Abstract

A mobile measurement campaign from June 23-26, 2024 was conducted to detect and quantify CH₄ emissions within about 8 km of the SGP site. Using a LI-COR LI-7810 tracer gas analyzer mounted on a vehicle, we sampled CH₄ along predefined routes surrounding a suspected source area around the SGP ARM site. Measurements were collected between 04:30 and 09:00 local time when the PBL was shallow, increasing sensitivity to surface emissions. Driving speeds were kept below 5 mph to minimize pressure-related artifacts.

ARM Carbon Cycle Gases Flasks at SGP Site

Dataset Biraud, Sebastien

Data from flasks are sampled at the Atmospheric Radiation Measurement Program ARM, Southern Great Plains Site and analyzed by the National Oceanic and Atmospheric Administration NOAA, Earth System Research Laboratory ESRL. The SGP site is included in the NOAA Cooperative Global Air Sampling Network. The surface samples are collected from a 60 m tower at the ARM SGP Central Facility, usually once per week in the afternoon. The aircraft samples are collected approximately weekly from a chartered aircraft, and the collection flight path is centered over the tower where the surface samples are collected. The samples are collected by themore » ARM and LBNL Carbon Project.« less

Positive and Negative Ion CIMS Measurements, SGP, May-June 2024

Dataset Casalnuovo, Dominic ; Troller, Christine ; Kiguru, Joy ; ...

The negative ion measurements were taken using two LTOF-CIMS with two different nitrate inlets. The data labeled Aerodyne_Inlet used an Aerodyne nitrate inlet. Data labeled PCC used a custom transverse inlet. The positive ion measurements were taken using one LTOF-CIMS with hydronium as an ionization reagent using a custom transverse inlet with an inlet voltage difference of 700 V. See https://doi.org/10.1021/acs.jpca.2c01672 for more information. Peaks were autofit using tofware. Positive ion data is published in the form of peak signal/reagent signal. Data files of peak signal/reagent signal for the two mass spectrometers for the negative ion measurements are separate. Concentrations ofmore »« less
