What format are hourly weather observation reports provided in?

Hourly weather observation reports are provided in the METAR format. METAR stands for Meteorological Aerodrome Report, and it is a standardized format used to report weather conditions at airports and aerodromes. These reports include information such as temperature, dew point, wind speed and direction, visibility, weather phenomena, and more. They are typically issued once an hour, but can be updated more frequently when significant changes in weather occur.

TAF, on the other hand, refers to Terminal Aerodrome Forecast and is used for forecasting weather conditions rather than reporting them. SPECI is a special weather report issued when there are significant changes in conditions between regular METAR reports, while AWOS stands for Automated Weather Observing System, which is a system that collects and disseminates weather data but does not represent a format for weather observation reports.
