Remote Sensing of Land Surface Radiation Budget

Dear colleagues,

The land surface radiation budget (SRB), describing the radiation balance between the incoming radiation and outgoing radiation in both shortwave and longwave spectra domains at the surface, is essential to any land surface models that characterize hydrological, ecological, and biogeochemical processes. Major components of the land surface radiation budget are surface net radiation, heat conduction (i.e., soil heat flux), and turbulent heat flux components (i.e., sensible and latent heating). It has been proven that remote sensing is a valuable data source to accurately map the long-term SRB components at various spatial and temporal resolutions. In particular, many space agencies and organizations around the world have already released various SRB climate data record (CDR) products. However, current existing SRB products are of insufficient accuracy for some applications. The spatial pattern and temporal trend inconsistency are frequently reported in the current satellite derived SRB products. Moreover, the spatial coverage and spatial–temporal resolutions of SRB products also need to be improved. With this Special Issue, we will compile the state-of-art research that addresses various aspects of land surface radiation budget. Potential topics include but are not limited to the following:

• Estimate of the components of the land surface radiation budget;
• New concepts, ideas, and technology of measuring the land surface radiation budget;
• Evaluation of current land surface radiation budget products;
• Scale effect of land surface radiation budget products;
• Downscaling or upscaling issues in land surface radiation budgets;
• Cloud and aerosol radiative forcing;
• Topographic effect modeling and validation;
• Integration of multisource land surface radiation budget products;
• SRB product generation, validation, and analysis;
• Monitoring the long-term variation of land surface radiation budget;
• Assessment and calibration of land surface models;
• Interaction between the SRB and climate change.

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.
