Net Photosynthesis (MOD17A2H) in kg C/m² for Selenga river basin (the Buryat Republic and Mongolia), monthly (May-October), phenology season (May-October) annual max, sum 500-m composites from 2000 to 2020

Net Photosynthesis (MOD17A2H) in kg C/m² for Selenga river basin (the Buryat Republic and Mongolia), monthly (May-October), phenology season (May-October) annual max, sum 500-m composites from 2000 to 2020. The product is based on aggregates from MOD17A2H. The MOD17A2H Version 6 Gross Primary Productivity (GPP) product is a cumulative 8-day composite of values with 500 meter (m) pixel size based on the radiation use efficiency concept that can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. The data product includes information about GPP and Net Photosynthesis (PSN). The PSN band values are the GPP less the Maintenance Respiration (MR). https://lpdaac.usgs.gov/products/mod17a2hv006/ .

本数据集涵盖2000年至2020年色楞格河流域（布里亚特共和国与蒙古国境内）的净光合速率（Net Photosynthesis, PSN）数据，单位为千克碳/平方米（kg C/m²），为500米分辨率合成产品，包含逐月（5月至10月）以及物候季（5月至10月）的年度最大值与总和值。该数据集基于MOD17A2H产品的聚合数据生成。MOD17A2H版本6总初级生产力（Gross Primary Productivity, GPP）产品是以辐射利用效率理论为依据生成的累积8天合成数据，像素分辨率为500米，可作为输入数据用于构建计算陆地能量、碳循环、水循环过程以及植被生物地球化学循环的相关模型。该数据产品包含总初级生产力与净光合速率两类信息，其中净光合速率波段的数值为总初级生产力减去维持呼吸（Maintenance Respiration, MR）后的结果。更多详情可访问：https://lpdaac.usgs.gov/products/mod17a2hv006/ ，如需进一步咨询可联系Alexander Prishchepov，邮箱为[e-mail]、[e-mail]。
