The DCP takes meteorlogical measurements every second and radiological measurements every minute. All data are averaged every 15 minutes. The gamma data are evaluated for quality assurance.
Information describing the station sensors is available in the instrumentation section.
The transmitted data are separated into two files. This happens when a station does not have a particular sensor, or when a transmission error occurs. Gamma radiation, barometric pressure, temperature, and humidity are measured and recorded. Wind data are recorded but are not checked for quality assurance and are not guaranteed. Additionally, rainfall and the number of minutes the station door was open are also measured at some stations.
