The following sensors are installed and monitored at the weather station of the University of Applied Sciences Berlin (HTW Berlin).
Highly accurate solar, wind and environmental data is gathered at the weather station at the University of applied science Berlin (HTW Berlin) in the South-East of Berlin. The weather station has overall 15 sensors, which were readout with a sample rate of 1 s and the measurement is securely stored in a redundant data archive. Furthermore an uninterruptible power supply (ups) guaranties high uptime of the data logger. All sensors were calibrated in summer 2016. This weather station was realized as part of the research project "PV2City" (ID 1048-BS-0). This project is funded by the Berlin program for sustainable development (BENE) which is co-financed by the European Union through the European Regional Development Fund (ERDF) and the state of Berlin.
The global irradiance is measured with different technologies and different orientation above the edge of the roof. Besides basic silicon sensors also highly accurate and fast responding pyranometer were mounted to measure without any shading. The comparison of different sensor types is available for horizontal orientation and a 35° inclined plane facing South. Furthermore the measurement for 35° inclined SMP21 sensors facing East and West can be evaluated.
Besides the measurement of the global irradiance, the direct-normal and diffuse horizontal components are also measured accurately. They were obtained though a solar tracker at the foot of the weather pole. Unfortunately the trackers pyrheliometer is slightly shadowed in winter morning hours.
The installed wind sensors measure the wind from all directions freely on a pole above the edge of the roof.
The weather station is mounted on the roof of the Building G at HTW Berlin located in the South-East of Berlin.

Since 2010 weather data is available at the HTW campus. Until 2016, when the station was generally revised, the sensor portfolio was continuously extended. Therefore a few sensors has long-term data reaching backward from September 2016 to October 2010. In favor of a highly accurate irradiation measurement the illuminance sensor and the rainfall sensor were not brought back into service after 2016. It should be taken into account that those long-term measurement is only available as 1 min mean values.
The time series of the long-term measurement is also available on this page. Nevertheless keep in mind the slightly different hardware configuration.
