An intra-annual 30-m dataset of small lakes of the Qilian Mountains, northeast of the Qinghai–Tibet Plateau, for the period 1987-2020

<p>Using Google Earth Engine platform and 13,297 Landsat TM/ETM+/OLI images, we released an&nbsp;intra-annual 30-m dataset of small lakes with different water body frequency thresholds (0%, 25%, 50%, 75%, 100%) of the Qilian Mountains region of the Tibetan Plateau from 1987 to 2020, containing 8 attributes: code, perimeter (km), area (km²), latitude, longitude, elevation (m), area error, relative error (%), and subregion. Our published dataset can provide&nbsp;support for small lakes studies across the Tibetan Plateau and other alpine regions of the world.
