What is the purpose of METAR and how often is it updated?

METARs are aviation weather reports that provide the latest surface weather observations for airports and weather stations. They are not forecasting tools, nor do they summarize climate normals. The purpose is to give pilots and aviation professionals real-time information about current conditions to support safe takeoffs and landings and flight planning. A METAR reports elements such as wind direction and speed, visibility, present weather (like rain or snow), sky condition and cloud amount, temperature and dew point, and the altimeter setting. These observations are typically issued on an hourly schedule, though special METARs (SPECI) can be released between the routine hours if significant weather changes occur. So, the best description is that METARs report current surface weather observations and are typically updated hourly.
