Description
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 from the
leak center and from varying leak rates\. Dec02\|03 data was from a 20
standard liters per minute \(slpm\) controlled leak\, Nov01\|04 data are
from a 5 slpm controlled leak\, and the remaining files are from a 10 slpm
controlled leak\. * Measurements were taken downwind relative to a 0.9
metres (leak depth) below-ground gas leak at a test bed with a grass
surface cover.
