Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 Raw Curated Payload R01

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 01:57 PM | Dataset Last Updated: June 23, 2026
Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 Raw Curated Payload (PREFIRE_SAT1_0-PAYLOAD-TLM) contains the curated 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, curated digital number counts for TIRS-PREFIRE aboard PREFIRE Satellite 1 (PREFIRE-SAT1). Data retrieval started in July , 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. The PREFIRE_SAT2_0-PAYLOAD-TLM collection contains raw, curated digital number counts for the sister instrument aboard PREFIRE-SAT2.
