International Solar Terrestrial Physics Program

Project Description

The primary science objectives of the ISTP Science Initiative are as follows: Determining structure and dynamics in the solar interior and their role in driving solar activity.

Identifying processes responsible for heating the solar corona and its acceleration outward as the solar wind. Determining the flow of mass, momentum and energy through geospace. Gaining a better understanding of the turbulent plasma phenomena that mediate the flow of energy through geospace. Implementing a systematic approach to the development of the first global solar-terrestrial model, which will lead to a better understanding of the chain of cause-effect relationships that begins with solar activity and ends with the deposition of energy in the upper atmosphere.

The ISTP Science Initiative uses simultaneous and closely coordinated measurements from GEOTAIL, WIND, POLAR, SOHO and Cluster. These measurements of the key regions of geospace will be supplemented by data from Equatorial missions and ground-based investigations. The Equatorial missions include: the Geosynchronous Operational Environmental Spacecraft ( GOES) Program of the National Oceanic and Atmospheric Administration (NOAA) and the Los Alamos National Laboratory ( LANL) spacecraft from the Department of Energy (DOE). The ground-based investigations include:

SUPER-DARN - Dual Auroral Radar Network
CANOPUS - Canadian Auroral Network for the Origin of Plasmas in Earth's Neighborhood Program Unified Study
SESAME - Satellite Experiments Simultaneous with Antarctic Measurements
Sondrestromfjord Incoherent Scatter Radar
