||The Soddie Lysimeter Array on Niwot Ridge
and is located near treeline, in an open meadow surrounded by ribbon forest.
The Soddie underground laboratory houses the data collection system for
the snow lysimeter array and other meteorological instruments. Meltwater
from the snow lysimeters flow by gravity into tipping
buckets which are connected via 14 switch
modules to a Campbell CR-10 data logger. Data from the meteorological
tower are recorded by a Campbell CR-21X data logger.
The lysimeter array consists of 105 snowmelt
lysimeters, situated in a 40m by 40m open meadow. The lysimeters drain
into PVC tubing that routes meltwater into the underground laboratory.
A meteorological tower is located in
the field next to the lysimeter array. Data recorded includes temperature,
relative humidity, wind speed, wind direction, radiation, and snow depth.
