MLS/Aura L2 O3 Mixing Ratio V005 (ML2O3) versions.

[sdipede]

Dear EARTHDATA forum,

I am downloading a large dataset of "MLS-Aura_L2GP-O3_v05-*.he5" from 2018 till 2025, and I realized that the versions are different across the years. I encounter: v05-00, v05-01, v05-02, v05-03, depending on the day. But in the documentation: https://acdisc.gesdisc.eosdis.nasa.gov/data/Aura_MLS_Level2/ML2O3.005/doc/, I only see information about the difference between v05-00 and v05-01.

- I would like to ask if only the data on the website are available, and if for example version v05-01 of this dataset MLS-Aura_L2GP-O3_v05-00-c01_2019d019.he5 is also available

- Do you have any information about the impact of using different version of ML2O3?

Thank you in advance for reading my message and your answer.

Kind regards,
Serena Di Pede

On the MLS website (https://mls.jpl.nasa.gov/) there is a documentation page with a table that explains the differences in the minor version releases (at https://mls.jpl.nasa.gov/eos-aura-mls/documentation.php):

v05.01 Minor bug fix related to flagging of bad GPH values
v05.02 Fixed minor bug in Level 1's calibration of the MLS instrument's digital auto-correlators (DACS)
