Content and data sources
========================
This dataset contains gobal fields of dimethylsulfide (DMS) and dimethylsulfoniopropionate in the sea surface layer, estimated with different remote sensing algorithms.
It is based on ocean colour data publicly available at https://oceancolor.gsfc.nasa.gov/.
Monthly climatological data are provided at 9 km, 1 and 5 degree resolutions on lat-lon grids.
Different satellite products have been used for chlorophyll_a and euphotic layer depth, as indicated in the names of the files:

{Variable}_{PERIOD}_{algorithm}_{spatial resolution}_{chlorophyll product}_{euphotic layer product}.nc

{chlorophyll product}: CHL corresponds to OC4-CI, GSM to Garver-Siegel-Maritorena.
{euphotic layer product}: KD490 corresponds to diffuse attenuation coefficient at 490 nm, ZLEE correspond to Lee et al. algorithm.

Note that CHL is not used in VS07 although it appears in the file name.

Please check Galí et al. 2018 Biogeosciences for details.
