Data Sources and Terms of Use

The use of data is conditional on citing the original data sources. Full details on how to cite the individual data are given at the top of each spreadsheet page. In order to facilitate comparison at regional scale, the region mask is provided on a 1°x1° grid as Netcdf files. For research projects, if the data are essential to the work, or if an important result or conclusion depends on the data, co-authorship may need to be considered. The Global Carbon Project – Methane facilitates access to data to encourage its use and promote a good understanding of the methane cycle. Respecting original data sources is key to help secure the support of data providers to enhance, maintain and update valuable data.
