Torneträsk tree-ring width (TRW) and density (MXD) AD 500-2004
Tree-ring width (TRW) and maximum density (MXD) from Tornetrask in northern Sweden, covering the period AD 500 - 2004. Non-climatological growth trends in the data are removed using Regional Curve Standardization (RCS). A climate reconstruction based on MXD captures 63-64% of the inter-annual summer temperature variation. Variables: MXDrcs = Maximum ring density, with regional curve standardization MXDlow = Low frequency (c. 100 yrs) variation,with 95% confidence interval TRWrcs = Tree-ring width, with regional curve standardization TRWlow = Low frequency (c. 100 yrs) variation,with 95% confidence interval

Processes and phenomena of the atmosphere.
Pertaining to the measurement and analysis of ancient tree rings todetermine environmental conditions during that tree's lifetime andextrapolate that to climatic conditions. The study of tree rings related topast climate conditions is called dendroclimatology. Variations in tree ringwidths from year to year are recognized as an important source of chronologicaland climatic information. The width of a tree ring is a function of manyvariables including tree species, age, availability of stored food within thetree, soil nutrients, and climatic factors such as precipitation, sunshinetemperature, winds and humidity.
Reconstruction of past climatic conditions using paleoclimate proxy records\n(tree rings, ice cores, etc.)
The study of paleoclimates throughout geologic time, and of the causes of their variations, on either a local or a worldwide basis. It involves the interpretation of glacial deposits, fossils and sedimentologic and other types of data.
Physical conditions in the atmosphere. Includes spatial data based on measurements, on models or on a combination thereof and includes measurement locations.
