Abstract |
IAGA 2013, aout 2013, Merida, Mexique.
A great number of Space Weather applications rely on K-derived planetary geomagnetic indices. These indices, namely Kp/ap or Km/am (depending on the number of used subauroral geomagnetic stations) are therefore limited to the 3-hour time resolution of K indices. In addition, they do not represent the intrinsic spatial variations that result from the local time dependency of the solar wind/magnetosphere interaction.
We have defined new geomagnetic indices, based on the magnetic variations recorded in the am network of ground based observatories, with a better time resolution and/or a better spatial resolution. Using the root mean square of the horizontal magnetic variations, instead of the 3-hour K indices, we have calculated !m indices with different time resolution down to 15 minutes.
On another hand, the better spatial resolution is achieved by considering sector indices defined with respect to the Magnetic Local Time, the so called MLT sectorial indices. The properties of theses new indices will be presented. As an application, we will present their possible use in thermosphere modelling. We will also present how the !m index brings new information in the study of the dynamic of the magnetosphere and of the inner magnetosphere. |
