Frank: Measurements were taken at the same time, almost at the same place (the exact location can be found at practical-issues). For comparison reasons, the range above ground was transferred to range above sea level. The NetCDF values of the station altitude were checked and correspond to the ones provided at practical-issues.

* Different algorithms together with different definitions of cloud base height lead to different CBH values

* Campbell profiles have a bias of 1-2 bins (10-20 m). I have seen that bias in many profiles.
