SHMI 18-19 October 2007
If we want to know, if we change the climate, then we must know, to which extend it changes by itself. That it one of the reasons for the great value of the old climate data.
The foundation of The Danish Meteorological Institute in 1872 marked the beginning of the official instrumental meteorological series i Greenland.
From 1873-1983 yearbooks have been produced with varying contents and size.
From app. 1958 digitised observations exist in the climate databases at DMI.

From 1784 a composite SW Greenland temperature series is processed….not least because of H.H. Lamb.
Composed of series from Qaqortoq, Nuuk and Ilulissat.

Continuously updated series of annually temperatures from 1873 from seven localitions.
The series have been quality checked the best way possible including the processing of NACD - North Atlantic Climatological Dataset 1890-1990.
