Hello P.Romero,<br>
<br>
You should use 2-meter temperature from GFS to represent the near-surface air temperature. Over water, the surface (skin) temperature in GFS is equal to the SST that is being used in GFS. Over land, the skin temperature is calculated from the surface energy budget, while the 2-meter temperature is a simulated shelter temperature, so it is a better representation of the near-surface air temperature.<br>
