Solar Wind Utility
Contents:
Overview
This PlugIn calculates various useful solar wind parameters such as energy input,
dynamic pressure and magnetopause standoff distance. Note that data from the ISTP
ACE mission has a faulty Frame attribute. Edit this manually or set
to vector>gse_xyz.
Input data
Required inputs are :
- B-imf - vector time series with IMF maqgnetic field
- solar wind bulk velocity - vector time series
- plasma desity - scalar time series or constant
- time interval
- time shift - optional time shift
Outputs
Output quantities are:
- solar wind bulk speed - shifted version of input plasma velocity
- epsilon - the Akasofu Epsilon parameter - input energy to the magnetosphere
- energy - accumulated input energy - epsilon integrated over time
- pdyn - solar wind dynamic pressure
- Rst - magnetopaus standoff distance - approximate distance to magnetopause subsolar point
Bugs/Caveats
Note that ACE data has empty Frame attribute in the CFD files. Edit manually.
