Special Issue Information

Dear Colleagues,

Most of the ~ 1.7 billion hectares of cropland cover the mid latitudes. Globally, this represents about 13% of land surface, and 21% of croplands are equipped for irrigation. In wide parts of Europe, the USA, Russia, China, and SE Asia, the fraction of cropland is more than 50%. Croplands pose a special challenge to weather and climate models due to their large variety in properties in space and time that are related to differences in phenological development and crop management such as cultivar selection, sowing and harvest dates, sowing density, and fertilization. Most state-to-the art land surface models coupled to atmospheric models do not distinguish between different crops. Only a few simulate their temporal development in dependence of the simulated weather and irrigation. Instead, mean annual cycles of the leaf area index, roughness length, albedo, and green vegetation fraction are still widely applied. However, it is not only crop development that depends on the weather; the vegetation feeds back via moisture and heat fluxes to the atmosphere. Extremes such as heavy precipitation events, droughts, and heatwaves are expected to increase and show a strong dependence on land–atmosphere feedback. Recent crop model implementations show that crop modeling in meteorology is challenging but produce promising results. Crop models need to be computationally efficient and applicable to a wide range of spatial and temporal scales worldwide. Even further challenging is the observation of land–atmosphere interaction throughout the atmospheric boundary layer over croplands. Recent measurement campaigns and established observatories allow for process understanding and quantification of the role of croplands in land–atmosphere feedback.

This Special Issue aims to collect articles on the developments of crop models coupled to weather and climate models, as well as their evaluation and impact on land–atmosphere feedback. We seek articles from the field to the global scale for non-irrigated and irrigated land. Land–atmosphere feedback studies investigating the atmospheric boundary layer above croplands are welcome from modeling and observational perspectives. We welcome original research articles and reviews covering all related topics.

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. Agronomy 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 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.
