Models

SWPC researchers and forecasters utilize a variety of models  to better understand the current state of the space weather environment, as well as to project future events.  Many of these models have been developed in house at SWPC, while other models have been developed by partners and are shared by the space weather community.

Models, in Space Weather, are mathematical descriptions of the conditions of the space environment, based on statistical analysis of past and current observations of the space environment. Models that indicate current conditions are called Nowcasts, while other models provide information about future events, aiding forecasters in their predictions.
