TErraClimate variables

The following variables are provided for download as 30-year climatological monthly summaries or monthly data for each year (1958-present). Data are available on NKN THREDDS servers or through Google Earth Engine. Note that data come as compressed netCDF. Be sure to reference scale_factor and offset commands when looking at the data.

aet (Actual Evapotranspiration, monthly total), units = mm

def (Climate Water Deficit, monthly total), units = mm
pet (Potential evapotranspiration, monthly total), units = mm
ppt (Precipitation, monthly total), units = mm
q (Runoff, monthly total), units = mm
soil (Soil Moisture, total column - at end of month), units = mm
srad (Downward surface shortwave radiation), units = W/m2
swe (Snow water equivalent - at end of month), units = mm
tmax (Max Temperature, average for month), units = C
tmin (Min Temperature, average for month), units = C
vap (Vapor pressure, average for month), units  = kPa
ws (Wind speed, average for month), units = m/s
vpd (Vapor Pressure Deficit, average for month), units = kpa
PDSI (Palmer Drought Severity Index, at end of month), units = unitless
