Example Data of Continuous Observations and Ensemble Forecasts

Description

Continuous observations (obsv) and 9-member ensemble forecasts (fcst) of the Nino-3.4 index for January 1961-2000. The forecast data stem from model runs initialized using data for the preceding August 1960-1999.

Details

The forecast data are from the coupled ocean-atmosphere model of the Centre National de Recherches Meteorologiques (CNRM) of Meteo France and were generated as part of the "Development of a European Multimodel Ensemble System for Seasonal to Interannual Prediction (DEMETER)" project (Palmer et al. 2004). Note that also the examples presented in the 2AFC paper by Mason and Weigel (2009) are based on these data.
