PREFIRE Auxiliary Meteorology Data for PREFIRE Satellite 2 R01

Description

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Auxiliary Meteorology Data for PREFIRE Satellite 2 (PREFIRE_SAT2_AUX-MET) contains GEOS-IT analyses and VIIRS satellite data that are subsets and interpolations corresponding to data collected by the PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE) aboard PREFIRE-SAT2. Dual PREFIRE 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_SAT2_AUX-MET contains surface and skin temperatures, land fraction, sea ice concentration, snow cover, surface pressure, temperature profiles, pressure profiles, O3 profiles, wind velocity profiles, and surface type. Science data retrieval started June 29, 2024 and is ongoing. Geographic coverage is global, with the greatest concentration of data in the polar regions. Within the orbital swath there are eight distinct tracks of data associated with the eight separate spatial scenes for each PREFIRE-TIRS. At the beginning of the mission, the approximate scene footprint sizes were 11.8 km x 34.8 km (cross-track x along-track), with gaps between each scene of approximately 24.2 km. The entire swath was ~264 km across. Note that the scene footprint and swath sizes quoted here are for the orbit altitude soon after launch. However, the footprint size will slowly become smaller as the orbit altitude decreases with time. This data has a temporal resolution of 0.707 seconds and is available in netCDF-4. The auxiliary meteorology data for the sister instrument aboard PREFIRE-SAT1 can be found in the PREFIRE_SAT1_AUX-MET collection.
