CERES S-NPP Quick Look Results

These pictures show examples of the first measurements that the CERES instrument on the S-NPP satellite have made. We use data products such as these to validate the accuracy of our Earth energy estimates. As we gain confidence in the proper operation of the instrument and the data interpretation algorithms, the science data products will be archived at the Atmospheric Science Data Center link to external site.

Contributions to these pages are welcome.

Image: NPP First Test Scans


This image is from the first test scans of Langley's Clouds and the Earth's Radiant Energy System (CERES) instrument aboard a NASA Earth-observing satellite launched October 28, 2011 from Vandenberg Air Force Base in California. The CERES instrument targeted the Baltimore-Washington area as the satellite it is aboard passed over the region in the course of its polar orbit. The scans are to make sure planning tools and orbital predictions are accurate. The scans are used for field missions and for ground truth validation purposes.
