Seasonal Fractional Cover Deciles version 3 - Landsat, JRSRP algorithm, Australia coverage

Two fractional cover decile products, green cover and total cover, are currently produced from the historical timeseries of seasonal fractional cover images. These products compare, at the per-pixel level, the level of cover for the specific season of interest against the long term cover for that same season. For each pixel, all cover values for the relevant seasons within a baseline period (1990 - 2020) are classified into deciles. The cover value for the pixel in the season of interest is then classified according to the decile in which it falls. \r\nThis product is based upon the JRSRP Fractional Cover 3.0 algorithm.

当前，基于季节性覆盖比例影像（seasonal fractional cover image）的历史时间序列，已生成两类覆盖比例十分位数产品（fractional cover decile product）：绿色覆盖（green cover）与总覆盖（total cover）。此类产品以像元级为基准，将目标特定季节的覆盖水平与该季节的长期平均覆盖水平进行对比。针对每个像元，将基准时段（baseline period，1990年-2020年）内对应季节的所有覆盖数值划分为十分位数（decile）等级；随后将目标季节内该像元的覆盖数值，按照其所属的十分位数等级完成分类。
本产品基于JRSRP Fractional Cover 3.0算法。
