  title: DTN Aviation Enhanced Flight Hazards (EFH) Space Weather API
  description: The DTN Aviation Enhanced Flight Hazards (EFH) API retrieves available turbulence (including Nowcast), icing, high ice water content (HIWC), thunderstorms, ozone, jet stream axis, space weather, and Quantitative Volcanic Ash (QVA) data.  Each data type has its own endpoint.  Filtering parameters allow to limit data requests in various ways, particularly in limiting the area for which to find data.

                    Biological: Radiation hazard avoidance recommended for astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk.
                    Satellite operations: Single-event upsets, noise in imaging systems, and slight reduction of efficiency in solar panel are likely.
                    Other systems: Degraded HF radio propagation through the polar regions and navigation position errors likely.

                    Biological: Unavoidable radiation hazard to astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk.
                    Satellite operations: May experience memory device problems and noise on imaging systems; star-tracker problems may cause orientation problems, and solar panel efficiency can be degraded.
                    Other systems: Blackout of HF radio communications through the polar regions and increased navigation errors over several days are likely.

                    Biological: Unavoidable high radiation hazard to astronauts on EVA (extra-vehicular activity); passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk.
                    Satellite operations: Satellites may be rendered useless, memory impacts can cause loss of control, may cause serious noise in image data, star-trackers may be unable to locate sources; permanent damage to solar panels possible.
                    Other systems: Complete blackout of HF (high frequency) communications possible through the polar regions, and position errors make navigation operations extremely difficult.
