The Mirrion 2 system collects ionosonde soundings from a worldwide collection of ground stations and makes the data available to the public.
Master Ionosonde Data Set (MIDS)
The MIDS is a complete set of data received or generated by Mirrion that also includes documentation and software.
Ionograms are recorded tracings of reflected high frequency radio pulses generated by an ionosonde. Read more at the Ionospheric Program at NCEI page.
HF Propagation Prediction
A global prediction map of the Maximum Useable Frequency (MUF) created using Mirrion 2 data by amateur radio operator KC2G.
The Latency Monitor provides visual metrics on the timeliness of ionosonde data products moving from worldwide stations through NCEI’s processing pipeline to data recipients.
Time history plot of the Number of STP files backlogged in the Mirrion data processing queues. Updated hourly.
Time series of select scaled characteristics for the past week, by station.
Global Map of Real-Time Data
Maps of stations that have sent data to Mirrion recently, typically within the last week. Images are updated daily at 12:00 a.m. UT.
Note the size of the circle is a subjective and qualitative opinion as to the quality of the data and the area of "coverage" for each sensor.
