nhtr2005: Northern Hemisphere temperature reconstruction

In GAReg: Genetic Algorithms in Regression

Northern Hemisphere temperature reconstruction

Description

The 2,000-Year Northern Hemisphere Temperature Reconstruction dataset (Moberg et al., 2005) provides annual temperature anomalies for the Northern Hemisphere from AD 1 to 1979, relative to the 1961–1990 mean. The reconstruction combines high-resolution proxy data (e.g., tree rings) with low-resolution proxies (e.g., sediments) using a wavelet-based method to capture variability across multiple time scales.

Usage
