The tree-ring width and the maximum wood density of Norway spruce (Picea abies (L.) Karst.) have been examined in order to reconstruct air temperature of the summer half-year during the period 1804 - 1989. The trees examined come from a natural spruce stand of Labský důl (Elbe Valley) in Krkonoše (Giant Mts.), North Bohemia. The results obtained by this way have been compared with a similar reconstruction made for Central Europe and with air temperature records from the Prague-Klementinum station. Both temperature series (reconstructed and measured), however, show only 36 % of commonly clarified variability. Differences may follow from the standardization of dendrochronologies as well as from other factors which may have influenced the growth of spruce. The quality of air temperature measurement may play also role.
