Extending Greenland Temperature Records into the late 18th Century,

At present, continuous instrumental temperature records for Greenland reach back to
the late 19th century at a few sites. Combining early observational records from
locations along the south and west coasts it has been possible to extend the overall
record back to the year 1784. The new extended Greenland temperature record is 9% incomplete.
There are however sufficient new data (an additional 74 complete winters and 52 complete
summers) to provide a valuable indication of late 18th century and 19th century seasonal trends.
Comparison of the previously published records with additional observational series digitized
from Danish Meteorological Institute Yearbooks, have also revealed inhomogeneities in some
of the existing 20th century temperature records. These problems have been eliminated in
the new extended Greenland temperature record.
A long homogeneous west Greenland instrumental temperature record is of great value for
the interpretation of the growing number of Greenland ice core records.
A first comparison of the new record with highly resolved Greenland ice core data is presented.
Correlations between west Greenland winter temperatures and the ice core winter season proxy
are found to be r=0.67 and r=0.60 for the periods 1785-1872 and 1873-1970 respectively.
