Finding Radiosondes (RDF) to LMG6 Ground Tracking and
LMS6 Radiosondes On or about September 20, 2013
On or about September 20, 2013, the Kodiak UA site will

the transition, UA observations may be out for up to 3 days.
NAME WMO# SID LMS START DATE
KODIAK 70350 PADQ September 18-25 2013
When implementation is complete, the Kodiak site will gather
meteorological data from the newest category of Global
Positioning System (GPS) radiosondes the LMS6. The assigned
equipment code is: 48208. The leading 4 indicates a correction
is applied for solar and infrared exposure. The 08 suffix
indicates automatic satellite navigation. This code appears
immediately after the heading, 31313, in the TAA, TTB, TTC and
TTDD messages.
The format of the messages will be the same WMO format for coded
UA messages used with the MicroArt legacy system. The number of
levels in the TTAA, TTBB, TTCC, TTDD, PPBB and PPDD parts will
be relatively unchanged.

parts of the message will be included with each part of the
thermodynamic message parts.
