This report describes the first version of PBSsatellite, software designed to simplify the extraction and statistical analysis of gridded satellite data. This software extends the R Project for Statistical Computing, and it uses PBSmapping, an existing R package, to aid in spatial analysis and the production of plots. The tools found in this package provide users with the functionality necessary to work with data from a variety of sources. Additionally, users are able to write their own data interpretation algorithms and provide them as arguments to some analysis functions within this package.
