TF-2: AES Flux Tower Measurements for BOREAS: Exchange of Energy, Water vapor and Trace Gases Project (SSA-OA)


P.I.(s): Gerry den Hartog -- Atmospheric Environment Service (AES)
Co-I(s): R.E. Mickie, Harold H. Neumann, N.B.A. Trivett -- AES

Objectives: To quantify and examine the controlling factors for CO2, O3, CH4, N2O exchange at the SSA-OA site in PANP and to determine diurnal and seasonal surface energy fluxes at the same site. This study complements TF-1. The broader objectives of the combined proposals include determination of the annual cycle for carbon and nitrogen at the site, with trace gas measurements now also including CO, NO, NO2, NH3, and possibly terpenes. Four types of measurements were done:

  1. eddy correlation flux measurements of momentum, sensible heat, latent heat, CO2, O3, CH4, and N2O above the canopy
  2. within and above canopy profiles of temperature, CO2 and O3
  3. half-hour means of wind speed, wind direction, incoming solar radiation, net radiation, PAR, temperature, relative humidity, wet precipitation, CO2, O3, CH4, and N2O above the canopy, IR canopy temperature, and soil heat flux and temperature
  4. tethersonde profiles including O3
