GOSAT Series and
Global Simulations of Surface CO2 and CH4 using GOSAT Data Based on GOSAT Level 4B CO2 products (V02.07) and GOSAT Level 4B CH4 products (V01.05)：2009-2018.
* Level 4 data products
The Level 4B data product presents global CO2 and CH4 concentrations in three dimensions calculated from the Level 4A data product using the atmospheric transport model. The data product has a horizontal resolution of 2.5x 2.5 and a time step of six hours.
The Level 4A data product shows monthly averaged source/sink strengths (fluxes) of CO2 and CH4 in 64 and 43 regions respectively with their uncertainties that are inversely estimated from the FTS SWIR Level 2 column-averaged mixing ratios, ground-based observational data, and other meteorological data such as wind direction and velocity, using a global atmospheric transport model.
