Title: Aircraft Data (2021) for Flaring & Fossil Fuels: Uncovering Emissions & Losses (F3UEL) Open Access Deposited

Attribute Value
  • Data collected by Mooney aircraft in 2021 within the Bakken region of North Dakota, and offshore of Alaska (North Slope and Cook Inlet) and California. 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. Nitric oxide (NO) and nitrogen dioxide (NO2) were measured by ECOphysics 88 NOe and Teledyne T5000U instruments, respectively. 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 (C) and humidity (%) were collected with the Vaisala HMP60 probe. Aircraft speeds averaged around 70 meters per second.
  • As part of the Flaring & Fossil Fuels: Uncovering Emissions & Losses (F3UEL) project, in 2021 the aircraft measurement platform sampled offshore oil & gas facilities in Alaska and California to quantify facility-level emissions using the approach detailed in Conley et al. (2017). Onshore, the aircraft sampled downwind of flare combustion plumes in the Bakken region of North Dakota. Vertical profiles were 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.

Data Notes:
1) Missing Value indicator = -9999
2) There are uncharacterized offsets in the NO and NO2 measurements. Accordingly, the NO & NO2 data is best suited for relative/differential form of analysis. Contact data creators for recommendations on addressing offset.
