The Tomorrow.io REST Weather API provides aviation-related data fields.
Important notice about "Metar" and "MetarTaf" fields:
Our weather engine uses formal airports weather reports (METAR, TAF, ASOS, and other airport weather observations) and publish them on the timeline, allowing users to consume the data sources as a fluent synthetic feed. Using these fields can allow users to base automatic alerts and insights on the most relevant aviation-related weather source, under consideration that this data is an advisory only.
