NUCAPS Comparison to Radiosonde sounding

We had a 14Z IASI satellite pass this morning. Here is a comparison of a NUCAPS sounding for a point near Nashville to the 12Z Nashville radiosonde launch.

The NUCAPS sounding is definitely smoothed compared to the radiosonde sounding, and the airmass is not well-resolved near the surface on the NUCAPS.
However, the NUCAPS sounding does hint at the nearly saturated layer from around 850mb-750mb. The overall instability is fairly similar in both soundings.
