MISST SSTs

Sea surface temperature is one of the most important variables related to the global ocean-atmosphere system. It is a key indicator for climate change and is widely applied to studies of upper ocean processes, to air-sea heat exchange, and as a boundary condition for numerical weather prediction. The importance of SST to accurate weather forecasting of both severe events and daily weather has been increasingly recognized over the past several years. Multiple operational SST products are currently available and are in widespread use. Despite the well-established state of SST measurements, there are still significant weaknesses in the existing products.

The MISST project is making a direct U.S. contribution to the Global Ocean Data Assimilation Experiment (GODAE) by working within the GODAE High-Resolution SST Pilot Project (GHRSST-PP), initiated by the international GODAE steering team, to coordinate the production of a new generation high-resolution SST.

Impact Studies

The primary user communities and their needs addressed by MISST are:

National Hurricane Center: NRT high-resolution bulk SST for hurricane intensity forecasting since the current SST product does not adequately resolve some SST features having a direct impact on storm strength.

US Navy: NRT high-resolution skin and bulk SST observations with error statistics plus bias and diurnal cycle corrections for assimilation into ocean and atmosphere forecast models at a variety of time and space scales .

NOAA NCEP: NRT high-resolution skin and bulk SST for operational forecasting, in particular both mesoscale NWP and the marine forecaster, to aid in adjusting wind and wave forecasts at the ocean-atmosphere boundary since stability effects currently are not adequately addressed in the numerical weather models.

GODAE: high-resolution bulk SST (at least 10 km, daily, global) for assimilation into ocean forecast models.
