We have just started the Timely Update service for the Copernicus Artic Regional Reanalysis (CARRA) datasets. In practise it means that every end of the month (on the 27th at 3 pm UK time) we are going to update the 4 CARRA datasets adding an additional month to the catalogue entry. The time lag with respect to the real time will be 2-3 months, which means that at the end of February we publish the datasets until the end of December 2022 (in March we will add January 2023 and so on).
