Multi-laboratory compilation of atmospheric carbon dioxide data for the period 1983-2023; obspack_ch4_1_GLOBALVIEWplus_v7.0_2024-10-29

This product is constructed using the Observation Package (ObsPack) framework [Masarie et al., 2014; www.earth-syst-sci-data.net/6/375/2014/]. The framework is designed to bring together atmospheric greenhouse gas (GHG) observations from a variety of sampling platforms, prepare them with specific applications in mind, and package and distribute them in a self-consistent and well-documented product. ObsPack products are intended to support GHG budget studies and represent a new generation of cooperative value-added GHG data products. This product includes 530 atmospheric methane datasets derived from observations made by 67 laboratories. Data for the period 1983-2023 (where available) are included.
