Map of measurement stations in the Boston network. The black line demarcates the 90 km radius circle in which emissions were optimized and the dashed line bounds the urban domain for study. The blue shading represents the number of housing units with natural gas per square kilometer. The red and blue contour encloses 50% of the average footprint initiated at the COP and BU sites, respectively.

Body
Hourly average atmospheric measurements of CH4 from multiple sites in and around Boston, MA. from September 2012-May 2020

Interannual variation in gross primary productivity (GPP) across conterminous United States. Map of annual mean GPP for 2018 (a) and 2019 (b). Map of the difference in annual mean GPP between 2019 and 2018 (c) wherein red indicates higher GPP in 2019 and blue indicates higher GPP in 2018. The inset in the bottom left corner shows a time series of the average GPP across CONUS for 2018 and 2019.

Body
Estimates of GPP for CONUS from 2018-02-15 to 2021-10-15, based on measurements of solar-induced chlorophyll fluorescence from TROPOMI on the Sentinel-5P satellite platform.
