Overview

• Status & Schedule• Brief overview LYRA/PROBA2 (shown previously)

• Brief overview PREMOS/PICRAD

• Application for Space Weather:

Now-cast and short-term forecast of ozone in the middle atmosphere

Summary (Status as of Antalya 27.-30. 3.06)

• SWAP (0.1 Hz) + LYRA (60 Hz) on PROBA2 provide the EUV equivalent in Europe of the NOAA SXI + GOES X-ray monitor 2007-2008

• SODISM + PREMOS on PICARD will continue in the near UV and visual 2008/2009-2011

Summary (Status as of today 23.5.07)

• SWAP (0.1 Hz) + LYRA (60 Hz) on PROBA2 provide the EUV equivalent in Europe of the NOAA SXI + GOES X-ray monitor 2008-2009

• SODISM + PREMOS on PICARD will continue in the near UV and visual 2009-2012
