Ground-based sampling has different capabilities, e.g. these days you can mount a small mass spectrometer (see the ones going to Mars, the Moon) or related devices on a drone and get data about a much wider range of particulates and compounds. e.g.
"VOC Sampler on a Drone Assisting in Tracing the Potential Sources by a Dispersion Model - Case Study of Industrial Emissions" (2023)
> "Two plants which manufacture petrochemical products at an industrial complex in Kaohsiung City, southern Taiwan, were applied as the targets for VOCs sampling and further qualitative and quantitative analysis in the laboratory. Aromatic hydrocarbons, including toluene of 433 ppb, ethylbenzene and xylenes of 100–200 ppb and phenol of 111 ppb were identified."

US EPA also has a similar program.
