What type of weather report provides real-time information about current conditions?

The type of weather report that provides real-time information about current conditions is the METAR. METAR reports are standardized aviation routine weather reports that include essential meteorological information such as temperature, wind direction and speed, visibility, cloud cover, and any significant weather events. They are typically issued at least once an hour and are critical for pilots and aviation personnel to understand the current weather conditions at airports and flight paths. This up-to-date information is essential for ensuring safety and efficient flight operations.

In contrast, TAF (Terminal Aerodrome Forecast) reports offer forecasts for specific terminals over a period, SIGMETs (Significant Meteorological Information) provide warnings about severe weather that could affect safety, and AIRMETs (Airmen's Meteorological Information) are intended for pilots of smaller aircraft to highlight weather that could cause hazards, but they do not deliver real-time conditions like METARs do.
