Special Issue "Estimating Inland Water Quality from Remote Sensing Data"
Deadline for manuscript submissions: 30 June 2021.
We would like to invite you to submit original and innovate manuscripts to a Special Issue that specifically addresses “Estimating Inland Water Quality from Remote Sensing Data” in the journal of Remote Sensing.
Water quality is an extremely important environmental factor for ecosystem, human beings and their economic activities, as well as their health. Freshwater quality data and products are widely use to support water ressources management and timely decision making. However, these data are scarce at the global, regional and national levels, due to the lack of monitoring networks and capacity.
In recent decades, high and moderate resolution sensors on board satellite platforms (e.g., S2, L8, S3, MODIS) have allowed for remote sampling and monitoring of the inland water quality parameters at synoptic temporal and spatial scales, offering a cost-effective approach to studying changes in water quality trends, allowing, for instance, one to characterize the impact of sediment fluxes within a drainage basin, phytoplankton biomass, and lake trophic function, as well as the brownification of lakes. However, compared to groundbase platform, which allows one to measure physiochemical parameters (potential hydrogen ions pH, temperature, electric conductivity EC, salinity, total dissolved solids TDS, total suspended solid TSS, turbidity and total alkalinity), organic parameters (biochemical oxygen demand BOD, total organic carbon TOC, dissolved organic carbon DOC, total inorganic carbon TIC) and microbiological parameters (total colloform TC, cholorophyll chl-a), the range of water quality parameters that can be retrieved from satellite remotely sensed data is restricted to only a few optical properties of a water body, due to a limited number of multispectral bands, such as TSS, turbidity, algal pigments, and dissolved organic substances, supplemented with additional surface water temperature data. The coupling approach allowing for the integration of several remote sensing sensors (satellites, airbornes and drones), modelling products (hydrodynamic and biological models), as well as in situ measurements, remains a promising strategy for inland water monitoring at high temporal and spatial resolution. The new generation of geostationary sensors allows one to integrate water quality information at near real-time, by yielding new insight into temporality and monitoring water quality, and specifically cyanobacteria blooms, phenological changes, etc. Similarly, the use of drones equipped both with multispectral to hyperspectral, or even thermal instruments use, has proven to be useful for mapping small water bodies that are not resolvable at satellite spatial resolution, or harder to access, in conjunction with traditional sampling methods for developing different water quality indicators, with which strong correlations can be found.
In short, this Special Issue aims to collect recent developments, methodologies, and innovate applications of remote sensing for generating inland water quality indicators, and derived products, from different platforms (i.e., satellite, airborne and UAV-based remote sensing) and in situ measurements. Both applied and theoretical research contributions on inland water dealing with new algorithms and methodology developments are cordially solicited.
Submissions are encouraged to cover a broad range of topics, which may include:
- Novate remote sensing techniques to assess inland water quality,
- Large areas (global and regional) water quality parameters mapping in inland water,
- Temporal variability (changes/trends/shifts) of water quality in inland waters,
- Integration of multisource remote sensing for assessing water quality indicators,
- Integration of hyperspectral imagery with ground-based datasets.
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 papers will be 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. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.
