NOAA Global Greenhouse Gas Reference Network Flask-Air PFP Sample Measurements of CO2, CH4, CO, N2O, H2, SF6 and isotopic ratios of carbon and oxygen at Tall Tower and other Continental Surface Sites, 2005-Present

The Global Greenhouse Gas Reference Network for the Carbon Cycle and Greenhouse Gases (CCGG) Group is part of NOAA'S Global Monitoring Laboratory (GML) in Boulder, CO, USA. The Reference Network measures the atmospheric distribution and trends of the three main long-term drivers of climate change, carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), as well as carbon monoxide (CO) which is an important indicator of air pollution. The Reference Network includes measurements of discrete air samples collected with programmable 12-flask packages deployed at tall tower and various field campaign sites in the continental USA and at the Mauna Loa Observatory, Hawaii. The PFP flask-air samples are analyzed for up to 55 trace gases at NOAA GML in Boulder as well as for stable isotopes of CO₂ and CH₄ at the University of Colorado Stable Isotope Laboratory. At tall tower and observatory sites, GML makes in situ measurements for CO₂ and CH₄, N₂O and CO at a subset of sites. The PFPs provide multiple species information and also are part of a larger quality control system.
