Stations are subject to mechanical and climatological variables, so there can be significant variations in the accuracy of the data collected when equipment is adversely affected by extreme weather and/or technical problems.

Barometric pressure is corrected for elevation. The rain bucket is emptied every day at 4PM. Data is updated every 20 seconds, and averaged and recorded every five minutes.
