PREFIRE Level 1A Calibrated Spectral Radiance from PREFIRE Satellite 2 R01
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/prefire-sat2/prefire/rad_l1a.r01
PREFIRE (Polar Radiant Energy in the Far InfraRed Experiment) Level 1A Calibrated Spectral Radiance from PREFIRE Satellite 2 (PREFIRE_SAT2_1A-RAD) contains calibrated radiance data retrieved from data collected by the PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE) aboard PREFIRE-SAT2.
Description
Dual CubeSats each carry a 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.Digital number counts from the PREFIRE_SAT2_0-PAYLOAD-TLM collection are converted to radiance and calibrated using an internal blackbody target and space-look data.The PREFIRE_SAT2_1A-RAD data are used as input for PREFIRE_SAT2_1B-RAD, which is geolocated radiance.

Given that it is not geolocated, PREFIRE_SAT2_1A-RAD is not useful for direct scientific study.Science data retrieval for this collection started on June 29, 2024, and is ongoing. Geographic coverage is global, with the greatest concentration of data in the polar regions. These data have a temporal resolution of 0.707 seconds and is available in NetCDF-4.Calibrated radiance data for the sister instrument aboard PREFIRE-SAT1 can be found in the PREFIRE_SAT1_1A-RAD collection.
