  1. Campaign data for parameterization tests: Examples from MAP‘99 VERTIKATOR’02, AWIATOR‘03 Hans Volkert, Thorsten Fehr, Christoph Kiemle, Oliver Reitebuch, Arnold Tafferner and Martin Weißmann Institut für Physik der Atmosphäre DLR Oberpfaffenhofen, D Evelyne Richard Laboratoire d‘Aérologie, CNRS & Université Paul Sabatier Toulouse, F

  2. Textbook knowledge: “Whenever possible, parameterizations should … be quantitatively validated against observations“ (Peixoto & Oort 1991) High resolution … … simulation models need special data, e.g from dedicated field campaigns Which variables and processes? here: wind, boundary layer, precipitation microphysics

  3. The campaigns MAP-SOP 1999 Mesoscale Alpine Programme Special Observing Period „Weather and Alps“ 7 Sept. – 15 Nov 1999 cf.
