Methodology
  • Data collected by Mooney aircraft over Houston and Denver in Summer 2020. Measurements of methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and water vapor (H2O), are collected with the Picarro model 2301-f instrument with wavelength-scanned cavity ringdown spectrometry. Measurements were made at a frequency of 0.33 to 0.5 Hz with an uncertainty of 1.4 ppb CH4. Ozone (O3) was collected by the 2B 205 Dual Beam Ozone Monitor using two detection cells to simultaneously measure ozone scrubbed and non-scrubbed air. Samples were made at a frequency of 0.5 Hz with an average precision and accuracy of 1 ppb. GPS antennae, mounted on the Mooney aircraft, recorded latitude, longitude, altitude, aircraft heading, zonal speed, and meridional speed. Horizontal winds are calculated following Conley et al (2014) . Temperature (Co) and humidity (%) were collected with the Vaisala HMP60 probe. Aircraft speeds averaged around 70 meters per second.
Description
  • Data collected by Mooney aircraft over Houston and Denver in Summer 2020. Flights typically were designed to measure within the boundary layer in a raster pattern perpendicular to wind direction, thus sampling the urban plume repeatedly. Vertical profiles are conducted on each flight to capture the vertical structure and mixing depths of the atmosphere. The data file contains all merged flight data from each flight day.
