Replication data for estimating the below-ground leak rate of a natural gas pipeline using above-ground downwind measurements: THE ESCAPE−1 MODEL

Gas leak detectors are currently used to survey for below-ground leaks. However, measurements from gas detectors are not precise in quantifying the below-ground leak rate—data in this submission aimed to quantify the below-ground leak rate of a Natural Gas pipeline., This dataset consists of raw, unprocessed data. The data was collected at 2m Above ground level using a path-integrated methane detector (measurements were sampled using equipment that reports the mixing ratios in parts per million meter). Measurements were taken above a below-ground gas leak., , # Above-Ground Methane Measurements:

\*Summary of dataset contents, contextualized in experimental procedures. \*

* A path-integrated methane detector was set 2 m above ground level.
* A laser screen was positioned 15 to 20 m opposite of the detector.
* Methane measurements were transmitted every 2 seconds during measurements (varied for some data sets)
* The downwind distance from the leak center was either 5 m or 10 m depending on the controlled leak rate
* A total of 11 experiments were conducted.

## Data and file structure

* The files are .csv meaning it can be opened with Microsoft excel or converted to .txt to re-use it
* The data sets contain 2 columns; 1st column is the time column, and the 2nd column is the methane mixing ratios column
* The 1st column is the time column in Mountain Time (one can always convert to any time zone)
* The 2nd column is in parts per million meters (ppm-m)
* The data can be used to re\-produce a gas plume above\-ground at various distances f...
