PCPN stands for "Precipitation Amount (6-hour)" in the remarks section of a METAR report. Reports the total precipitation accumulation over the preceding 6-hour period, encoded as a five-character group starting with 6 followed by four digits in hundredths of an inch. For example, 60042 means 0.42 inches of precipitation accumulated in the last 6 hours. Useful for assessing the overall precipitation trend.
PCPN appears in the remarks (RMK) section at the end of a METAR observation. The remarks section follows the main body of the METAR and provides additional details about the observation that don't fit into the standard coded format.
Here is an example: "60042". This appears in the remarks section and indicates precipitation amount (6-hour) information as part of the weather observation.
