What's new at PRISM
Alaska

Average monthly and annual precipitation and minimum, maximum, and mean temperature for the period 1981-2010 (completed 2018). Project sponsored by the National Park Service.

Data may be downloaded as graphics or data grids; the corresponding metadata is available separately. Within each category are four folders/files (standard PRISM formats and filenames are used):

  • ppt (precipitation)
  • tmax (maximum temperature)
  • tmin (minimum temperature)
  • tmean (mean temperature)

We suggest reviewing the metadata first to make sure you understand what you are downloading. Like all PRISM data, these files are subject to the PRISM Data Terms of Use.
