Monthly average Global depth-integrated oceanic N₂ fixation rates Dataset (September 1990 - December 2024)

This dataset is a satellite-derived global monthly product of depth-integrated oceanic N₂ fixation rates. The temporal coverage spans from September 1997 to December 2024. Each data file contains N₂ fixation rates (units: µmol N m⁻² d⁻¹) together with corresponding longitude and latitude information, at a spatial resolution of 0.25°. Non-ocean and invalid pixels are assigned as NaN. The data are provided in NetCDF (Network Common Data Form) format.Naming rules: Data files are named following the conventioncategory_YYYYMM_resolution.nc.For example: N2_fixation_199709_025deg.nc, where YYYYMM denotes the year and month, and 025deg indicates a spatial resolution of 0.25°.
