Common remarks — learn these first
AO2Automated station WITH a precipitation discriminator — it can tell rain from snow.
Why it matters: Tells you the observation came from automated sensors, so a human may not be checking it.
AO1Automated station WITHOUT a precipitation discriminator — it can't tell rain from snow.
Why it matters: Precipitation type may be missing or wrong. Use extra caution in winter.
SLP132Sea-level pressure 1013.2 hectopascals (millibars). Put a 9 or 10 in front of 132, then add a decimal.
Why it matters: Forecasters compare sea-level pressure between stations to find highs, lows, and fronts.
SLP982Sea-level pressure 998.2 hectopascals (millibars). Put a 9 or 10 in front of 982, then add a decimal.
Why it matters: Forecasters compare sea-level pressure between stations to find highs, lows, and fronts.
P00030.03 inches of precipitation fell in the last hour.
Why it matters: Recent precipitation means wet runways, lower visibility, and possibly more on the way.
P0000A trace of precipitation fell in the last hour (too little to measure).
Why it matters: Recent precipitation means wet runways, lower visibility, and possibly more on the way.
T01390083Exact temperature 13.9°C, exact dew point 8.3°C. A leading 1 means minus; a leading 0 means plus.
Why it matters: The main body rounds to whole degrees. This gives tenths — handy when the spread is small.
T10501072Exact temperature -5.0°C, exact dew point -7.2°C. A leading 1 means minus; a leading 0 means plus.
Why it matters: The main body rounds to whole degrees. This gives tenths — handy when the spread is small.
$The station needs maintenance.
Why it matters: The data may still be fine, but treat the report with a little extra skepticism.
Advanced remarks
Locked — complete Level 9 (the full base METAR) to unlock peak wind, wind shifts, lightning, precipitation begin/end times, and more.
Remarks you can see
Some remarks describe something in the sky. Pick one and look for it from the end of the runway.
Rain falling from a cloud but drying up before it reaches the ground.
DSNT means distant — more than 10 statute miles away. VC (vicinity) is 5 to 10 miles. The letters after it are the compass direction from the airport.
