Title: Quantifying methane emissions from the largest oil-producing basin in the United States from space Methane_flux_Permian_EIBU.nc
Abstract: This file contains the gridded emission inventory based on bottom-up information (EI_BU) for the Permian Basin (27-36N, 108-98W) . The spatial resolution of the data is 0.25 x 0.3125 degree. Here is a brief description on how EI_BU is constructed. Please refer to our paper for detailed information. 1. We start from gridded EPA methane emission inventory (Maasakkers et al., ES&T 2016), which is for year 2012; 2. We extrapolate oil/gas production emissions to 2018 using 2018 Drillinginfo data (well count, well completion, and production) to reflect changes in oil/gas emission activity; 3. We further scale subsectorial production emissions using the ratio between GHGI (2019) and GHGI (2016) for 2013 emissions to account for changes in national average emission factor. The emisch4_og field represents oil/gas-related emissions derived above. The emisch4_anth field represents the sum of all anthropogenic emissions. Non-oil/gas anthropogenic sources are taken directly from Maasakkers et al. (2016). Reference: Yuzhong Zhang, Ritesh Gautam, Sudhanshu Pandey, Mark Omara, Joannes D.
