MISR Level 2 Surface parameters V003
MISR Level 2 Surface parameters V002
It's not clear from the product pages, everything listed appears to be the same.
There is a format difference, and a temporal coverage difference, but these are not what are usually considered 'versions'. Version implies an algorithm and product difference and would require separate pages, while a format difference would not.
In any case, it should be clear to the user what is meant by the different versions.
The link on the product page to the 'ASDC Overview of MISR File Naming and Versioning Conventions' page was not helpful.
Having two particular versions available may be confusing and are sometimes done at the request of the Science Teams to support ongoing research and publications. In short, both the aerosol and land surface product format is changed from HDF-EOS2/HDF4 in V002 to NetCDF4/HDF5 in V003.
Please see the original announcement:

Data Product Specification (DPS) for Land Surface Product:

That is my question.
I am already aware of the format differences.
A user understands format differences more clearly than version differences.
For instance, these products are the same version, different formats.
This distinction seems to be handled differently for L2 products.
It's rather confusing.

We'll add any additional information received on this post.
We've received the following response from the MISR Science Team:
Best RegardsApart from the formatting changes, the new L2 Land Product uses the new version of the L2 Aerosol Product as input. Since the new aerosol product release incorporates very significant algorithm changes, it was appropriate to designate a new version of the land product as well. There were also a few minor changes made to the L2 Land Product algorithm at the same time.
