Daily degree-day (DD) maps are calculated daily (from Jan 1 of the current year through yesterday) using open source GIS (GRASS) real time and historical temperature data from numerous publicly available weather stations (see table index below) and PRISM temperature maps. See More info. on methodology. With these maps, you may track the extent of DD (heat unit) build-up so far this growing season using the temperature thresholds 32°, 41°, and 50° F. Click on region of interest to get started. Try the Degree-day Mapping Calculator for custom control over options.

Notes: Shortcut tables are available for these Oregon grower networks: Hood River Agrimet/IFPnet/Adcon, The Dalles IFPnet, Medford Adcon, and Milton-Freewater/Walla Walla Adcon
