Every station has equal weight. A cohort mean is shown only when every listed station has a valid value with the same method. You can also select an individual station. Groups with different units or measurement profiles are never mixed.
Solid lines: official NRA monthly means, with daily outliers removed by the source. Other segments: monthly means with equal weight per valid day. These methods remain separate. Our monthly rollups require at least 75% of intervals in each valid day and 80% of days per month.
Missing or incompatible months remain gaps, without interpolation. Available history differs by station.
