June 22, End of the semi-blind intercomparison study today. Results presented and discussed at a joint WebEx meeting with ESA. All instruments are working fine at the Sodankylä campaign site.


July 6 - 8, Site visit by Christof Petri from University of Bremen. He worked on the instrumental alignment for the Vertex70. The alignment was successful and lead to a better instrumental lineshape for the Vertex70. View pictures from the visit here:


August 8, Project WebEx meeting organized by ESA. Recent results were shown and discussed. All instruments are working normally except LHR, it had some problem and was not operational for 3 weeks. The problem was solved remotely by RAL, so no site visit was necessary. The instrument will be online soon after few checks.
