Towards data-driven mass spectrometry in atmospheric science [PDF]
, 2023 Aerosols found in the atmosphere affect the climate and worsen air quality. To mitigate these adverse impacts, aerosol formation and aerosol chemistry in the atmosphere need to be better mapped out and understood. Currently, mass spectrometry is the single most important analytical technique in atmospheric chemistry and is used to track and identify ...

California Agriculture, 2012 Air pollutants, notably particulate matter (PM) with aerodynamic diameter smaller than 2.5 micrometers (PM2.5), are emitted during agricultural burning. We studied a winter period in Imperial County when predominantly bermuda-grass stubble was burned. At

Constraining the atmospheric limb of the plastic cycle
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Microplastic particles and fibers generated from the breakdown of mismanaged waste are now so prevalent that they cycle through the earth in a manner akin to global biogeochemical cycles. In modeling the atmospheric limb of the plastic cycle,

Fumigant emission reductions with TIF warrant regulatory changes
California Agriculture, 2013 With methyl bromide's phase-out, most growers have turned to alternative fumigants, particularly 1,3-dichloropropene (1,3-D) and chloropicrin. These alternatives are tightly regulated because they are classified as toxic air contaminants and volatile ...

Atmospheres and science fiction [PDF]
Cogent Arts & Humanities, 2019 This article proposes to read science fiction through the lens of atmosphere. Atmospheres, of course, have gained increased critical interest in recent years, most noticeably in Hans Ulrich Gumbrecht’s monograph Atmosphere, Mood, Stimmung, but also cognitivists like Peter Stockwell has discussed the use of atmosphere in literary studies.

Perspectives on atmospheric evolution from noble gas and nitrogen isotopes on Earth, Mars & Venus [PDF]
Space Science Reviews 216 (2020) 36, 2020 The composition of an atmosphere has integrated the geological history of the entire planetary body. However, the long-term evolutions of the atmospheres of the terrestrial planets are not well documented. For Earth, there were until recently only few direct records of atmosphere's composition in the distant past, and insights came mainly from ...

Real-time national GPS networks: Opportunities for atmospheric sensing [PDF]
, 2000 Real-time national Global Positioning System (GPS) networks are being established in a number of countries for atmospheric sensing. UCAR, in collaboration with participating universities, is developing one of these networks in the United States.
