Novel Interpretations of Solar-Induced Chlorophyll Fluorescence and Photochemical Reflectance Using Remote Sensing

Dear Colleagues,

Solar-induced chlorophyll fluorescence (SIF) and photochemical reflectance indices (PRIs) provide opportunities to investigate vegetation dynamics under different environmental conditions. Strong relationships between SIF and photosynthesis have been idenitified across multiple temporal and spatial scales, and PRIs are linked with non-photochemical quenching (NPQ) and light use efficiency (LUE). Recent advances in remote sensing techniques have enabled measurements of SIF and PRIs from leaf, canopy, and landscape scales. However, these measurements have been transformed into valuable information, though new applications still require more effort dedicated to the scaling, modelling, and interpretation of SIF and PRIs. Instrumental, atmospheric, structural, and physiological factors are accounted for to establish a quantitative link between SIF, PRIs, and photosynthesis.

This Special Issue aims to showcase studies covering SIF, PRIs, and photosynthesis acquired from different sensors, platforms, species, and environments. Potential topics include, but are not limited to, the following:

• Instrumentations and measurement protocols;
• Retrieval algorithms and calibration/validation methods;
• Vegetation stress detection;
• SIF and PRI modelling,as well as radiative transfer models;
• New applications of SIF and PRIs;
• Vegetation dynamics monitoring;
• Gross primary production estimation;
• Scaling from leaf to canopy;
• Relationships among SIF, PRIs, and photosynthesis.

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. Remote Sensing is an international peer-reviewed open access semimonthly 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 2700 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.
