Climate data was interpolated by ClimatePNW from 1961 to 1990. The input information is longitude, latitude and elevation, and the output data contain all items list below: |
Climate data |
Directly calculated variables: MAT mean annual temperature (°C), MWMT mean warmest month temperature (°C), MCMT mean coldest month temperature (°C), TD temperature difference between MWMT and MCMT, or continentality (°C), MAP mean annual precipitation (mm), MSP mean annual summer (May to Sept.) precipitation (mm), AH:M annual heat:moisture index (MAT+10)/(MAP/1000)) SH:M summer heat:moisture index ((MWMT)/(MSP/1000))
Derived variables: DD<0 degree-days below 0°C, chilling degree-days DD>5 degree-days above 5°C, growing degree-days DD5100 the Julian date on which DD>5 reaches 100, the date of budburst for most plants DD<18 degree-days below 18°C, heating degree-days DD>18 degree-days above 18°C, cooling degree-days NFFD the number of frost-free days FFP frost-free period bFFP the Julian date on which FFP begins eFFP the Julian date on which FFP ends PAS precipitation as snow (mm) EMT extreme minimum temperature over 30 years |
