Description
The Oceano Dunes State Vehicular Recreation Area (ODSVRA) is a large natural source of wind-driven dust emissions that typically include nontoxic particles too large to be inhaled. PM2.5 and PM10 near the Oceano Dunes ODSVRA have been observed to be highest in the afternoons during high wind speeds, and May and October were targeted as the months with the highest average wind speeds (California Air Resource Board, 2022). The sampling site was located downwind of the southern edge of the at the California Department of Fire at Arroyo Grande (hereafter “CDF”) (Oceano Dunes SVRA, 2022). This sampling used limited resources to target different aspects of PM2.5 and PM10, with a focus during the initial sampling from 14 May to 2 June 2019 and 23 September to 5 October 2019 on differences in PM2.5 composition at different times of day. These studies showed that afternoons were consistently the highest concentrations, reducing the need for overnight sampling. Comparisons of offline measured chemical components with online PM measurements indicated the need for gravimetric measurements, which were added for all subsequent studies starting with 27 April to 16 May 2020. PM10 chemical measurements were added for 28 September to 10 October 2020, and they were optimized for high-PM10 mass concentrations for 27 April to 24 May 2021. The local time during these sampling periods at CDF was PDT. This work was funded by the California Parks and Recreation Contract C18V0003/FS#26915.
