Latest Advances and Application in the GNSS-R Field

Dear Colleagues,

The development and enhancement of Global Navigation Satellite System Reflectometry (GNSS-R) have catalyzed significant advancements in Earth observation. GNSS-R data, derived from various platforms, enable a broad range of geophysical parameter estimations, fostering numerous practical applications. The latest developments in the field of GNSS-R include the emerging research area of polarimetric GNSS-R. This technique holds potential for refining our understanding and monitoring capabilities of various Earth-surface processes.

This Special Issue on “Latest Advances and Application in the GNSS-R Field” invites submissions that explore the utilization of GNSS-R data, both those polarimetric and non-polarimetric, focusing on the innovative and applied aspects of this technology for Earth science. We also encourage contributions that explore the synergistic integration of GNSS-R data with other sensor data across different operational frequencies. Such integrations enhance both spatial resolution and temporal sampling, leading to improved geophysical parameter estimations. We invite contributions on the following topics, which include both polarimetric and non-polarimetric GNSS-R applications:

• Applications in oceanography, land surface, and cryosphere studies using both polarimetric and standard GNSS-R techniques;
• Enhanced environmental monitoring through ground-based or airborne GNSS-R measurements, including polarimetric methods;
• The utilization of satellite-based GNSS-R in conjunction with missions like SWOT, NISAR, and SMAP for comprehensive environmental analysis;
• The development of neural network models or classification algorithms that leverage polarimetric GNSS-R alongside traditional methods;
• The combined analysis of GNSS-R data with data from SAR, radiometers, or optical sensors to create multidimensional environmental models;
• Innovative methods for downscaling or enhancing Earth observation data using both polarimetric and standard GNSS-R.

We look forward to your innovative contributions that utilize GNSS-R technologies to push the boundaries of Earth science.

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-anonymized 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.
