As described in Neggers et al. 2012, the KNMI Parameterization Testbed (KPT) consists of two main
components: i) an archive of data streams and ii) an interactive graphical user interface (GUI) for the
visualization and intercomparison of these data streams.
The data streams include a wealth of observations, mainly for Cabauw, as well as model output.
Among the available Cabauw observations are measurements from a 213m high tower, all kind of
surface and radiation flux measurements, lidar data, cloudnet data etc. etc. Model data can be divided
in extractions for the Cabauw location from 3D model runs, LES runs (limited periods), as well as 1D
runs. The 1D runs mainly concern different flavours and experimental versions of the Harmonie model
and are driven by RACMO (Regional Climate Model) which provides the large scale forcing.
The graphical interface allows quick visualization of all data. At the externally accessible website,
testbed.knmi.nl, only prefabricated plots are available. Once some security issues are solved the full
interactive graphical user interface will become available also outside KNMI.
This paper mainly describes the presentation at the ASM in Helsingor 2015. More results from the
testbed will be presented in forthcoming papers
