Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Surface Emissivity Sorted All-sky Climatology from PREFIRE Satellite 2 R01

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Surface Emissivity Sorted All-sky Climatology from PREFIRE Satellite 2 (PREFIRE_SAT2_3-SFC-SORTED=ALLSKY) contains monthly climatologies of the Level 2 PREFIRE Surface Emissivity from the PREFIRE Satellite 2 collection (PREFIRE_SAT2_2B_SFC), which is derived from data collected by the PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE) aboard PREFIRE-SAT2. Dual CubeSats each carry a PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE), a push broom spectrometer with 63 channels measuring mid- and far-infrared (FIR) radiation from approximately 5 to 53 µm. Most polar emissions are in the FIR but have not been measured on a large scale. PREFIRE aims to fill knowledge gaps in the global energy budget by more accurately characterizing polar emissions. This information will then be assimilated into global circulation and other models to predict future conditions more accurately.PREFIRE_SAT1_3-SFC-SORTED-ALLSKY climatologies include 1) gridded, time-averaged spectral emissivity sorted by surface type, and 2) gridded standard deviations of time-averaged spectral emissivity sorted by surface type. The grids are 1°x1° and time averaging is currently monthly. Spatially, the cross-track dimension is retained, which consists of 8 distinct tracks. Full swath climatologies will be generated in addition to ascending- and descending-only subsets to account for diurnal variability. The purpose of this collection is to identify surface emissivity behaviors based on surface type and to assimilate PREFIRE surface emissivity data into climate models to further understand and more accurately predict future climates.The data format is NetCDF4.The sorted surface emissivity climatologies for the sister instrument aboard PREFIRE-SAT1 can be found in the PREFIRE_SAT1_3-SFC-SORTED-ALLSKY collection.
