A Long-Term Micrometeorological and Hydrological Dataset Across an Elevation Gradient in Sagehen Creek, Sierra Nevada, California

We compile and release ~55 years of daily and ~20 years of hourly
Micrometeorological and hydrological data from Sagehen Creek a 28
km???^2??? watershed with observation sites spanning 1771 to 2670 m. A
USGS gauging station measures streamflow at the catchment outlet.
There are three Snow Telemetry (SNOTEL) stations: Independence
Camp(2128 m), Independence Creek (1962 m) and Independence Lake (2541
m) that measure hourly precipitation, temperature, soil moisture (at
5, 20, and 50 cm), as well as daily snow water equivalent (SWE) and
snow depth. A new method was used to estimate hourly precipitation
data using quality controlled daily totals. A NOAA cooperative
observer (COOP) station measures daily precipitation, temperature,
SWE, and snow depth from 1953-1997 and then measures hourly
precipitation, temperature, SWE, and snow depth, relative humidity,
and solar radiation from 2001 through 2017 2001-present. There are an
additional three towers with data beginning in 2009 measuring snow
depth, SWE, solar radiation, barometric pressure, precipitation,
relative humidity, and temperature: Tower 1 (1934m), Tower 3 (2114 m),
and Tower 4 (2350 m). Wind speed, temperature, and relative humidity
measured at 7.6 and 30.5 m at each site. Data from all stations were
checked for poor QA/QC and substantial and sophisticated gap-filling
techniques were deployed. This dataset holds potential for improving
understanding of orographic processes and their implications for
streamflow generation in a groundwater-dominated watershed. This data
package mirrors the one available at
