GIS Modelling of Evapotranspiration with Remote Sensing

Dear Colleagues,

Evapotranspiration (ET) can be estimated from the complex surface energy balance equations. This process plays a decisive role in various water resource management activities, including the required irrigation water, vegetation–atmosphere interactions, and terrestrial ecosystem productivity over a range of spatial and temporal domains. However, the reliable estimation of ET, characterized by complex vegetation–atmosphere interactions, is limited by scarce data availability and a lack of expertise in conceptualizing the real field scenario. Several remote sensing-based ET estimation approaches, particularly those used to estimate sensible heat flux within a smaller spatial domain, are discussed in this Special Issue. This includes Mapping EvapoTranspiration at High Resolution using Internalized Calibration (METRIC) and Surface Energy Balance Algorithm for Land (SEBAL) (Allen et al., 2011). The introduction of a Moderate Resolution Imaging Spectroradiometer (MODIS) satellite, a device that onboards the aqua and terra sensors, provided continuous ET estimates at 250 m spatial and 8-day temporal resolutions. This was performed with the objective of improved irrigation scheduling at an 8-day timescale, in congruence with the general water stress-sensitive period for major crops.

This Special Issue provides an opportunity for budding researchers to publish their research outcomes related to remote sensing applications in evapotranspiration mapping. This Special Issue invites research articles including but not limited to:

1. Catchment-scale Evapotranspiration monitoring
2. MODIS ET product for vegetation monitoring
3. GIS-based crop planning
4. Remote sensing-based hydrological water balance assessment
5. Spatiotemporal vegetation health monitoring
6. Evapotranspiration modeling under scarce data availability scenario
7. Modeling evapotranspiration with soil moisture estimates

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. Hydrology 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 1800 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.
