Your initial search may return hundreds or even thousands of layers. Scanning all these layers to find the most relevant one could take a long time. You need to refine your search.
Refine your search to receive only layers that include sea surface temperature.
layers = wmsfind('temperature'); sst = layers.refine('sea surface');
Refine the search again to include only layers that contain the term "global."
global_sst = sst.refine('global');
You can search for layers in a specific geographic area.
First, find hurricane layers.
layers = wmsfind('hurricane');
Refine your search by selecting layers that are in the western hemisphere.
western_hemisphere = layers.refineLimits ... ('Latlim',[-90 90], 'Lonlim', [-180 0]);
Refine again to include only layers in the western hemisphere that include temperature data.
temp_and_west = western_hemisphere.refine('temperature');
