1. Context.The concept of "nominal" start date in lagged start ensembles

...

Due to a number of reasons, members from ensembles using the "lagged start" approach are bundled together at C3S and labelled with a "nominal" start date (see details here).

The C3S seasonal forecast datasets are based on GRIB files stored at ECMWF MARS archive where that "nominal" start date is used to index the monthly data (monthly statistics and monthly post-processed products like anomalies). Hence, the details about the original initialization date could get lost in those files. Nonetheless, the data at daily and sub-daily time frequencies is always encoded with the real initialization date, as it can be seen in the example below:

...

In the future, systems using the lagged start approach introduced into C3S will also use localDefinitionNumber=12

What has changed?

localDefinitionNumber=16
(before December 2019)

localDefinitionNumber=12
(after December 2019)
Date used in the CDS requestsNominal start date
GRIB keywords: dataDate, dataTime
Nominal start date
GRIB keywords: indexingDate, indexingTime
Real start dateNot availableGRIB keywords: dataDatedataTime


It is important to bear in mind that most common grib tools will read dataDate and dataTime
