蒙古高原500m分辨率植被物候及变化趋势数据集(2001–2019年)

蒙古高原500m分辨率植被物候及变化趋势数据集(2001–2019年)基于MODIS土地覆盖动态产品MCD12Q2，通过提取子数据集、镶嵌、投影、拼接后得到蒙古高原植被生长季开始时间(SOS)、生长季结束时间(EOS)和生长峰值时间(DOP)数据集，并通过植被SOS和EOS计算得到生长季节长度(LOS)，并使用Sen+MK方法进一步计算四个物候期的变化趋势数据。文件储存为.tif格式。The Mongolian Plateau 500m Resolution Vegetation Phenology and Trend Dataset (2001–2019) is constructed based on the MODIS Land Cover Dynamics product MCD12Q2. Through sub-dataset extraction, mosaicking, reprojection and stitching, the datasets of vegetation start of growing season (SOS), end of growing season (EOS) and date of peak (DOP) over the Mongolian Plateau are obtained. Additionally, the length of growing season (LOS) is calculated using the vegetation SOS and EOS values. Furthermore, the trend data of the four phenological periods are derived using the Sen's slope + Mann-Kendall (Sen+MK) method. All dataset files are stored in .tif format.
