MOESM1 of Assessing Lagrangian inverse modelling of urban anthropogenic CO2 fluxes using in situ aircraft and ground-based measurements in the Tokyo area Ignacio Pisso Prabir Patra Masayuki Takigawa Toshinobu Machida Hidekazu Matsueda Yousuke Sawa 10.6084/m9.figshare.8148299.v1 https://springernature.figshare.com/articles/journal_contribution/MOESM1_of_Assessing_Lagrangian_inverse_modelling_of_urban_anthropogenic_CO2_fluxes_using_in_situ_aircraft_and_ground-based_measurements_in_the_Tokyo_area/8148299 Additional file 1: Figure S1. Detail of the masks used for space averaging and construction of the error covariance matrix. Upper row: rural, urban and sea domains. Lower row: areas corresponding to EDGAR grid cells with flux higher than 1 mg m−2 s−1 (left panel) and 0.1 mg m−2 s−1 (center panel), for reference. Right panel shows the inner domain used when averaging over all areas. 2019-05-17 05:00:00 Tokyo area error covariance matrix 1  mg  m panel MOESM 1 Assessing Lagrangian anthropogenic CO 2 fluxes EDGAR grid cells sea domains 0.1  mg  m Upper row
