New 2012 Precipitation Frequency Estimation Analysis for Alaska: Musings on Data Used and the Final Product.

摘要

The major product of this study was a precipitation frequency atlas for the entire state of Alaska; this atlas is available at http://dipper.nws. noaa.gov/hdsc/pfds/. The process of contributing to this study provided an opportunity to (1) evaluate the complete precipitation data-collection program for Alaska and (2) compare the newprecipitation frequency estimates with those published in 1963. It has been known for some time that the precipitation data-collection program in Alaska has many limitations and challenges. This present report summarizes the limitations of the data collection program identified during the study and includes a comparison of the 1963 and 2012 results for selected stations at major population centers. The authors hope thatthis report will lead to improvements in data collection so that better precipitation frequency estimates can be made in the future.
