Abstract

The European Meteorological Aircraft Derived Data Center (EMADDC), see emaddc.com, processed aircraft surveillance data to derive wind speed, wind direction and temperature observations. This global dataset contains data provided by Met Office (source FlightRadar24) and other various sources, and is produced at regular intervals (5 minutes) with frequent updates and with less than a minute latency.

Supplemental information

Additional documentation can be found at emaddc.eu (https://emaddc.com/participate/data+users/default.aspx).

This represents one of three restricted EMADDC datasets:

  • The EMADDC MO Global Dataset, which includes observations generated using data provided by the MET Office Global project.
  • The EMADDC General Dataset, which contains observations from various sources, excluding data from the MET Office Global project.
  • The EMADDC General and MO Global Dataset (this dataset), which combines the General Dataset and the MO Global Dataset, with duplicate observations between these datasets removed. The use of the two individual datasets listed above is discouraged; users are advised to download this dataset instead.

A helper script for file downloads is available on the KNMI open source gitlab repository (https://gitlab.com/KNMI-OSS/emaddc/kdp-notification-client).
