Hello,
I am trying to look at the hindcast data for various models. I use this link to download - Seasonal forecast monthly statistics on single levels.
When I select BOM (e.g. for MSLP), it seems there are missing months (January and February). All the other models allow me to select all months for downloading. Is this a bug?
Thank you.
Hi @Zhi-Weng_Chua !
This is not a bug, but an expected (temporary) feature.
After the introduction of a new forecast system into the C3S multi-system production routine tasks it can take a while until all hindcast start dates are (a) produced by the producer, (b) transferred to ECMWF/C3S, (c) processed and published in the CDS. This usually means that there is a lag of typically a few months until all hindcast start dates are available.
The service aim is to have the relevant hindcasts available at least one month before they are needed for the real-time forecasts they relate to, but in any case the place to find all the up-to-date details about what hindcasts are available for each forecast system is the section called ‘Hindcasts’ in the ‘Summary of available data’ page in the Copernicus Knowledge Base documentation.
