Description
We recently transitioned the LBNL-led Carbon project and its associated suite of instruments to ARM baseline observations. We report on the status of ground-based measurements of atmospheric greenhouse gases from continuous analyzers and flask samplers, at Atmospheric Radiation Measurement Program Climate Research Facilities in the US Southern Great Plains (SGP), the Eastern north Atlantic (ENA), and the North Slope of Alaska (NSA).
These observations are designed to quantify trends and variability in atmospheric concentrations of CO2 and other greenhouse gases with the precision and accuracy needed to evaluate ground-based and satellite-based column CO2 and CH4 estimates, test forward and inverse models, and help with the interpretation of ground-based measurements.
