Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 Raw Payload (PREFIRE_SAT1_0-PAYLOAD) contains the uncurated raw measurements from one of two PREFIRE Thermal Infrared Spectrometers (TIRS-PREFIRE), which is 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 be assimilated into global circulation and other models to predict future conditions more accurately.
This collection contains the raw and uncurated digital number counts for TIRS-PREFIRE aboard PREFIRE Satellite 1 (PREFIRE-SAT1). Data retrieval started in July 24, 2024 and is ongoing. Geographic coverage is global, with the greatest concentration of data in the polar regions. This data has a temporal resolution of 0.707 seconds and is available in binary format.
Raw, Uncurated digital number counts for the sister instrument aboard PREFIRE-SAT2 can be found in the PREFIRE_SAT2_0-PAYLOAD collection.
