This dataset describes the estimates of gridded nitrogen fixation from various sources globally. The global gridded datasets of BNF generated here are available in the ScienceBase repository (https://www.sciencebase.gov/catalog/item/66a97480d34e07a119db3a37). The underlying BNF rate dataset in natural terrestrial biomes is also available in the ScienceBase repository (https://www.sciencebase.gov/catalog/item/66a97365d34e07a119db3a30). All other data are available from the databases cited or are in the main text or the supplementary materials. The links will be made active upon acceptance. Portions of this dataset are inaccessible because: See link above. They can be accessed through the following means: See link above. Format: See link above.
