You will find two CDS catalogue entries for monthly statistics: monthly average, minimum, maximum and standard deviation are available for all initialization dates; additionally . Additionally, for real-time forecast initialization dates there are available 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 available forecasting systems is available both for real-time forecasts (from 2017 onwards) and retrospective forecasts or (referred to as hindcasts) for the period 1993-2016.

There is available one dataset containing One dataset contains surface (or single level) parameters and another one with variables in a set of , the other contains variables on 11 pressure levels spanning from 925 hPa to 10 hPa.
