Site Description and Sensors

11 flux towers were operated throughout the Heber City valley region, Utah. Towers comprised of two 30 m multilevel flux profile Rohns, i.e. supersites, and ten single low-level flux stations.

Refer to the table below for site locations and sensor configurations around Heber City.  Note, site names in brackets are the short names used in the netCDF files.

Most of the sites were similarly instrumented.  At the top of each site's tower are:

  • Sonic anemometer and open-path infrared H2O/CO2 gas analyzer (Campbell CSAT3AW/EC150) for turbulent fluxes,
  • Slow-response temperature/humidity sensor (NCAR SHT)

All soil sensors (NCAR 4-level Tsoil, Meter EC-5 Qsoil, REBS HFT Gsoil, and Hukseflux TP01 Csoil) were buried at 0--5cm layer near the base of towered sites.

Radiometers are mounted separately on darkhorse tripods and are considered near-surface measurements.

Ott disdrometers are also set-up separately and close to the base of the towers.
