An improved digital elevation model (DEM) will be uploaded to the Jason-2/OSTM satellite starting on Monday, May 11, 2009 at 12:00 UTC and will continue through Wednesday May 13, 2009, 15:00 UTC. While the DEM is uploading, no Poseidon-3 altimetry data will be collected over the "visibility circle" of the Jason-2 ground stations: Usingen (USG), Wallops (WCDAS), and Fairbanks (FCDAS). The data loss will be mostly over land, but some ocean data loss may be observed during the 
DEM upload activity. As a consequence, the production of OGDRs, IGDRs, and GDRs will be impacted.
