| Abstract | High frequency (HF) radio communication, relied on by the aviation industry, is sensitive to space weather and would benefit from an operational service that warns the industry when impacts can be
expected. Recognizing this need, the International Civil Aviation Organization (ICAO) initiated the development of a space weather advisory service that began operation on November 8, 2019. This article describes two space weather phenomena,
absorption and post-storm maximum usable frequency (MUF) depression, which can severely degrade HF communication. |
| Summary | (Plain Language Summary, not published)
Space weather refers to the dynamic conditions on the Sun and in the space environment, in particular, in the near-Earth environment, that can affect
critical infrastructure. NRCan operates the Canadian Space Weather Forecast Centre and conducts research into space weather effects on power systems, pipelines, radio communications and GNSS positioning to help Canadian industry understand and
mitigate the effects of space weather. This article describes space weather impacts to high frequency radio communication relied on by the aviation industry. |
