PACE OCI V3.1 REPROCESSING
We
have completed a full mission reprocessing of the V3 OCI Level-1B products to incorporate a minor
correction to the
existing collection (see notes), initiated the V3.1 near real time (NRT) processing of all OCI
Level-2 and Level-3 products from 2 July 2025 forward, and stopped the V3.0 forward stream
processing.
See the Full Reprocessing Notes »

PACE & Friends: Cross-Mission Synergy
How can other NASA Earth observation missions compliment your work with PACE?

MISSION SYNERGY: ICESAT-2
NASA's
Ice, Cloud and Land Elevation Satellite-2 (ICESat-2)
satellite uses laser altimetry to monitor elevation changes across Earth's surfaces.
ICESat-2 also provides bathymetry data.
PACE ocean color and ICESat-2 bathymetry data can synergistically create a more complete
picture of coastal ecosystems, advancing applications such as post-disaster seafloor change detection,
coral reef habitat mapping, water quality monitoring in shallow waters, and more.
Thinking of applying PACE & ICESat-2 data together or have questions?
