Atmospheric GHG Measurements

Improved Emission Estimate

The inverse model is applied to provide improved emission estimates for sub-regions of California. Here we show the map of sub-regions and the resulting seasonally-varying emission estimates. Improved CH4 emissions are estimated for sub-regions of California (6, 7, 8) with large footprint - emission overlap. Some regions show significant seasonal variations in CH4 emissions (e.g., summer rice in region 6) (Jeong et al., 2012).
