Patterns in ground-level methane and carbon dioxide in summer in the Mackenzie-Beaufort Delta Region

A .csv file containing atmospheric CH₄ and CO₂mixing ratios for the Mackenzie-Beaufort Delta region of the Northwest Territories, Canada. Data was collected from July 16^th- 19^th, 2019, n= 85,184 samples. Data was collected during mobile surveys using a truck mounted Picarro G2210i analyser, while driving on public roads with little traffic. The sample inlet was located on the grille of the truck at a height of about 1.25 m. Time and GPS coordinates were recorded for each measurement and corrected to reflect the lag in transport time from the sample inlet to the analyzer. Gas mixing ratios were standardized to Ameriflux FB04306 breathing grade air (benchmarked to 0.5 ppb). All sample times have been converted to Greenwich Mean Time (GMT).
