The NASA Langley Atmospheric Sciences Data Center archives, produces and distributes Earth Science data from NASA Earth Observing System (EOS). Data from the Clouds and the Earth's Radiant Energy System (CERES) instrument on the EOS flagship spacecraft Terra is produced, archived and distributed from the ASDC. The recently released Single Scanner Footprint TOA/Surface Fluxes and Clouds (SSF) product presented a challenge in geographic representation since the product is hourly. To ensure an accurate representation in the ordering interfaces and for subsetting requests, the data is represented by a geopolygon of multiple points. Examples of the improvements this approach gives will be shown.
