Abstract：

Marine net primary production (MNPP) is an index that measures the photosynthesis capacity of marine phytoplankton. The standardized anomaly dataset of global marine net primary productivity (1998-2019) was developed based on the monthly NPP data of the SeaWiFS.R2014 from January 1998 to December 2002 and the MODIS.R2018 from January 2003 to December 2019. The seasons were divided based on the three months composite March to May, June to August, September to November and December to February. The data results show that the abnormal change pattern of marine primary productivity is closely related to the evolution of ENSO events. The dataset includes the following global data from 1998 to 2019: (1) yearly NPP; (2) 3 months composite NPP; (3) yearly NPP standardized anomaly data; (4) 3 months composite NPP standardized anomaly data; and (5) monthly NPP standardized anomaly data. The spatial resolution of the data is 9 km x 9 km. The dataset is archived in HDF4 format, consists of 484 data files with data size of 16.82 GB (compressed into 16 data files with 4.81 GB).
