Sentinel-2 Data set for Uganda

Optical top of the atmosphere reflectance data from the Earth resource satellite Sentinel-2 for Uganda (2018-2020) was downloaded and processed in a systematic way to bottom of the atmosphere reflectance with the open software FORCE (Framework for Operational Radiometric Correction for Environmental monitoring, see https://force-eo.readthedocs.io/en/latest/). For each year (2018-2020), the number of clear sky observations were calculated and a best available pixel mosaic were created. For each quarter (12 in total), for two vegetation indices (EVI = Enhanced Vegetation Index and NDVI = Normalized Difference Vegetation Index) a number of relevant measures were calculated (minimum, maximum, mean, standard deviation, 5%, 50% (median) and 95% quantiles). The data have 10-meter spatial resolution and are stored in GeoTIFF format.
Data are suitable for studies of vegetation and vegetation changes. More information and details in article published in Data (https://www.mdpi.com/journal/data), 'submitted' 2021-02-15

乌干达地区2018-2020年地球资源卫星哨兵-2（Sentinel-2）的大气顶部光学反射率数据已通过系统方式下载，并利用开源软件FORCE（环境监测业务辐射校正框架，详见https://force-eo.readthedocs.io/en/latest/）处理为大气底部反射率数据。针对2018-2020年的每一年，计算了晴空观测次数并生成最佳可用像素镶嵌图。针对全部12个季度，对两种植被指数——增强型植被指数（EVI，Enhanced Vegetation Index）和归一化差异植被指数（NDVI，Normalized Difference Vegetation Index）——计算了多项相关统计量，包括最小值、最大值、均值、标准差、5%分位数、50%分位数（中位数）及95%分位数。该数据集的空间分辨率为10米，存储格式为GeoTIFF。本数据集适用于植被及植被变化相关研究。更多信息与细节详见发表于《Data》期刊（https://www.mdpi.com/journal/data）的文章，该文章提交日期为2021年2月15日。
