QSAS Index 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.
