The system includes remote access to local meteorological stations for weather&amp;lt;br&amp;gt;conditions, a MM5 model for weather forecast, the MOHID-Land model for the computation of the&amp;lt;br&amp;gt;soil water balance and irrigation scheduling, and a MySQL database for data repository. Despite its&amp;lt;br&amp;gt;complexity, the data necessary to run IrrigaSys is minimal, and include the location of the agricultural&amp;lt;br&amp;gt;field, crop type, sowing and harvest dates, soil texture, irrigation method, and daily\/weekly irrigation&amp;lt;br&amp;gt;depths applied by the farmer. Based on this information, the system automatically downloads the&amp;lt;br&amp;gt;weather data from the meteorological station located closest to the agricultural plot, as well as the&amp;lt;br&amp;gt;weather forecast for the seven days following the current date. The soil water balance is then&amp;lt;br&amp;gt;computed for the previous and following week as well as the crop irrigation needs using the MOHIDLand&amp;lt;br&amp;gt;model. Results are made available via a web interface, a mobile app, SMS, and email. Besides the&amp;lt;br&amp;gt;model outputs, the IrrigaSys further provides the Normalized Difference Vegetation Index (NDVI) for&amp;lt;br&amp;gt;the agricultural field. The NDVI is computed from Sentinel 2 spectral bands with a resolution of 10m,&amp;lt;br&amp;gt;and is updated every time new Sentinel 2 imagery data (with cloud cover &amp;lt; 10%) is available. The&amp;lt;br&amp;gt;IrrigaSys has been developed in close cooperation with the Water Board Association of the Sorraia&amp;lt;br&amp;gt;Valley irrigation district (15360 ha), southern Portugal, over the last 5 years, supporting 103 plots of&amp;lt;br&amp;gt;30 farmers during the last irrigation season. As a result, the main limitation is naturally associated to&amp;lt;br&amp;gt;the difficulty in providing reliable estimates for all field plots based on calibrated model data. As the&amp;lt;br&amp;gt;next step, the service should start automatically identifying the culture status based on satellite&amp;lt;br&amp;gt;information as well as providing fertigation recommendations to farmers.&amp;lt;\/p&amp;gt;\n        <\/jats:p>","DOI":"10.5194\/egusphere-egu2020-9488","type":"posted-content","created":{"date-parts":[[2020,3,9]],"date-time":"2020-03-09T20:40:57Z","timestamp":1583786457000},"source":"Crossref","is-referenced-by-count":1,"title":["IrrigaSys &amp;#8211; a decision support system for irrigation management in the Sorraia Valley region, Portugal"],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9850-6680","authenticated-orcid":false,"given":"Lucian","family":"Simionesei","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7823-4048","authenticated-orcid":false,"given":"Tiago B.","family":"Ramos","sequence":"additional","affiliation":[]},{"given":"Jorge","family":"Palma","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9760-5783","authenticated-orcid":false,"given":"Ana R.","family":"Oliveira","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6571-5697","authenticated-orcid":false,"given":"Ramiro","family":"Neves","sequence":"additional","affiliation":[]}],"member":"3145","container-title":[],"original-title":[],"deposited":{"date-parts":[[2020,3,23]],"date-time":"2020-03-23T18:18:53Z","timestamp":1584987533000},"score":1,"resource":{"primary":{"URL":"https:\/\/meetingorganizer.copernicus.org\/EGU2020\/EGU2020-9488.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,23]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/egusphere-egu2020-9488","relation":{},"subject":[],"published":{"date-parts":[[2020,3,23]]},"subtype":"other"}}
