Marine picophytoplankton is the most abundant photosynthetic group on Earth, however it is still underrepresented in dynamic ecosystem models. Major constraints for understanding its role in the ecosystem at a global scale are sparse data and lack of a baseline description of its distribution. Here we present three datasets to assess the global abundance of the principal groups of picophytoplankton, Prochlorococcus, Synechococcus and picoeukaryotic phytoplankton: i) a compilation of 109,076 field observations with ancillary environmental data, ii) a global monthly climatology of 1-degree grids from 0 to 200 m, and iii) four climate scenarios projections, from the Coupled Model Intercomparison Project 5, spanning years 1901 to 2100. Together this set of observational and modelled data can improve our understanding of the role of picophytoplankton in the global ecosystem.
