A daily Azores–Iceland North Atlantic Oscillation index back to 1850
We present the construction of a continuous, daily (09:00 UTC), station-based (Azores–Iceland) North Atlantic Oscillation (NAO) Index back to 1871 which is extended back to 1850 with additional daily mean data. The constructed index more than doubles the length of previously existing, widely availab...

We present the construction of a continuous, daily (09:00 UTC), station-based (Azores–Iceland) North Atlantic Oscillation (NAO) Index back to 1871 which is extended back to 1850 with additional daily mean data.
