Explanation for the "NRT" designator in the standard file naming convention

Could someone explain the "NRT" designator in the file naming convention, in more depth than the description "Near Real Time"?

For example, on Nov 1, 2022, there is an NRT version and a non-NRT version available:
AQUA_MODIS.20221101.L3m.DAY.IOP.bb_531.4km.nc 2023-01-31
AQUA_MODIS.20221101.L3m.DAY.IOP.bb_531.4km.NRT.nc 2022-11-03

The general trend seems to be that the NRT is made available within a day or so of the measurement date, with the non-NRT made available within ~2 months of the measurement date.

What new information is applied to the non-NRT version that was not available for the NRT version?
