CAL Coupling of Atmospheric Layers, a Research Training Network within the EU Framework V programme, involved institutes in seven European countries under the co-ordination of the Danish National Space Institute. The focus was the middle-atmospheric transient luminous events (TLEs), such as sprites, jets and elves. The Eurosprite campaigns still take place every year.
CUPP Centre for Underground Physics in Pyhäsalmi; international high energy physics project; the latest development out of our long-term activities in cosmic ray physics.
SERCHAM Solar energetic radiation and chemical aeronomy of the mesosphere was a project where the SIC model was extended to include GOES X-rays, applied in Eiscat and ionosonde studies of e.g. solar flares and a solar eclipse.
SPECIAL Space Processes and Electrical Changes Influencing Atmospheric Layers; a ESF Network for studying the interactions between space and weather with some emphasis on atmospheric electricity.
GUISDAP Grand Unified Incohrent Scatter Design and Analysis Package; a toolbox for planning and analysing incohrent scatter radar experiments; a spin-off of out involvement in the EISCAT Scientific Association.
