Local weather monitoring network to support disaster control on site

OVERVIEW: PUBLIC OBSERVATORY AND WEATHER NETWORK HAGEN

The Arbeitsgemeinschaft Volkssternwarte Hagen e.V. (Hagen Public Observatory Association) is a volunteer-run observatory that is primarily available to members and interested citizens. You can find more information at www.sternwarte-hagen.de.

The Hagen Weather Network is a working group within the association that specializes in meteorology. Learn more about its work at www.wetternetz-hagen.de.

There are now 15 weather stations operating in different areas and at different altitudes within the city. Two of the main objectives are to record the local climate and the effects of climate change more accurately, and to provide the population and authorities with local measurement data in the event of extreme weather conditions, such as heavy rain and storms.  

Special challenges

1. Prevent icing of the sensors

The observatory's sensors were often iced up in winter, especially in exposed areas. This caused the wind sensors to provide incorrect readings or fail completely.

2. Improve the reliability of weather stations 

Only a reliable, responsive weather measurement network can indicate where heavy rain is occurring in order to support local disaster control with short-term forecasts. The entire network of weather stations must provide accurate measurements in real time and detect sensor anomalies itself in order to maintain data integrity.

Requirement

Precipitation in the Hagen urban area varies greatly. A dense local measurement network has already helped to respond more effectively to flooding events. An additional precipitation sensor was needed to reliably record the exact amounts of precipitation, even in winter, and to support operational planning.

Solution

The Hagen Public Observatory has the heated rain[e]one precipitation sensor and the Ser[LOG] data logger MeteoWare-CS software in operation at several locations in order to further consolidate and strengthen the local weather measurement network.

Ser[LOG] Data Logger

The Ser[LOG] collects your weather data (wind, precipitation, air temperature, relative humidity, air pressure, and radiation) in one place and provides real-time visualization. The Ser[LOG] Commander management app gives you maximum freedom to customize your measurement tasks.

Overview:

• Collect and process up to 60 measured values with Modbus RTU
• Up to 32 Modbus TCP connections with sensors from other manufacturers
• Alarm system for 10 warning channels using built-in and external relays (e-mail, SMS)
• Extensive sensor library
• Formulary and free formula parser
• Interference-proof due to high-quality, shielded aluminum housing
• User-friendly with free access to all connections and controls
