Doubt about ancillary data sources

[ivgbhavani]

Hi Every one,
Doubt regarding ancillary data to improve the ocean color data quality , I could see many sources for meteorological and gases ancillary data in OCEAN COLOR WEB, mainly NCEP, NCEP-R2, GMAO-MERRA.
Is there any literature about which ancillary data source is the best one, out of the above sources ?
Any Best combinations are there to use them in Met1, met2 and met3 files Ozone1, Oozne2 and Ozone3 options ?
And another question is "Is there any updated met climatology files are avilable instead of met_climatology_v2014.hdf" ?

Suggestions will be helpful.
Thanks in advance

The MERRA-2 products will be replacing NCEP in our processing stream with the upcoming mult-mission ocean color reprocessing.
