[gradsusr] OMI .he5 File

[Jonathan Wynn Smith]

James:

Thanks so much for your response.  Do you know when the Level 3 data will
be ready?  I want to use this data to create a contour plot of mean
tropospheric NO2 column for the month of June 2006.   Do you know of any
user friendly software that I could use to make this plot? IDL is
definitely not the most user friendly. I know I could very easily just use
the DOMINO data but I have been asked to the the OMINO2G product.
