ROMS Diagnostics: Analysis Compared to Observations

These figures show the root mean square error (RMSE) of the model and observations in space, time, and/or depth for a selection of variables and instrument types.


Select Region:

The figures below show the RMSE in space of sea surface temperature for the model and OSTIA or MODIS. The panels on the left show the RMSE figures prior to model data assimilation and on the right, after model data assimilation. If available, the RMSE of surface velocity for the model and the high frequency radios are shown below.


The figures below show the RMSE in time for the sea surface height, the sea surface temperature, and the high-frequency radio. Note that if the type of data is not used in the model assimilation, it will not be shown below. The solid lines with crosses represent the RMSE in time of the model prior to data assimilation and the observations while the dashed lines with circles are the RMSE of the model after data assimilation and the observations.


If available, the two figures below show the temperature and salinity RMSE in depth. The RMSE between the model and observations prior to model assimilation is shown in blue and the RMSE after model assimilation is in red.
