METAR
Acronym for METeorological Aerodrome Report. It is the primary observation code used in the United States to satisfy requirements for reporting surface meteorological data.
METAR
METeorological Aviation Report. An evaluation of selected weather elements from a site on or near the ground according to a set of procedures.

METAR This is an acronym for the meteorological aviation reports which specifically refer to the international coded reports issued hourly from airport stations.
The METAR generating the pictured Weatherpixie is EGLL 270750Z 23006KT 200V260 9999 FEW025 BKN070 16/12 Q1017 NOSIG.
SPECI - In the METAR observation program, a surface observation issued on a nonroutine basis as dictated by changing meteorological conditions.
It is reported as "SA" in an observation and on the METAR. SANDSTORM A strong wind carrying sand particles through the air. They are low level occurances, usually only ten feet in height to not more than fifty feet above the surface.
TAFs use the same weather code found in METAR weather reports.Terrain Forced FlowAn airflow that is modified or channeled as it passes over or around mountains or through gaps in a mountain barrier.
METAR:.........Routine scheduled weather observations.
NE:..................On a Radar Chart: No Echoes:
PIBAL:............Pilot Balloon.
Pirep:..............Pilot Report.
RADAT:..........Freezing Level.
Prevailing Visibility:.........
It is reported as "R" in an observation and on the METAR. The intensity of rain is based on rate of fall. "Very light" (R--) means that the scattered drops do not completely wet a surface. "Light" (R-) means it is greater than a trace and up to 0.
Hail is considered to have a diameter of 5 millimeter or more; smaller bits of ice are classified as ice pellets, snow pellets, or graupel. Individual lumps are called hailstones. It is reported as "GR" in an observation and on the METAR.
It is classed as a lithometeor and is encoded BLDU as an obstruction to vision in an aviation weather observation (METAR).
