Special Issue Information

Dear Colleagues,

Physical, chemical, and biological processes transform elements into molecular substances within the various spheres of the Earth system (i.e., atmosphere, biosphere, cryosphere, hydrosphere, pedosphere, geosphere) and circulate the species through the global environment. Emissions of molecular species from the biosphere, cryosphere, hydrosphere, and pedosphere affect the biogeochemistry of the atmosphere and the climate system. Soil-atmosphere exchange is key to understanding the global cycles of CO2, CH4, and N2O and important for NO. Organic compounds emitted by vegetation affect the oxidizing capacity of the atmosphere and are important precursors of carbonaceous aerosol. Cryosphere-atmosphere exchange of NOx, O3, Hg, and Br, Cl, and I species affects atmospheric chemistry in high-latitude regions. Oceanic emissions of biogenic chlorine, bromine, and iodine deplete ozone and produce light-scatering aerosol. We invite manuscripts on process-scale investigations and modeling studies, which evaluate effects of pedosphere-, biosphere-, cryosphere-, and hydrosphere-atmosphere exchange on atmospheric biogeochemistry. Submissions are also invited on investigations of biogeochemical processes in the pedosphere, biosphere, cryosphere, and hydrosphere, which generate trace gas emissions that determine atmospheric composition and affect the climate system.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Climate warming and vegetation composition change are expected to influence greenhouse gas emissions from boreal peatlands. However, the interactive effects of warming and different vegetation compositions on N2O dynamics are poorly known, although N2O is a very potent greenhouse gas. In this study, manipulated warming and vegetation composition change were conducted in a boreal peatland to investigate the effects on N2O fluxes during the growing seasons in 2015 and 2016. We did not find a significant effect of warming treatment and combination treatments of warming and vegetation composition change on N2O fluxes. However, sedge removal treatment significantly increased N2O emissions by three-fold. Compared with the treatment of shrub and sedge removal, the combined treatment of warming and shrub and sedge removal significantly increased N2O consumption by five-fold. Similar to N2O fluxes, the cumulative N2O flux increased by ~3.5 times under sedge removal treatment, but this effect was not significant. In addition, the results showed that total soil nitrogen was the main control for N2O fluxes under combinative treatments of warming and sedge/shrub removal, while soil temperature and dissolved organic carbon were the main controls for N2O release under warming combined with the removal of all vascular plants. Our results indicate that boreal peatlands have a negligible effect on N2O fluxes in the short-term under climate change, and environmental controls on N2O fluxes become increasingly important under the condition of warming and vegetation composition change.
