Linking Montane Soil Moisture Measurements to Evapotranspiration Using Inverse Numerical Modeling

摘要: The T.W. Daniel Experimental Forest (TWDEF) is located in the Bear River Range of Wasatch Cache National Northern Utah United States. site represents high-elevation (2600 m) environmental conditions Intermountain Region within a patchwork four predominant montane vegetation types (aspen, conifer, grass, and sagebrush). Monitoring began at study 2008 where type has one primary two secondary weather stations, each station adjacent to three-3 x 3 meter instrumented sub-plots. Each automated micrometeorological towers (AMT) records air temperature vapor pressure, net radiation, precipitation, snow depth, wind speed direction as well depth every 30 minutes. Secondary provide measurements. subplot includes soil measurements 10-, 25and 50-cm depths temperature, electrical conductivity, dielectric permittivity, water content matric potential. An eddy covariance tower provides heat flux addition CO2 flux, direction. A cosmic ray neutron probe areal averaged moisture covering entire area.
