Blue screen of Death …

You will agree with me there is nothing more infuriating than working on a computer and suddenly the blue screen appears, leading to a restart… The infamous “Blue screen of Death”… Most people (including me) are extremely outraged by this and their rage frequently results in a ferocious shout, a slap on the desk or even a kick aimed at the computer box. Now imagine this, except this computer, is the ‘brain’ of your instrument that is worth about 1 000 000 Euros AND has data of 3 flights which you hope to use in your PhD… Need I say more!

Follow the air and see what it is doing

by  | 9. October 2017

One major goal in the WISE campaign is to follow the time evolution of air masses in the UTLS (upper troposphere-lower stratosphere) and to see how they are affected by tropopheric-stratospheric exchange. The latest (and upcoming) research flights are planned to provide an idea of exacty this time evolution. Flight 10 last Saturday was targeting a feature in the West-Atlantic with the plan to probe the same air again in later flights. At the moment, HALO is on its way to catch it now, two days later close to the Norwegian border.

Nice things to see from a plane

by  | 7. October 2017

There are some very nice things you can spot from a plane. Not only clouds and the ant farms that actually are cities but also atmospheric phenomena. I have seen for the first time a “Glory”  on my way to Ireland. On top, a colleague (Peter Hoor from the Johannes Gutenberg University Mainz) took a very nice picture of so-called “Kelvin-Helmholtz instabilities” on a research flight with HALO last week. So I just wanted to show you the pictures here and give you a short explanation on what it is.

HALO has arrived in Shannon

by  | 19. September 2017

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.

Welcome to WISE! – Campaign No. 2 in 2017

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.
