About this map:
This map shows spatial variability of rainfall in northern Guam during the period from 1971 until 2000. The data were obtained from the Prism Climate Group (http://prism.nacse.org/) in form of an ASCII file. For the purposes of this atlas, Maria Kottermair processed the ASCII file and converted it in several steps to the raster image shown here.
