Dataset Name Description
This program is designed to compute statistical properties of gridded ASCII files from source datasets. The program was originally designed to process PRISM climate data , however its scope has been expanded to be able to process any gridded ASCII file. README

ArcGIS Toolbox includes tools to calculate precipitation minus potential evapotranspiration (P-PE) for PRISM and GCM data available on our data page. To use this tool you must have ArcGIS 9.x and install the tool into ArcToolbox. The tool is zipped using 7-zip. To install the toolbox,

  • Save the Toolbox for P-PE.tbx to a folder on you PC.
  • Right-click on the ArcToolBox icon at the top of the ArcToolBox display > Add Toolbox...
  • Navigate to folder where you stored the P-PE toolbox, select the toolBox, and click Open. When opening, the Toolbox for P-PE automatically installs. No reboot is necessary.
