Read a G1SST file in the netcdf format provided by the ERDDAP server (see reference 1).




character value containing the name of a netcdf file containing G1SST data.


A g1sst object.


As noted in the documentation for the g1sst class, one must be aware of the incorporation of model simulations in the g1sst product. For example, the code presented below might lead one to believe that the mapped field represents observations, whereas in fact it can be verified by consulting reference 2 (clicking and unclicking the radio button to show just the data) that the field mostly derives from simulation.
