[ncl-talk] Aura MLS data

Hi,

I’m not sure if this is of use, depending on the type of grid you need the MLS O3 data on, but I put together a gridded satellite WV/ozone product called SWOOSH that includes MLS data, among other satellite instruments. You can download the data from 

http://www.esrl.noaa.gov/csd/groups/csd8/swoosh/

Please let me know if you have any questions about this product.

Sean
