METAR is the international standard code format used to publish reports of meteorological observations at airports performed periodically, which is analogous to the HS code used in the U.S.. Is an acronym translated from French (Metéorologique Aviation Régulière) as routine aeronautical meteorological report (in English: Meteorological Aerodrome Report). SPECI code is the code name given to METAR issued at a special unscheduled routine, caused by changes in weather conditions. SPECI acronym translates as Special Selection for Weather Report Aviation.
is used by meteorologists and airmen to aid in weather forecasting, and primarily by pilots of aircraft to meet the airport's weather station and act accordingly. METAR reports usually come from the airports. Typically are issued every half hour or an hour. This report is achieved for a given airport by ICAO code / ICAO (examples: KMIA Miami, USA and MGGT Airport La Aurora, Guatemala) and includes among other data: wind, visibility, cloud cover and temperature.
This post will learn to read a METAR report real.
