Preferred term

PREFIRE-SAT2  

Definition

  • PREFIRE will document, for the first time, variability in spectral fluxes from 5-45 μm on hourly to seasonal timescales.Two 6U CubeSats in distinct 470–650 km altitude, near-polar (82°-98° inclination) orbitseach carrying a miniaturized IR spectrometer, covering 0- 45 μm at 0.84 μm spectral resolution, operating for one seasonal cycle (a year). The Arctic is Earth’s thermostat. It regulates the climate by venting excess energy received in the tropics. Nearly 60% of Arctic emission occurs at wavelengths > 15 μm (FIR) that have never been systematically measured. PREFIRE improves Arctic climate predictions by anchoring spectral FIR emission and atmospheric GHE. https://prefire.ssec.wisc.edu/ (en)
