Greenhouse Gases CCI project

 

ObjectiveTeamData and documentationPublications |  ImagesContact us

Summary

Carbon dioxide (CO2) and methane (CH4) are the two most important anthropogenic (“human-made”) greenhouse gases (GHG) driving global climate change. Increasing atmospheric concentrations of these Essential Climate Variables (ECVs) leads to global warming with adverse consequences such as rising sea levels. It is therefore important to monitor the spatial distribution and the time evolution of these gases and to improve our knowledge of their various natural and anthropogenic sources and sink. 

The focus of the previous GHG-CCI project (2010-2018) was to improve retrieval algorithms needed to generate high-quality COand CHatmospheric data products from the satellite sensors SCIAMACHY/ENVISAT, GOSAT, and IASI. These products are since 2018 generated operationally via the Copernicus Climate Change Service and they are available via the Copernicus Climate Data Store for all interested users. Currently available are data products for 2003-2017. Improved data products for 2003-2018 (see Reuter et al., 2020) will be available soon.

The focus of the new GHG-CCI+ project, which started in March 2019, is to perform research and development needed to generate new ECV COand CHsatellite-derived products, which have not been generated in the GHG-CCI pre-cursor project (see Objective for additional information).

 

Objective

The objective of the GHG-CCI+ project is to further develop retrieval algorithms needed to generate new high quality satellite-derived COand CHatmospheric data products. These ECV data products are column-averaged dry-air mole fractions (molecular mixing ratios) of COand CH4, denoted XCOand XCH4, respectively. Specifically, the following products will be generated:

  • XCOproducts: 
    • CO2_OC2_FOCA: retrieved from OCO-2 using University of Bremen’s FOCAL algorithm
    • CO2_TAN_OCFP: retrieved from TanSat using University of Leicester’s UoL-FP (or OCFP) algorithm
    • CO2_GO2_SRFP: retrieved from GOSAT-2 using SRON’s RemoTeC (or SRFP) algorithm
  • XCHproducts:
    • CH4_S5P_WFMD: retrieved from Sentinel-5-Precursor (S5P) using University of Bremen’s WFM-DOAS (or WFMD) algorithm
    • CH4_GO2_SRFP and CH4_GO2_SRPR: retrieved from GOSAT-2 using SRON’s RemoTeC algorithm (SRFP for the “full physics” product and SRPR for the “proxy” product)

After validation and initial user assessments, the data products are made available via the CCI Data Portal for all interested users. Each year a new data set will be released using improved algorithms and extended data coverage. The planned dates for product release are:

  • Data set CRDP5: 
  • Data set CRDP6:
    • Available in March 2021
    • Products: all (see above)
  • Data set CRDP7:
    • Available in March 2022
    • Products: all (see above)
