ERA5 dataset is three years outdated?

Hi,

I am trying to access ERA5 dataset from Planetary Computer Data Catalog using Python.

https://planetarycomputer.microsoft.com/dataset/era5-pds

On the page, it says that the temporal extent for this dataset is 01/01/1979 – Present, but if I follow the tutorial on the Example Notebook and change the code to

search = catalog.search(
    collections=["era5-pds"], datetime="2021-01", query={"era5:kind": {"eq": "an"}}
)

for example, the search returns no items.

In fact, in https://planetarycomputer.microsoft.com/api/stac/v1/collections/era5-pds/items it is clear that the "end_datetime":"2020-12-31T23:00:00Z".

Is this correct?
I am very frustrated with that because the service worked very well for my research, but I need data up to the present.

Thanks for the service, it accesses the data faster than I was expecting.

Best,

Inizia dalla pagina del dataset ERA5, dal relativo Example Notebook e dall’endpoint degli elementi della collection STAC citato nel report. Confronta l’estensione temporale visualizzata con l’end_datetime dell’API e la ricerca Python per il 2021; l’issue è completata quando i metadati del catalogo e gli elementi restituiti riflettono accuratamente l’intervallo temporale disponibile del dataset.
