We are primarily interested in the atmospheric distribution and the (surface) sources and sinks of the atmospheric gases carbon dioxide (CO2), methane (CH4) and carbon monoxide (CO). Our focus is on satellite and aircraft data and their interpretation.
In particular, we are working on retrieval algorithms used to produce scientific and operational data products from satellites (SCIAMACHY, GOSAT, OCO-2, S5P, ...) and aircraft data (MAMAP).
We are also working on future satellite missions such as Sentinel-5 and the planned European anthropogenic CO2 monitoring (CO2M) mission, a constellation of satellites (planned launch: 2025) based on our CarbonSat concept.
The purpose of this web site is to collect and make available all information related to these activities.
Note that we also maintain several other websites:
Top: Timeseries of satellite-derived XCO2 (left) and XCH4 (right) as retrieved from SCIAMACHY (until 2012), GOSAT (since 2009), OCO-2 (since 2014) and GOSAT-2 (since 2019) radiance spectra. The time resolution is monthly and the spatial coverage is 60S-60N over land. Bottom: Corresponding annual mean growth rates. Details including data access information see corresponding Copernicus press release (10-Jan-2023).
Timeseries and maps of satellite-derived XCO2 retrieved from SCIAMACHY (until 2012), GOSAT (since 2009), OCO-2 (since 2014) and GOSAT-2 (since 2019) radiance spectra. As can be seen, atmospheric CO2 concentrations are increasing despite world-wide efforts to reduce fossil fuel related CO2 emissions.
Timeseries and maps of satellite-derived XCH4 retrieved from SCIAMACHY (until 2012), GOSAT (since 2009) and GOSAT-2 (since 2019) radiance spectra. As can be seen, atmospheric CH4 concentrations are increasing since 2007.
A global map of satellite-derived XCH4 retrieved from TROPOMI onboard the Sentinel-5-Presursor (S5P) satellite. The underlying data can be otained from the University of Bremen TROPOMI/S5P WFMD website as Level 2 (non-gridded) product. The data have been generated using a retrieval algorithm developed in the framework of the ESA GHG-CCI project:
The figure is also available as GeoTIFF file.
