Monthly mean dataset of global phytoplankton taxonomic group concentrations (2002.7-2022.3)

This dataset is a satellite product of global monthly mean phytoplankton taxonomic group (PTG) chlorophyll-a concentrations, including chlorophytes (Chlor), diatoms (Diat), haptophytes (Hapt), cryptophytes (Crypt), and cyanobacteria (Cyan). The time coverage of the dataset is from July 2002 to March 2022. The data file includes PTG's chlorophyll-a concentration (unit: mg m-3), longitude, and latitude information, with a spatial resolution of 36 km. The values of non-water and invalid pixels are set to NaN. The data format is NetCDF (network common data form, nc). Naming rules: "data source identification_month and year_PTGs_data_production time.nc". Examples are as follows: MO_200207_PTGs_data_20220520.nc where "MO" refers to MODIS-Aqua data. "200207" represents July 2002. The data production time is expressed as "month, month, day day, year". "nc" is the suffix of the NetCDF data file. Each nc file contains six PTGs Chla concentrations (unit: mg m-3).
