Mutual information forecasts for optimal adaptive sampling guidance

Analysis and Forecasts for 15 Jun 0000Z to 22 Jun 0000Z 2025, Issued 15 Jun 2025

Measuring T,S    Verifying against U,V

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 June 15 to 00Z June 22) that are the most informative about the target velocity, on 00Z June 23, 2025, 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 June 23, 2025.
