Hence, they have a different dimension size...

Question: What is the data Latency of MERRA/MERRA-2?

Re: GES DISC FAQ - What is the data Latency of MERRA/MERRA-2?

It can depend on the level of work and holiday occurrences that the operations group contends with, but typically its posted 2-3 weeks after the end of the month, though can be sooner. Majority of the time the data becomes available between the 20-23 of the following month.
