Description of dataset Eagle Ford Shale CH4 and CO2 emissions (10.5281/zenodo.10278516) Filename: Eagle Ford Shale CH4 and CO2 emissions 11Sep2023.xslx Description: CH4 and CO2 emissions at well-level, gathering-level and plant-level Processing step: both CH4 and CO2 emissions are processed into a gridded format using SMOKE, with no temporal variations. CAMx gridded outputs Domain definition (GRIDDESC) 'LAM_40N97W' 2 33.000 45.000 -97.000 -97.000 40.000 'txs_4km' 'LAM_40N97W' -324000.000 -1584000.000 4000.000 4000.000 189 234 1 'txs_133km' 'LAM_40N97W' -324000.000 -1476000.000 1333.333 1333.333 378 459 1 CAMx configurations: Version 7.10 Simulation time period: 2019 April 1st – October 31st (with a 15-day spin-up) Chemistry turned off Zero initial and boundary concentration of CH4/CO2 Output: Gridded surface concentration and column concentration are provided in the following folder structure: domain/scenario/surface for surface concentration domain/scenario/column for column concentration. Two domains are available: txs_4km and txs_133km. There are ten sets of scenarios for each domain: base: routine CO2/CH4 emissions (10.5281/zenodo.10278516) Event Scenarios 1.33km: 10.5281/zenodo.10261056; 4km: 10.5281/zenodo.10255627 low_100kg/1000kg: 100/1000 kg/hr emission event added with low routine emissions med_100kg/1000kg: 100/1000 kg/hr emission event added with medium routine emissions high_100kg/1000kg: 100/1000 kg/hr emission event added with high routine emissions nearby_low/med/high: 100/1000kg/hr emission events added at nearby locations For example, files under 'txs_4km/base/surface' represent hourly gridded surface CH4/CO2 concentration (ppmv) with a spatial resolution of 4km x 4km. Similarly, files under 'txs_13km/nearby_high/column' represent hourly gridded CH4 column concentration (mol/m2) with a spatial resolution of 4km x 4km under scenario 'nearby_high'.
