Arctic temperatures

Averaged temperatures

NOAA GHCND stations included

Method

The following steps were used to produce a single plot of temperatures from the multiple stations.

  1. Extract all the stations with more than 50 years of records of maximum and minimum daily temperature
  2. Group the data by station
  3. Subtract the overall monthly means for each station from the observed daily values.
  4. Take the mean of all these anomalies for each day, and then average over all the records for the stations included.
  5. Add back the mean value for all the stations in the area for that day.
  6. Plot the time series as a dynamic graph with rolling average. Note this value can be changed by the user.
