Trace gas mixing ratios, carbon, water, and energy exchanges measurements at ARM facilities.

Description

The LBNL-led Carbon project and its associated suite of instruments first deployed in 2001 became part of the ARM Baseline suite of instruments in 2015. The transfer of data acquisition, processing code and QA/QC process has been completed in 2017. The suite of instruments includes the following systems: • AOSGHG: continuous observations of CO2 and CH4 mixing ratios (ENA, OLI) • PGS: continuous observations of CO2 and CH4 mixing ratios (SGP) • GHGFLASK: flask-based observations of trace gas mixing ratios (SGP) • GHGISOFLASK: flask-based observation of trace gases mixing ratios and isotopes (SGP) • CO2FLX: continuous CO2, H2O, and energy fluxes (SGP) • AMC: continuous soil moisture and temperature observations (SGP, NSA, OLI) We report on the status of these observations.
