus 1 Surface Radiation Budget (SRB) Data over Switzerland show results from the International Satellite Cloud Climatology Project (ISCCP) analysis of B3 radiance data (sampled to 25 km). Unlike the standard ISCCP product, these data are reported at the original pixel resolution and contain detailed information about the algorithm decision. Data covers the region from: 30 degrees North to 55 degrees North (+30 to +55), 40 degrees West to 40 degrees East (-40 to +40). (Polar projection covers 55S - 90S or 55N - 90N, maximum; Midlatitude maps cover 55S to 55N, maximum.) The nominal spatial resolution is 25 km for the spatially sampled imaging data. The pixel field of view is 4 km (National Oceanic and Atmospheric Administration (NOAA) data). Earth location (latitude +/- 90 degrees, longitude +/- 180 degrees) is obtained for each pixel from ancillary data.
