Atmospheric Research

The Swedish National Space Board is supporting atmospheric research that utilizes high altitude balloons, sounding rockets, and satellites. 

Satellite observations

The satellite Odin, in orbit since February 2001 with a 1.1-meter submillimeter telescope, is making regular limb-scanning observations of the upper atmosphere (20-100 km).  Three-dimensional maps of abundances of several trace gases, in particular those important to ozone depletion, are extracted from the observations.

Observations from Sounding Rockets and Balloons

Is there an infall of microscopic particles from space and do such particles linger at high altitudes in the Earth's atmosphere for long periods?  This was the main question for the sounding rocket project Magic, which was launched from Esrange in january 2005 (see MISU_Magic).
In December 2001 the sounding rocket Hygrosonde 2 was launched from Esrange to validate observations from Odin (see MISU Hygrosonde 2).  Balloons from France and Sweden were also launched to validate Odin data at lower altitudes.

Two sounding rockets, NLTE (Non-Local Thermodynamic Equilibrium), were launched from Esrange in March 1998. The aim was to study the heat budget and effects of non-local thermodynamic equilibrium in the upper mesosphere and lower thermosphere.

A series of balloons called Skerries have been launched from Esrange with the aim to study climate effects in the stratosphere. Concentrations of CFCs, water vapour, ozone, etc. have been measured regularly.  For further information, seeIRF Climatology
