Title of Data Set: Permian Basin: in-situ tower greenhouse gas data

Date of final version of data set: 01-2022 (last updated)


Abstract: 

The Permian Basin in-situ greenhouse gas network was designed to measure atmospheric mole fractions of methane to be used in conjunction with transport modeling to determine methane emissions from the Permian Basin oil and natural gas extraction area in Texas/New Mexico. The current network includes 5 measurement sites with continuous measurements of CH4, 4 sites with measurements of CO2, 2 sites with measurements of the isotopic ratio of methane, and 1 site with measurements of H2S.

Calibration cylinders used at the Permian Basin Tower Network sites.  
Within each site, the cylinders are listed in order of use.  
*δ13CH4 values are based on field calibrations of the cylinders.
