Daily Degree-Day Maps of Oregon
See also the new page for Hermiston - Downy Brome and Ontario - Lygus Bug
and the new page for Oregon with interactive features
These maps are calculated using the GIS GRASS 4.2.1, and are based on 1) near-real time temperature data from up to 25 AgriMet , 18 HydroMet, 38 National Weather Service , and ca. 80 RAWS weather stations, 2) historical average temperature data from over 200 stations, 3) PRISM monthly max and min temperature maps, and 4) inverse-distance squared interpolations of differences between PRISM map-based and real-time degree-day calculations. See More info. on methodology for creating DD maps. Also try out our new Degree-day Mapping Calculator for more control over calculation and mapping options.
