Mission

PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) is a NASA Earth observation satellite mission. It will make global ocean color measurements to provide extended data records on ocean ecology and global biogeochemistry (e.g., carbon cycle) along with polarimetry measurements to provide extended data records on clouds and aerosols.

Limiting rule: No flight through a thick (>4500 ft) cloud layer extending across the freezing level.

max-top 6377 m, mean 4946 m, 81% cover, freezing 4523 m · max cloud-top 6377 m above freezing 4523 m (81% cover in 10 nmi) · no GLM flashes within 25 nmi / 30 min, likely cirrus / stratiform ice rather than cumulus
