Hi Kevin,The USGS website and the NRCS website both have info on growing season and degree days.
http://www.usgs.gov/ http://websoilsurvey.nrcs.usda.gov/app/HomePage.htm Good Luck! Quoting kevin <[email protected]>:
I want to retrieve U.S. growing season length or accumulated growing degree days in the recent years based on 50 base temperature. Could you help give me a good reference to obtain these data? It can either be a map or other formats. Thanks
