Example Data of Dichotomous Observations and Dichotomous Forecasts
Description
Dichotomous observations (obsv) and dichotomous 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. Definition of an
"event" in the observations respectively forecasts: obsv/fcst >= 27 C.
Format
A data frame with 40 rows and 3 columns:
- years
integer, year of observation (1961-2000)
- obsv
integer, dichotomous observations
(0/1; event defined as Nino-3.4 index >= 27 C)
- fcst
integer, dichotomous forecasts
(0/1; event defined as Nino-3.4 index >= 27 C)
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.
