SCOAPE-II Sondes Data

Description

SCOAPE2_Sondes_Data is the ozonesonde data collected during the Satellite Coastal and Oceanic Atmospheric Pollution Experiment - II (SCOAPE-II). Data collection for this product is complete. The Outer Continental Shelf Lands Act (OCSLA) requires the US Department of Interior Bureau of Ocean Energy Management (BOEM) to ensure compliance with the US National Ambient Air Quality Standard (NAAQS) so that Outer Continental Shelf (OCS) oil and natural gas (ONG) exploration, development, and production do not significantly impact the air quality of any US state. In 2017, BOEM and NASA entered into an interagency agreement to begin a study to scope out the feasibility of BOEM personnel using a suite of NASA and non-NASA resources to assess how pollutants from ONG exploration, development, and production activities affect air quality. An important activity of this interagency agreement was the Satellite Coastal and Oceanic Atmospheric Pollution Experiment (SCOAPE), a field deployment that took place in May 2019, that aimed to assess the capability of satellite observations for monitoring offshore air quality. The outcomes of the study are documented in two BOEM reports (Duncan, 2020; Thompson, 2020). SCOAPE-II was completed in May 2024 as a follow-on to SCOAPE-I. The primary objectives of SCOAPE-II were to collect shipboard in-situ data and learn more about plumes from oil and gas in the Gulf of America; and conduct validation of NO2 columns from the TEMPO instrument and assess the feasibility of using hourly scans for monitoring air quality. SCOAPE-II also introduced an aircraft component to support comparisons with in-situ and satellite observations. Flights with the AVIRIS-3 instrument were conducted during the primary campaign period, targeting methane column enhancements. A separate flight period occurred in October 2024 to conduct observations of NO2 plumes at deep water targets utilizing the Geostationary Coastal and Air Pollution Event (GEO-CAPE) Airborne Simulator (GCAS) instrument. To address BOEM’s goals, the SCOAPE science team conducted surface-based remote sensing and in-situ measurements, which enabled a systematic assessment of the application of satellite observations, primarily NO2, for monitoring air quality. The SCOAPE field measurements consisted of onshore ground sites, including in the vicinity of the Louisiana Universities Marine Consortium (LUMCON; Cocodrie, LA), as well as those from University of Southern Mississippi’s Research Vessel (R/V) Point Sur, which cruised in the Gulf of America from 10-18 May 2019. Based on the 2014 and 2017 BOEM emissions inventories as well as daily air quality and meteorological forecasts, the cruise track was designed to sample both areas with large oil drilling platforms and areas with dense small natural gas facilities. The R/V Point Sur was instrumented to carry out both remote sensing and in-situ measurements of NO2 and O3 along with in-situ CH4, CO2, CO, and VOC tracers which allowed detailed characterization of airmass type and emissions. In addition, there were also measurements of multi-wavelength AOD and black carbon as well as planetary boundary layer structure and meteorological variables, including surface temperature, humidity, and winds. A ship-based spectrometer instrument provided remotely-sensed total column amounts of NO2 and O3 for direct comparison with satellite measurements. Ozonesondes and radiosondes were also launched 1-3 times daily from the R/V Point Sur to provide O3 and meteorological vertical profile observations. The ground-based observations, primarily at LUMCON, included spectrometer-measured column NO2 and O3, in-situ NO2, VOCs, and planetary boundary layer structure. A NO2sonde was also mounted on a vehicle with the goal to detect pollution onshore from offshore ONG activities during onshore flow; data were collected along coastal Louisiana from Burns Point Park to Grand Isle to the tip of the Mississippi River delta. The in-situ measurements were reported in ICARTT files or Excel files. The remote sensing data are in either HDF or netCDF files.
