Vsw: Vsw is the daily-averaged magnitude of the solar--wind velocity in GSM coordintates. The data were obtained from OMNIWeb. This data is based on measurements from both the WIND and ACE satellites. Related Links and Publications AR All Ap: This model and the data used to generate it was described in McPherron 1998, 1999. The model is a linear AR model that uses the 36 preceding daily-average values of Ap to predict Ap on a given day. The model was generated using all of the data described in these references (from the years 1932-1996). Related Links and Publications |
