Comparison of GOSAT and GOSAT-2 synchronous observation data.

Caption

Two-dimensional frequency distribution of (a) CO2 concentration over land, (b) CH4 concentration over land, (c) CO2 concentration over ocean, and (d) CH4 concentration over ocean. Dashed lines indicate a range of ±1%. Maps of synchronous observation points are colored by inter-satellite concentration differences in (e) CO2 concentration and (f) CH4 concentration. “#” is number of data, “AVG” and “STD” are average and standard deviation, respectively, “r” is correlation coefficient, and “G1” and “G2” are GOSAT and GOSAT-2, respectively.
