| ## Level 2 Combined Sounding Products | ||
| The IASI level 2 products contains derived atmospheric profiles of temperature, water vapour, ozone and trace gasses. The availability of these profiles depend on cloud cover and therefore the number of profiles will vary through out the product. These variables of changing size is padded with a fill values (default to `missing`) to generate an array that fits with the `MetopDataset` interface. This example plots the temperature and water vapour profiles next to a map showing the location of the observation. The example uses `maskingvalue = NaN` for selected variables to avoid `missing` values. | ||

One suggestion, you could add a paragraph explaining why the fg_ profiles are the preferred.

Edits in the L2 plotting example for IASI: Emphasis is put on reading the profiles from the statistical retrieval and filtering them by quality indicator value. Also added log axes for the profile plots
