The H-ESC provides a number of different models to forecast the solar wind speed at Earth. These are based on a variety of inputs techniques such as physics based, use of empirical relations or assumptions on the persistence of conditions from the previous solar rotation or measured by satellites in other locations with solar system. Each model has its own characteristics and caveats that means it may work better or worse depending on current space weather conditions or has other advantages such as fast computation allowing many iteration, ensemble modelling. The SWFSC/E combined solar wind speed visualisation product provides a simplified, low-resolution, overview of the various model results in order to aid comparison of the different forecast solar wind speeds over the next few days. This is aimed at supporting the assessment, selection and use of these models.
The H-ESC archive provides snapshots taken every hour. Please visit the SWFSC/E web page for detailed product descriptions and the latest forecast comparison SWFSC/E
