Daily data
You will find two CDS catalogue entries labelled 'daily data'; these contain data at daily or subdaily frequency (6h or 12h) . The output of the different forecasting systems is available both for real-time forecasts (from 2017 onwards) and retrospective forecasts (referred to as hindcasts) for the period 1993-2016.
One dataset contains surface (or single level) parameters, the other contains variables on 11 pressure levels spanning 925 hPa to 10 hPa.
Monthly data
You will find two CDS catalogue entries for monthly statistics: monthly average, minimum, maximum and standard deviation are available for all initialization dates. Additionally, for real-time forecast initialization dates you will find the ingredients to calculate the forecast monthly anomalies: the forecast ensemble mean and the hindcast climate mean. The output of the different forecasting systems is available both for real-time forecasts (from 2017 onwards) and retrospective forecasts (referred to as hindcasts) for the period 1993-2016.
One dataset contains surface (or single level) parameters, the other contains variables on 11 pressure levels spanning 925 hPa to 10 hPa.
Post-processed data
You will find two CDS catalogue entries for real-time forecast monthly anomalies; each contains the anomalies for the ensemble mean for each system and the individual ensemble members.
Anomalies are just available for real-time forecasts start dates (from 2017 onwards).
One dataset contains surface (or single level) parameters, the other contains variables on 11 pressure levels spanning 925 hPa to 10 hPa.
