Overview:

ASUR was involved in the NASA activities in winter 1999/2000. Funded by the European Union ASUR was operated on board the NASA DC-8 research aircraft. A schedule of all NASA activities during SOLVE is given in the plot below. Shown are the periods with the aircraft based in Kiruna (Sweden). In addition, the high altitude aircraft ER-2 operated in mid and late winter and four in-situ and remote sensing payloads (OMS) were launched on large balloons. For simplification the bars indicate the first three days after flight readyness. However, due the weather conditions the flights of the OMS remote gondola were delayed to 3 December 1999 and 15 March 2000, respectively. Click here for a detailed overview over all flights with ASUR during the SOLVE campaign.

Data:

The data of ASUR's operational products are open to the public. Vertical profiles of ozone, HCl, ClO, HNO₃, and N₂O measured by ASUR during the SOLVE campaign are available for download on NASA's SOLVE data server. Please contact the ASUR group (e-mail: asur@iup.physik.uni-bremen.de) if you want to use these data for your scientific work.

Further the plots of the near-realtime analysis perfomed during the campaign have been put on the web to provide an overview over the measured quantities. The plots are given as encapsulated postscript files and show preliminary volume mixing ratios of different trace gases along the flight path.

Co-operations:

The SOLVE campaign is carried out in cooperation with the European Theseo 2000 program which also finances the ASUR campaign activities in 2000. Informations about the other activities supported by this program can be found on the Theseo 2000 homepage and on the homepage of the European Ozone Research Coordination Unit. Within Theseo 2000, the EuroSOLVE project has the objective to create the best possible synergy between Theseo 2000 and SOLVE.
