Copernicus Marine Service sample data

Description

This sample data contains monthly values (November and December 2010) of sea water potential temperature (thetao, degrees C) and sea surface height (zos, m) off northwest Mexico, 1/12 degree horizontal resolution (aprox. 9.26 km).

Details

Source data corresponds to Global Ocean Physical Reanalysis database (GLOBAL_REANALYSIS_PHY_001_030), and was downloaded from the link below, then imported with the read.cmems function. The selected area covers from 20 to 35 degrees of latitude North and from 119 to 104 degrees of longitude West. Potential temperature includes five depth levels (0.494, 9.573, 29.445, 92.326, 318.127).
