Age, not just refresh
A successful refresh does not mean the underlying report is new. Check observation, issue and validity times on the data itself.

Behind every card.
A source worth knowing.
Observations, forecasts and operational notices serve different purposes. Here is how they fit into TAFCast.
| Information | Source or method | What to check |
|---|---|---|
| METAR & TAF | NOAA / Aviation Weather Center, through the TAFCast backend. | Station identifier, observation or issue time, forecast validity and any missing report. |
| 24h wind outlook | Open-Meteo model guidance. | Model forecast time and units. Model guidance is not an aerodrome observation. |
| IPMA observations | Portuguese automatic weather stations, where available. | Station location, observation age and distance from the airfield. |
| Synthetic outlook | Regional model-based estimates for supported fields without official reporting stations. | Explicit SAO label, validity, completeness and regional coverage. |
| NOTAMs | FAA and Autorouter sources. | Notice validity, scope and official briefing. Lists may be filtered or incomplete. |
| Runway components | Calculated from available wind and runway heading data. | Source wind, units, runway information and calculation limits. Not runway-selection advice. |
| Website globe | Natural Earth land geometry and the local TAFCast airport and SAO catalogues. | A dot indicates a catalogue location, not a guarantee of current weather or SAO availability. |

Missing is not clear
No report, an empty NOTAM list or an unavailable field is not evidence of safe conditions. Verify with official sources.
