As you know, ex-hurricane Ophelia arrived on Monday to Ireland. Following the advise of the Irish meteorological service, we stayed at home, but… we didn’t have electricity nor water! Want to know what we did? Keep reading and you may find delicious surprises!
Research aircrafts do not usually fly straight to a point and back, as you would expect for instance a passenger plane to go. Observing flight tracks of such a plane give very funny patterns, hence. See for yourself.
To prepare for a research flight takes quite some time and involves many people. It starts in general 3-4 days in advance when some scientist sit together over the forecasts and think about the most interesting atmospheric situations to probe. Two days in advance they hand over a preliminary flight plan to the HALO flight operations team. These colleagues from the German Aerospace Center (DLR) talk to Air Traffic Control (ATC). A day in advance this preliminary flight plan is updated with the recent forecast.
Yesterday evening at 19:28 (German time), HALO with the WISE instruments onboard landed at Shannon airport. The flight from the DLR site in Oberpfaffenhofen was used not only as a transfer but to investigate some of the WISE scientific goals on the way. Therefore instead of going to Shannon directly, the transfer was enlonged to a 10-hour research flight passing by Southern Norway, up north beyond the polar circle and coming down over Iceland. Eventually, a hexagonal flight pattern for tomographic evaluation was added above the North Atlantic crossing over from Iceland to Ireland.
Just about a month after the successful StratoClim campaign is over, there is the next measurement campaign with IEK-7 participation “taking off” at the moment… so welcome to WISE! During the next 5 weeks, Irene, Isabell, Lukas and me (Conny) will keep you posted here in the blog about what is going on with our instruments on-board of HALO.
