Nevertheless, the large dip during 2016 in both difference series is clearly down to rapid Arctic warming, as the following chart showing temperature
anomaly by latitude makes very clear.

But if you can you will be able to locate
the anomalies by latitude and longitude, but then I forgot, you do not know and are incapable of finding out the coordinates for Barrow.

At the global scale, outgoing LW flux
anomalies are partially compensated for
by decreases in mid
latitude cloud fraction and cloud height, as observed
by Moderate Resolution Imaging Spectrometer and Multi-angle Imaging Spectro Radiometer, respectively.
Raw land temperatures were calculated
by assigning each station to a 5 × 5
latitude / longitude grid box, converting station temperatures into
anomalies relative to a 1971 - 2000 baseline period, averaging all the
anomalies within each grid box for each month, and averaging all grid boxes for each month weighted
by the land area within each grid box.
The disruption part is because they realized that greenhouse warming wasn't evenly distributed across the globe but rather is apportioned
by latitude with higher latitudes getting a lot and lower latitudes getting little with the Arctic glowing like a hot coal in temperature
anomaly maps.
By convention, the high index polarity of the annular modes is defined as lower than normal pressures over the polar regions and westerly wind
anomalies along ~ 55 - 60 degrees
latitude.»
SST
anomalies (from a 1961 to 1990 average) are first averaged into 1 °
latitude by 1 ° longitude boxes for five - day periods; the
anomaly for a given observation is calculated from a 1 ° box climatology that changes each day throughout the year.
That is, if a 5 - deg
latitude by 5 - deg longitude grid does not have a temperature
anomaly value in a given month, it is not included in the global average value of HADCRUT4.
BTW, NYC and Des Moines are almost on the same
latitude and only about 1000 km apart, so
by Hansen's rule you don't need the Des Moines data as it is less than 1200 km from NYC with its more convenient
anomalies.
