Special Issue Information

Dear Colleagues,

The atmosphere is essential for Earth’s climate, which is a global concern and widely recognized in both the scientific community and among the lay public. Surface hydrothermal factors are sensitive to the climate, and play an important role in the physical and biochemical processes of soil, as well as the energy exchange system. They directly affect the roots of plants, and have an important impact on the germination of plant seeds and the growth of plants. In modern times, the sources and sinks of atmospheric components are under dynamic change, causing the previous spatio-temporal pattern of radiation balance and surface hydrothermal factors to be disrupted and possibly come to a new balance, which must be carefully studied.

The goal of this Special Issue is to discuss the spatio-temporal pattern of surface hydrothermal factors and atmospheric components in the context of climate change. Therefore, we cordially invite our colleagues in the scientific community to submit their exciting findings to our recently released Special Issue of Atmosphere which relates to “Atmosphere and Surface Hydrothermal Factors”. Potential topics include, but are not limited to, the following:

  • Surface hydrothermal factors (e.g., surface temperature, soil moisture, evapotranspiration) retrieval.
  • Atmospheric components retrieval.
  • Spatio-temporal characteristics of surface hydrothermal factors and atmospheric components.
  • Effects of land use/cover change on hydrothermal factors.
  • Influence of surface hydrothermal factors on agricultural production.
  • Response of ecosystems to surface hydrothermal factors.
  • The source and sink of atmospheric components.
  • Atmospheric components and climate change.
  • Climate change and surface hydrothermal factors.

Manuscript Submission Information

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.

With the rapid development of soil moisture estimation techniques involving remote sensing technology, the sampling designs used in soil moisture research are very important. To estimate the rational sample number for measuring near-surface soil moisture (0–20 cm), a random combination method was used to study the relationship between the average measured soil moisture contents and the true values at given scales. Compared to classic statistics and stratified sampling, the random combination method easily obtained precision estimates from a small number of samples. Moreover, the random combination method was upscaled to further discuss the influence of the coefficient of variation and study-region scale on the rational sample numbers at different scales (2, 10, 20, 40, 80, and 160 m). The results showed that the rational sample numbers for measuring near-surface soil moisture at the 2, 10, 20, 40, 80, and 160 m scales were 2, 5, 5, 8, 20, and 42, respectively, under the relative error of 10% at the 95% confidence level. The rational sample numbers at different scales were proportional to the coefficient of variation and the regional scale. Full article
