Regarding bins in MERRA

[dinesh_5497]

What does bin means in MERRA data?

[GES DISC - jimacker]

Regarding your question, can you provide a MERRA-2 document or web page where the term "bin" is used? Bin commonly refers to a data storage location in which all valid observations for a particular spatial resolution are kept, until averaging over a time period is performed to provide a value for a gridded data product. So it would be helpful to know the context in which the term "bin" occurs. We can consult with our MERRA-2 data experts once we have such information from you.
