Note that we only offer a subset of the data (see Parameters further down). A more complete list of measured and calculated parameters from the Hamburg weather mast can be found here.
Since 1967 the Meteorological Institute of the University of Hamburg operates a scientific, meteorological measuring site in Billwerder, a suburb of Hamburg, Germany. It is located on an area of the NDR (the North German Broadcasting Company, 53° 31′ 09.0″ N, 10° 06′ 10.3″ E) and consists of devices mounted at a 300 m tall broadcasting mast and a smaller 10 m tall mast owned by the MI nearby on a meadow. Additionally, several ground-based devices are installed outside the operator's hut beneath the tall mast. In 1994 completely new equipment was installed, and since 1995 measurements run almost continuously until today (data availability table (pdf, German)).
At the 300 m mast wind speed and direction, air temperature and humidity have been measured by several devices at altitudes of 10, 50, (70) 110, 175 and 250 m (since 2010 also 280 m) allowing atmospheric boundary layer studies. A list of measured and calculated values is given here (pdf, German). You get a detailed description about the data here (pdf, German).
Most of the sensors sample data every minute. We do not offer these original data. Available via ICDC are hourly and daily mean values. If you require data at finer temporal resolution please contact Ingo Lange or Felix Ament. You can learn more about the Hamburg weather mast and take a glimpse at the actually measured values if you click here.
Since 2015 you can get even more information via Wetternetz Hamburg(Facebook). Here you are informed about the Hamburg boundary layer measurement tower, the PATTERN rain radar and a measurement network for city climatology HUSCO.
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. The following list gives some information about the sensor accuracies:
