Net primary productivity (NPP) and associated parameters for the U.S. outer continental shelf waters, 1998-2009 (NODC Accession 0071184)

This accession consists of monthly net primary productivity (NPP) estimates for 1998-2009 derived from the Vertically Generalized Production Model (VGPM) for the 26 Outer Continental Shelf planning areas in the United States, produced by CSA International, Inc. (CSA) under contract to the U.S. Department of the Interior, Bureau of Ocean Energy Management, Regulation and Enforcement. The NPP data are provided as GeoTIFF files depicting global gridded monthly NPP estimates. Summary NPP statistics for each of the 26 planning areas are also provided as separate ASCII text files. Input data sets used in the VGPM were also provided by CSA and present in this accession. These input data sets include global monthly sea surface temperature from the AVHRR Pathfinder Version 5.0 data set, global photosynthetically available radiation (par) and chlorophyll-a concentration data from the SeaWiFS and MODIS instruments, and global climatological monthly mean photoperiod data. These input data sets are provided in HDF4, with the exception of the photoperiod data which is provided in binary format.本数据集包含1998-2009年的月度净初级生产力（Net Primary Productivity, NPP）估算结果，该结果基于垂直广义生产模型（Vertically Generalized Production Model, VGPM）生成，覆盖美国26个外大陆架规划区域。本数据集由CSA国际公司（CSA International, Inc., CSA）受美国内政部海洋能源管理、监管和执法局委托制作。 NPP数据以GeoTIFF格式文件提供，用于展示全球网格化月度NPP估算结果。此外还为26个规划区域分别提供了ASCII文本格式的NPP汇总统计数据。 本数据集同时包含VGPM模型所使用的输入数据集，这些输入数据同样由CSA国际公司提供。输入数据集涵盖：来自先进甚高分辨率辐射计（AVHRR）探路者V5.0数据集的全球月度海表温度数据；来自海洋宽视场传感器（SeaWiFS）与中分辨率成像光谱仪（MODIS）的全球光合有效辐射（Photosynthetically Available Radiation, PAR）及叶绿素a浓度数据；以及全球气候学月度平均光周期数据。上述输入数据除光周期数据采用二进制格式存储外，其余均以HDF4格式提供。
