About the Utah Flux Network

The Utah Flux Network (UFN) is a statewide hydrometeorological network established by the Utah Geological Survey (UGS) to measure evapotranspiration, an essential component of Utah’s water budget. UFN uses eddy covariance and surface renewal techniques to monitor water vapor, CO₂, and energy fluxes.

Goals

  • Provide ground-truth data for satellite evapotranspiration estimates

  • Support water banking, drought planning, and climate modeling

  • Enable consumptive use analysis for the Colorado River Compact

Stations

  • Agricultural fields (e.g., Bluff, Wellington, Escalante, Dugout Ranch, Pelican Lake, Desert View, Green River)

  • Wetlands (e.g., Matheson Wetlands, Great Salt Lake Phragmites)

  • Salt flats (e.g., Bonneville Salt Flats)

  • Forests (e.g., Cedar Mesa)

Measurements

  • Net radiation, soil heat flux, latent & sensible heat

  • CO₂, water vapor, wind speed/direction

  • Soil moisture, temperature, and precipitation

  • Air temperature, relative humidity, and barometric pressure
