## Class to Hold G1SST Satellite-model Data

### Description

G1SST is an acronym for global 1-km sea surface temperature, a product that combines satellite data with the model output. It is provided by the JPO ROMS (Regional Ocean Modelling System) modelling group. See the JPL website [1] to learn more about the data, and see the `read.g1sst` documentation for an example of downloading and plotting.

### Details

It is important not to regard G1SST data in the same category as, say, `amsr-class` data, because the two products differ greatly with respect to cloud cover. The satellite used by `amsr-class` has the ability to sense water temperature even if there is cloud cover, whereas `g1sst` fills in cloud gaps with model simulations. It can be helpful to consult [1] for a given time, clicking and then unclicking the radio button that turns off the model-based filling of cloud gaps.
