* ASOS is generally better than AWOS, AWOS precip often not present or inaccurate
T = temperature at sub-daily timescale
Tmin, Tmax = daily min and max temperatures
Td = dew point
P = precipitation
Sf = snowfall
SD= snow depth
SWE= snow water equivalent
RH = relative humidity
S=solar radiation
u = wind speed
û = wind speed and direction
In addition, the USGS and Ecology stream gauge networks monitor river flows at 243 and 213 sites respectively.
USGS gauge data date back to 1890s and Ecology to 1996 (majority after 2000).
