Earth's magnetosphere historical data

  1. May 14, 2012 #1

    Earlier this month, I was searching for trends/graphs on solar activity. I found some good sites which I cannot post due to me being a forum noob ;-)

    Now, I am looking for the equivalent except this time, in relation to earth's magnetosphere levels (strength)

    Does this exist ?

    Can anyone confirm how the earth's magnetic field is generally measured ?

    I've read a bit about the Dst, the K indices.

    Mapping of the magnetosphere was initiated by the US Navy in the 50's as they charted the ocean floor. NASA became increasingly involved since that time. For a review article see http://www-spof.gsfc.nasa.gov/Education/bh2_1.html
