We use our mutual information (MI) forecasts between candidate observation locations and future regional field or variables of interest (target or verification field/variables) to predict the most informative future data locations. We use our MIT MSEAS ensemble forecast to predict these MI fields.
For the MI fields that we show in the table below, the goal is to predict the location of candidate future glider observations (temperature and salinity profiles) on different days (00Z Apr 30 to 00Z May 5) that are the most informative about the target σT, on 00Z May 6, 2025, in the region of the forecast LC and its uncertainty.
- The candidate glider observations at each location in the domain occur at the times indicated in the headers of each MI plot. These glider temperature (T) and salinity (S) profiles are assumed taken at the 0m, 50m, 150m, 300m and 500m depths, unless these depths are below the topography, in which case the depths are equally redistributed.
- The target (verification) variables are the σT fields in the region of the forecast LC and its uncertainty at 00Z on May 6, 2025. These fields are defined by σT profiles at all the locations shown by green stars taken together, at 00Z on May 6, 2025, at 150m, 300m, and 500m depths (in the region of the forecast LC and its uncertainty).
The locations with highest MI (bright yellow) on each day indicate where glider T and S profile observations are predicted to be most informative about the LC and its uncertainty at 00Z on May 6, 2025. The results indicate that the glider T/S profiles the most informative about the sigma-T field in the forecast LC region and its uncertainty are near the center of the LC (especially at depth).
