The term is a straightforward scientific prefixation meaning one millionth of a bar.

Etymology

Microbar comes from micro meaning 'small', like in microscope, and bar, from a word for 'weight' that is now used to mean 'pressure'. So, a microbar is a very small unit of pressure, equal to one millionth of a bar.
