What does P0000 mean in METAR data?

Explanation:
In METAR data, the P prefix is used to show how much precipitation has fallen, in inches, during the past hour. The four digits that follow represent that amount to the nearest hundredth of an inch. So P0000 means there has been no measurable precipitation in the last hour. This is about precipitation, not pressure, temperature, or a pressure trend, which is why that option doesn’t fit. For example, P0035 would indicate 0.35 inches of rain in the past hour.
