Alaska Precipitation Gridded Analysis
The Climate Prediction Center (CPC) daily (1200 - 1200 UTC) rain gauge analysis contains information from about 200-300 stations across Alaska each day in near realtime (within 12 hours). The source of the rain guage data is SHEF (Standard Hydrologic Exchange Format) - encoded precipitation reports from River Forecast Centers.
Resolution: 2 degree x 2 degree
Domain: 49 N - 75 N, 170 W - 130 W
Window: Day 1 analysis is valid for the window from 12Z on day 0 to 12Z on day 1.
Format: Sequential access binary files created on a big_endian platform (e.g. SUN, SGI, HP, etc.). The missing value is 9999.
Analysis Scheme: Modified Cressman (1959) Scheme (Glahn et al. 1985; Charba et al. 1992).
Quality Control: No quality control applied.
