The SNPP mission has restored data collection following a spacecraft anomaly that occurred on 26 July 2022. The VIIRS calibration team is evaluating the data to determine any impacts the two-week outage may have had on data quality. This evaluation may take several weeks to complete. Until such time as this analysis is complete and any calibration adjustments can be made, users are cautioned against using these data for scientific analyses.

PACE

Sensor Summary

The Plankton, Aerosol, Cloud, and ocean Ecosystem (PACE) mission is scheduled to launch no earlier than 2023. The mission will carry the Ocean Color Instrument (OCI), which is a hyperspectral radiometer spanning the ultraviolet to near infrared, with additional bands in the shortwave infrared, that is designed to provide measurements for the production of global ocean color, aerosol, and cloud science data records. PACE will also carry two multiangle polarimeters: HARP2 (Hyper-Angular Rainbow Polarimeter 2) and SPEXone (Spectro-polarimeter for Planetary Exploration one), which will provide additional measurements and products to expand our understanding of aerosol and cloud microphysical properties and support advance applications in ocean biology and biogeochemistry.
