Lancaster University's IRIS imaging riometer in northern Finland has collected ionospheric absorption data since September 2, 1994. The system operates at 38.2 MHz and produces an array of 49 narrow beams with a basic scanning interval of one second. Data and plots can be requested via an automated facility, and the system is funded by the UK's Science and Technology Facilities Council.
Use Cases
- Analyzing ionospheric absorption events based on the 49-beam imaging riometer data.
- Studying space weather impacts on radio communications based on the 38.2 MHz frequency measurements.
- Modeling quiet day curves for baseline comparisons using the described algorithm.
- Investigating scintillation patterns based on the provided IRIS utilities.
- Correlating geophysical events with high-latitude ionospheric data from the Kilpisjärvi station.
Strengths
- Continuous operation since a specific start date: September 2, 1994.
- Provides data from a 49-beam imaging riometer array for detailed spatial analysis.
- Operates at a defined frequency (38.2 MHz) with a one-second scanning interval.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
