Re: which plot type I could use from Ziying Li

Hi Dennis,

You can get the file through:
<ftp://ftp.hdfgroup.uiuc.edu/pub/outgoing/eseo2/aura_samples/swath/OMI-Aura_L2-OMNO2_2008m0720t2016-o21357_v003-2008m0721t101450.he5>
TES-Aura_L2-O3-Nadir_r0000011015_F05_07.he5<ftp://ftp.hdfgroup.uiuc.edu/pub/outgoing/eseo2/aura_samples/swath/TES-Aura_L2-O3-Nadir_r0000011015_F05_07.he5>

Below is the information I extract. Dataset I chose is O3 and 2 dimension
fields are pressure and time.
