Dear Colleagues,

Evapotranspiration (ET) is a key component in Earth’s water, energy, and carbon cycles and affects the climate and ecosystem via a wide range of feedbacks acting on air temperature, humidity, and precipitation. An accurate estimation of ET is therefore a requirement, but it is challenging both in situ and remotely, introducing uncertainties for model parameterization development and validation. Since 1802, when John Dalton published his pioneering work on evaporation, remarkable achievements have been made by the community in understanding ET processes at varying spatiotemporal scales. However, there are numerous remaining questions in critical ET-based science and application from local to global scales due to limitations in our observation and simulation skills.

In this Special Issue, we are calling for papers that address ET scientific topics in coordination with efforts in different regions of the world, aiming to synthesize results at the global scale. We invite papers covering, but not limited to, the following topics:

(1) Better measurements and modeling of ET and its components (soil evaporation, plant transpiration, and canopy interception) at multiple scales from plot to regional and global scales;

(2) Estimating evaporation/sublimation from unconventional land surfaces including water bodies (especially inland lakes), snow, and glaciers;

(3) Challenges and opportunities in quantifying ET trends in a changing climate using state-of-the-art techniques;

(4) Responses and feedbacks of ET to climate change and anthropogenic activities;

(5) Role of ET in drought monitoring, agricultural management, and water resources; and

(6) Employing high-resolution ET products for improved hydrological and/or climate modeling in poorly gauged regions of the world.

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 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. Water 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 2600 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.
