0:00 / 1:00:59 GAWTEC & YESS-Community Webinar on GHGs and Atmospheric Composition: DWD Hohenpeißenberg - ICOS

Greenhouse gases are key drivers for climate change. The greenhouse gas concentrations in the atmosphere are defined by their sources and sinks, which vary substantially in space and time. To estimate and control the growth of their emissions, an extensive measuring network is required. The European research infrastructure and network "Integrated Carbon Observation System" (ICOS) https://www.icos-cp.eu/ makes high quality standardised measurements of greenhouse gases. ICOS is a Global Atmosphere Watch (GAW) contributing network.

As part of the German contribution (ICOS-D) to the ICOS Atmosphere network, nine long-term tall tower monitoring stations have been established in Germany to estimate the greenhouse gas fluxes with high spatial and temporal resolution. At each station concentrations of carbon dioxide (CO2), methane (CH4), carbon monoxide (CO) and nitrous oxide (N2O) as well as meteorological parameters are continuously observed at 3 to 5 measurement heights (up to 341 m a.g.l.). The data are used for inverse modelling to provide a spatially resolved picture of emissions (spatial resolution of 0.1 ° x 0.1 °). ICOS-D follows the strong guidelines and quality requirements of ICOS-EU and GAW to assure high quality measurements. The Webinar will cover the German tall tower network, the station set up and the application of ICOS QA/QC procedures. Selected results from the measurements will also be shown.
