Aircraft-based Observations Data GTS Access

Aircraft-based observational data can be accessed from the WMO Global Telecommunications System.

The general requirements for transmission of data on the GTS are described in the WMO Manual on Codes, WMO-No. 306.

AMDAR Data

AMDAR data is currently transmitted in both text (FM42, see Manual on Codes, Volume I.1 Alphanumeric Codes) and binary (BUFR) (FM94, see Manual on Codes, Volume I.2 Binary Codes) formats.

Aircraft-based Observation Data Online Access

The USA National Oceanic and Atmospheric Administration (NOAA), Earth System Research Laboratory (ESRL), Global Systems Division hosts an online site for display and monitoring of aircraft-based observations data on the GTS.

The ESRL/GSD AMDAR Data Display is provided via two alternative applications, one relying on the Java platform and the other not requiring Java.

A demonstration version (data less that 48 hours old are not shown) of the AMDAR Data Display java application is available here.

The operational GSD AMDAR Data Display site and applications are available to WMO Members that require its use for aircraft-based observations and AMDAR data display and monitoring, upon request and approval by GSD. Contact the Secretariat for more information.

More information on the ESRL/GSD AMDAR Data Display and the USA AMDAR/MDCRS Programmes is available from the NOAA/ESRL/GSD Aircraft Data Web.
