Optical Gas Sensing in Atmosphere

Dear Colleagues,

Atmosphere dedicates this Special Issue to monitor gases in the atmospheric environment based on optical technology. Different gases have different characteristics, and gas sensing is a vital tool for understanding atmospheric and environmental changes. It is well known that atmospheric gas sensing should be a local effort conducted in concert with global partners; hence, gas sensing with high sensitivity and stability is needed urgently.

Optical sensing methods based on laser spectroscopy are advantageous for atmospheric monitoring in terms of size, cost, and requiring no pretreatment and accumulation of the concentration of the targeted gas samples. In addition, optical methods provide high-precision remote sensing capabilities, fast response, low-detection high stability. Today, laser spectroscopy, including infrared absorption spectroscopy, photoacoustic spectroscopy, and photothermal spectroscopy, is widely adopted for environmental monitoring.

In light of environmental monitoring, we invite you to contribute articles to this Special Issue by reporting on environmental monitoring using laser gas sensing techniques, in particular advanced methods. Potential topics include but are not limited to the following:

1. Photoacoustic spectroscopy;
2. Tunable diode laser spectroscopy;
3. Cavity-enhanced spectroscopy;
4. Laser Raman spectroscopy;
5. Heterodyne laser spectroscopy;
6. Photothermal spectroscopy;
7. Optical sensing technique;
8. Optical gas sensors applications;
9. Frequency comb spectroscopy;
10. Laser sources for spectroscopy.

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 250 words) can be sent to the Editorial Office for assessment.

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.
