Southern Hemisphere winds, pressure, and temperature over the 20th century from proxy-data assimilation
This archive contains four reconstructions of annually resolved zonal surface wind (us), sea level pressure (psl), and surface temperature (tas) anomalies in the Southern Hemisphere over the period 1900 to 2005 CE. The anomaly reference period is 1961-1990. The reconstructions are generated using th...
