attribute NC_GLOBAL history String Created with map_and_write_to_netcdf.R. Input data were 4km-resolution spring bloom metrics and annual average chlorophyll-a (chl-a) concentration per bin. Bloom metrics for each bin and year were derived from a shifted gaussian curve fitted to the time series of daily logged chl-a data within that bin. Chl-a data were taken from the POLY4 chl-a dataset which was generated using remote sensing reflectances (Rrs) from the OC-CCI multisensor product (www.oceancolour.org) and regionally-tuned coefficients, and subsequently gap-filled using DINEOF (https://github.com/aida-alvera/DINEOF).
