Research Objectives

One of the challenges in carbon cycle research is the vast range of scales, from plants to continents, that must be bridged with measurements and models. The Atmospheric and Radiation Measurement (ARM)/Lawrence Berkeley National Laboratory (LBNL) Carbon Project is making a coordinated suite of carbon concentration, isotope, and flux measurements to support a range of scaling and integration exercises, including those proposed for the North American Carbon Program:

  • Quantify the regional atmospheric CO2 budget
  • Predict carbon fluxes, and the effect of land use and climate on them
  • Link local processes to regional and global models

figureDiurnal cycle of CO2, PBL height, and wind speed, may 16-22, 2002. Data were collected at the ARM Central Facility: CO2 concentrations are from the continuous precise system at 60 m tower; red and yellow symbols are NOAA-CMDL flask data. PBL height was estimated from radiosonde profiles. Windspeed was measured at 4 m at the base of tower.
