The Karlsruhe Institute of Technology (KIT), Institute of Meteorology and Climate Research is operating a 200m tall weather tower since 1972 (see photography above). Additionally, standard meteorological parameters and near-surface radiative fluxes are measured.
At the tower measurements are carried out at altitudes of 2m, (10m), 20m, 30m, 40m, 50m, 60m, 80m, 100m, 130m, 160m, and 200m allowing atmospheric boundary layer studies. Measured parameters are wind speed and direction, air temperature and humidity; not all parameters are measured in all given altitudes, only for those altitudes given in bold font all parameters are available. A list of the parameters measured at the tower and the site in general is given here.
Most of the sensors sample data every minute. We do not offer these original data. Available via ICDC are daily mean values. If you require data at finer temporal resolution please contact Martin Kohler. You can learn more about the Karlsruhe weather tower and take a glimpse at the actually measured values if you click here.

The data set does not contain uncertainty estimates.
The majority of the data are direct measurements anyways so that the accuracy of the sensors is more important in this context. Still a quality control is and has been carried out with the data set.
Note that for the daily averages offered from this web portal about 50% of the measurements of one day needed to be available and of sufficient quality. Otherwise no daily average was computed.
A documentation about the different sensors and sensor types used is in preparation and foreseen to be available in 2014.
Note: In the precipitation data 0.0 mm means both: no precipitation occurred or precipitation occurred but its amount was below what can be measured.
