  "abstract": "<p>The annual hydroperiod of wetlands, which is affected by global trends and human activities, is a critical<br>\necological parameter that shapes aquatic plants&rsquo; and animals&rsquo; distribution and determines available habitat<br>\nfor many of the living organisms. Thus, its estimation is useful for the sustainable management of wetlands.</p>\n\n<p>The hydroperiod map of Danube Delta is named: &quot;Danube_Delta_Hydroperiod_from_1st_Sept_2016_to_31st_Aug_2017_using_Sentinel_2_inundation_maps.tif&quot;. The pixel values range from 0 to 365 (or 366 for leap years) and denote the number of days a pixel is inundated within a year. The map is generated by interpolating satellite-derived inundation maps falling within the period indicated in its filename.</p>\n\n<p>The interpolation approach is the following: For two dates separated by n days, the occurrence of water is compared. If a pixel is inundated on both dates, then it is assumed inundated for n-days. If a pixel is not inundated on both dates, then it is assumed inundated for n/2 days. In the hydroperiod map, the total number of inundation days per pixel is determined by accumulating the inundated days throughout the desired time period.</p>",
