The goal of the GHG-CCI project (http://www.esa-ghg-cci.org/) of ESA's Climate Change Initiative (CCI) is to generate global atmospheric satellite-derived carbon dioxide (CO 2 ) and methane (CH 4 ) data sets as needed to improve our understanding of the regional sources and sinks of these important greenhouse gases (GHG). Here we present an overview about the latest data set called Climate Research Data Package No. 3 (CRDP3). We focus on the GHG-CCI project core data products, which are near-surface-sensitive column-averaged dry air mole fractions of CO 2 and CH 4 , denoted XCO 2 (in ppm) and XCH 4 (in ppb) retrieved from SCIAMACHY/ENVISAT (2002-2012) and TANSO-FTS/GOSAT (2009-today) nadir mode radiance observations in the near-infrared/shortwave-infrared spectral region. The GHG-CCI products are primarily individual sensor Level 2 products. However, we also generate merged Level 2 products ("EMMA products"). Here we also present a first GHG-CCI Level 3 product, namely XCO 2 and XCH 4 in Obs4MIPs format (monthly, 5°×5°).

Funding

We thank JAXA and NIES for support and for providing us with GOSAT Level 1 data. We thank ESA and DLR for providing us with SCIAMACHY Level 1 data products. We thank ESA for funding this project and for making GOSAT Level 1 data available via the ESA Third Party Mission archive.
