title: | Sounder SIPS: Sun Synchronous 13:30 orbit Climate Hyperspectral InfraRed Product (CHIRP): Calibrated Radiances from S-NPP |
summary: | The CHIRP-CAL Level 1 product for the 13:30 sun-synchronous orbit consists of calibrated radiance spectra at a common resolution derived from hyperspectral instruments on EOS-Aqua, S-NPP, and JPSS-1/NOAA-20 platforms adjusted to form a continuous climate-quality record. |
