Solar wind velocity and corrections

Summary:

distribution of solar wind

Main Question or Discussion Point

Greetings,

how do
- the velocity distribution of the solar wind at 1 AU
- the velocity distribution of the solar wind in our line of sight
look like?

I have found the 400 Km/sec but no further information. Is it an average values? Is this radially on the sun the same?
Links with graphs are welcome.

Last but not least:
Does the solar wind velocity play a role in the spectroscopy measurements? How?

Thank you very much.
E.

The solar wind is highly variable, and variations in the solar wind can have a direct impact on the Earth's magnetosphere (and hence ionosphere). Did you do a google search? A 1-minute google search (solar wind velocity distribution site:.edu) yielded a lot of good stuff. For example, look at chapter 3 of the PhD dissertation by Steven Peter Joy:

If you want to see more actual data, NASA still posts data from the WIND spacecraft.
https://wind.nasa.gov/links.php
at the bottom of the page you will see links to WIND daily summary plots and WIND 27-day summary plots. They are 27 days because that is the rotation rate of the sun.
