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.
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.
