- Swedish Report to ILWS

## Swedish ILWS in short

- 	**Swedish scientist are active in a range of ILWS-related studies, involving observations from both space and the ground (Eiscat). The studies address the following:**
- The Earth’s upper atmosphere
- The Earth’s Ionosphere and Magnetosphere
- The environments of solar system bodies
- Space weather, including the Sun itself

## The ”national” satellite programme

| Satellite | Objective | Operation |
| --- | --- | --- |
| Viking | Investigation of plasma physics and the auroral phenomena | 1986-1987 |
| Freja | High-resolution measurements in the upper ionosphere and lower magnetosphere (co-operation: Germany) | 1992-1996 |
| Astrid-1 | Investigation of near plasma with emphasis on neutral particle phenomena | 1995 |
| Astrid-2 | High-resolution measurements of electrical and magnetic fields in the auroral region | 1998/1999 |
| Munin | Equipped with instruments for auroral studies | 2000 |
| Odin | Combined astronomy and aeronomy mission (together with France, Canada and Finland) | 2001 - ... |
| PRISMA | Technology demonstration for Formation Flying.
Tests also a MEMS-based particle detector. Together with France, Germany and Denmark | 2008(9) |
| PREMIER | Proposal to ESA for studies of the Earth’s atmosphere.
Assessment study on-going. Will, if successful, include a Swedish radiometer. UK PI. | 2014 (?) -... |
