资源简介:
The Total Productivity (TPROD), one of the Vegetation Phenology and Productivity (VPP) parameters, is a product of the pan-European High Resolution Vegetation Phenology and Productivity (HR-VPP) component of the Copernicus Land Monitoring Service (CLMS). The Total Productivity (TPROD), or large integral, is the growing season integral computed as the sum of all daily Plant Phenology Index values between the dates of the season start (SOSD) and end (EOSD). The Plant Phenology Index (PPI) is a physically based vegetation index, developed for improving the monitoring of the vegetation growth cycle. The PPI index values, with 5-day satellite revisit cycle, are first used in a function fitting to derive the PPI Seasonal Trajectories, which is a filtered time series with regular 10-day time step. From these Seasonal Trajectories, a suite of 13 Vegetation Phenology and Productivity (VPP) parameters are then computed and provided, for up to two seasons each year. The Total Productivity is one of the 13 parameters. The full list is available in the table 3 of the Product User Manual in the below link section. A complementary quality indicator (QFLAG) provides a confidence level, that is described in table 4 of the same manual. The TPROD dataset is made available as raster files with 10 x 10m and 100 x 100m resolutions, in ETRS89-LAEA projection corresponding to the HRL grid, for those tiles that cover the EEA38 countries and the United Kingdom and for two seasons in each year from 2017 onwards. It is updated in the first quarter of each year.
总生产力(Total Productivity,TPROD)作为植被物候与生产力(Vegetation Phenology and Productivity,VPP)参数之一,是哥白尼陆地监测服务(Copernicus Land Monitoring Service,CLMS)旗下泛欧洲高分辨率植被物候与生产力(High Resolution Vegetation Phenology and Productivity,HR-VPP)组分的产出数据产品。总生产力(TPROD)又称大积分值,指生长季积分,其计算方式为生长季起始日期(SOSD)与生长季结束日期(EOSD)范围内所有单日植物物候指数(Plant Phenology Index,PPI)数值的累加和。植物物候指数(PPI)是一种基于物理机制的植被指数,专为优化植被生长周期监测工作而研发。该指数的卫星重访周期为5天,其数值首先被应用于函数拟合流程,以推导得到PPI季节轨迹——这是一类经滤波处理、时间步长固定为10天的时序序列。基于上述季节轨迹,可计算并输出一套共计13种植被物候与生产力(VPP)参数,每年最多可生成两个生长季的参数结果,总生产力便是这13项参数之一。完整参数列表可参见下文链接章节中《产品用户手册》的表3。配套的质量指示因子(Quality Flag,QFLAG)可提供数据置信度水平,相关说明详见该手册的表4。TPROD数据集以栅格文件形式发布,分辨率包含10×10米与100×100米两种,采用匹配高分辨率栅格(HRL)网格的ETRS89-LAEA投影,覆盖欧洲经济区38国(EEA38)与英国的相关图幅;自2017年起,每年可提供两个生长季的数据,并于每年第一季度完成更新。
