Abstract

Climate eld reconstructions from networks of tree-ring proxy data can be used
to characterize regional-scale climate changes, reveal spatial anomaly patterns
associated with atmospheric circulation changes, radiative forcing, and largescale
modes of ocean-atmosphere variability, and provide spatiotemporal targets
for climate model comparison and evaluation. Here we use a multiproxy network of tree-ring chronologies to reconstruct spatially resolved warm season
(May-August) mean temperatures across the extratropical Northern Hemisphere
(40-90oN) using Point-by-Point Regression (PPR). The resulting annual maps
of temperature anomalies (750 to 1988 CE) reveal a consistent imprint of volcanism, with 96% of reconstructed grid points experiencing colder conditions
following eruptions. Solar inuences are detected at the bicentennial (de Vries)
frequency, although at other time scales the inuence of insolation variability
is weak. Approximately 90% of reconstructed grid points show warmer temperatures during the Medieval Climate Anomaly when compared to the Little
Ice Age, although the magnitude varies spatially across the hemisphere. Estimates
of eld reconstruction skill through time and over space can guide future
temporal extension and spatial expansion of the proxy network.
