SST values in continental region

[Aurora_LagosD]

Hello WRF community,

I am running simulations with and without updating the sea surface temperature. When I plot the SST variable from the wrfout with and without SST updates, it has positive values over the continental region. I think it should be NaN or 0 values. Am I doing something wrong?

Here I attach the namelist.input (sst_update = 0), the landmask and a plot with SST values.

SST over land could be SKINTEMP or TSK. wrfout files won't allow NaN values.
