About METAR & TAF 3D

METAR & TAF 3D is a live aviation weather service for pilots, dispatchers, flight schools and anyone who needs to know what the sky is doing at an airport right now and over the next two weeks. It decodes every reporting airport's METAR and TAF into plain language in eight languages, computes runway crosswind components, draws hourly meteograms and a three-dimensional cloud profile, and forecasts with a calibrated blend of the major global weather models. It is built and operated by Kalynda, a small aviation-software company in Dalaman, Türkiye.

Who we are

Kalynda Teknoloji Havacılık ve Turizm Limited Şirketi ("Kalynda") was founded in April 2026 by Serkan Arslan, a pilot and software engineer, to build tools that pilots actually use in the cockpit and the briefing room. METAR & TAF 3D is its first public product; the same team also builds flight-navigation and flight-tracking applications for general aviation. The company is registered in Türkiye (MERSIS 0493152313600001) at Söğütlüyurt Mah. İstiklal Cad. No: 57, 48770 Dalaman / Muğla, Türkiye, and is the data controller for this site under the GDPR and the Turkish KVKK — see the privacy notice.

Where the data comes from

  • Observations (METAR, SPECI) and aerodrome forecasts (TAF) are the official reports issued by national meteorological services and distributed through the ICAO/WMO network; we obtain them from NOAA's Aviation Weather Center and national services, and republish them decoded, unchanged in substance. We never invent, edit or "correct" an observation.
  • SIGMETs and AIRMETs come from the same official sources and are drawn on the map as issued.
  • Airport reference data — runways, headings, elevations, IATA codes, coordinates — is compiled from national AIPs and open aeronautical databases and checked against observations.
  • Numerical forecasts — winds aloft, temperature profiles, cloud layers, precipitation — are taken from the global models of ECMWF (IFS and AIFS), NOAA (GFS), DWD (ICON), Environment Canada (GEM), Météo-France (ARPEGE) and the UK Met Office, via Open-Meteo.
  • Rain radar (for signed-in members) is provided by RainViewer.

Every airport page shows the raw report exactly as received, next to our decoding, so that a reader can check our work. Every code in the raw report is explained with a reference to the standard it comes from — WMO No. 306, ICAO Annex 3, FAA FMH-1 or the national AIP.

How the forecast is made

No single weather model is right every day. The Kalynda model is not a new numerical model; it is a method for combining the seven global models above into one forecast and for measuring how good that forecast is. For each hour and each location it takes a robust weighted mean of the models' winds (outliers are down-weighted rather than discarded), and then adjusts the weights according to how closely each model has been matching the live METAR observations at the nearest stations over the preceding hours. The result is verified continuously: the forecast for each horizon is compared with the observation that later arrives, and the resulting error is published on the model page. We stop at 14 days because beyond that only one model retains meaningful skill, and we do not present a single model's tail as a consensus.

What is free and what is paid

The live map, every airport's flight category, the decoded METAR and TAF, the runway crosswind diagram and a 24-hour meteogram are free to use, with a daily limit of 15 lookups across 5 airports for visitors who are not signed in. Free pages carry advertising. Paid plans (Pilot and Pro) extend the forecast to 10 or 14 days and add the observation archive, trends, world rankings, per-model comparison, briefings, alerts, data export and the 3D profile; members see no advertising. Prices, terms and the refund policy are on the plans page and in the terms.

Editorial policy

The pilot guides are written by the people who build the site, from the primary standards and from operating experience, and are revised when a standard changes or a reader points out an error. Each guide carries its publication and revision dates. We do not publish sponsored content and advertising has no influence on what we write or decode.

Limitations

This site is a situational-awareness and educational tool. It is not an approved source for operational flight planning: use the official briefing service of your state, and the NOTAMs, for that. Observations can be late, stations can be unserviceable, and forecasts can be wrong — we show the age of every observation and the measured error of every forecast horizon so that you can judge for yourself.
