cops_nsod_imk: wind data from sodar and RASS-sodar run by FZK/IMK-TRO during COPS 2007

The two instuments were: SCINTEC Sodar (MFAS) at Igelsberg, located near a waste disposal site. The device measures wind vectors every ten minutes. Metek RASS-Sodar in Bad-Rotenfels, located near a sewage treatment plant. The vertical wind component in the netCDF-files has been set to stupid values due to quality check failure for this variable.
