ExB Drift

Purpose:
The purpose of the ExB Drift project is to demonstrate that realistic, daytime, vertical ExB drift velocities can be obtained in the equatorial F-region using two ground-based magnetometers, one on the magnetic equator and the other 7 to 10 degrees away in dip latitude. The code provides daytime ExB drift velocities in the Peruvian longitude sector when the difference in the Horizontal H component, H is supplied by the ground-based magnetometers in Jicamarca (1 degree N dip latitude) and Piura (7 degrees N dip latitude), Peru.

Input:
  • llions.set
  • DOY.drifts
  • piuDDMMM.YYm
  • jicDDMMM.YYm

(where DOY = day of year, MMM = month, DD = day of month, and YY = year)

Output:
The output of the ExB Drift process is an ASCII file containing drfit values for every 5 minutes. There are 5 columns and 289 rows. The 5 columns are:
  • local time
  • ExB drift value
  • -9999 (Default value for the theoretical Ionospheric Forecast Model.)
  • 0 (Default value for the theoretical Ionospheric Forecast Model.)
  • -9999 (Default value for the theoretical Ionospheric Forecast Model.)
