This MIL 188-141 2G-ALE session has been copied today 23 Dec. on 09019.0 KHz/USB starting from 1010 UTC. The ALE addresses are: XSS, RAF base in Forest Moor UK belonging to DHFCS-net (Defense High Frequency Communication Service) and UKE304, RAF E3D AWACS Aircraft: respectively TAZ and NATO35 callsigns. The Comms are conveyed by AMD commands which are embedded in 188-141. After the handshake, this is the first message sent by the Awacs, requesting METARs and TAFs (weather informations) for some airports in Cyprus identified by LCRA LCLK, and LCPH:
LCRA - AKROTIRI
LCLK - LARNACA/LARNAX
LCLK - LARNACA/LARNAX
LCPH - PAPHOS/BAF
TAZ
DE NATO35 HELLO WE R RQSTING METARS N TAFS FP LCRA LCLK LCPH TVM
followed by the reply from ground:

TAZ WAIT ONE
something like "wait a moment..." then the requested weather informations for LCRA, LCLK, and LCPH are sent by TAZ (XSS)

METAR (METeorological Air Report) is a format for reporting weather information which is predominantly used by pilots in fulfillment of a part of a pre-flight weather briefing, and by meteorologists, who use aggregated METAR information to assist in weather forecasting. METAR is a common format and highly standardized through the International Civil Aviation Organization (ICAO) which allows it to be understood throughout most of the world.
A typical METAR contains data for the temperature, dew point, wind speed and direction, precipitation, cloud cover and heights, visibility, and barometric pressure. A METAR may also contain information on precipitation amounts, lightning, and other information that would be of interest to pilots or meteorologists such as a pilot report or PIREP, colour states and runway visual range (RVR). TAF (Terminal Aerodrome Forecast) complement and use similar encoding to METAR reports.
TAFs are produced by a human forecaster based on the ground. For this reason there are considerably fewer TAF locations than there are airports for which METARs are available. (quoted from Wikipedia)
