Display a Skew-T using GOES-16 Infrared + RAP13/NAM12/GFS20 Data

Contributed by Jared Smith (@jaredwsmith)

Getting a floating Skew-T in AWIPS is a breeze:

1. Load any infrared satellite product into a map view. For this one, I’m using GOES-16 Channel 13 (Clean IR Window), but any infrared channel will do.

2. Right-click and hold on the map to get the context menu. From the menu, select RAP-13km from the Sample Cloud Heights/Radar Skew T menu.

3. Right-click and hold on the map again and select Sample. The cursor will then display cloud height in addition to cloud top temperature.

4. To display the floating Skew-T, go back to the Sample Cloud Heights/Radar Skew T menu in the context menu and select “Skew-T.”

5. Once you do this, you’ll see the Skew-T window pop up! It displays temperature and dewpoint profiles as depicted on the current run of the RAP13 valid for that time. The estimated cloud top height for the cloud under the cursor (based on the model data) is also plotted on the chart as a yellow dot.
