Sounding Viewer Version 1.4.1

New Features in v1.4.1:

• Fixed a constant in ECAPE calculations to more accurately set the entrainment rate.

New Features in v1.4.0:

• Irreversible Adiabatic and Entraining Ascent are now plotted, and convective parameters can be computed using these parcels instead of the traditional Pseudoadiabatic Non-Entraining parcel. Irreversible Adiabatic Ascent is used by default. Irrev. Adiab. ascent and Pseudoadiabatic ascent can be toggled by pressing I while viewing a sounding, and whether the Entraining or Non-Entraining parcel is focused can be toggled by pressing E.

This sounding viewer contains integration with both the IGRA2 database and the SPC Experimental Soundings page as well as an API to use the program as part of your own project.

For non-programmers, this program includes a graphical interface that will help you easily view any sounding chart from any station on any date, as long as it is in NOAA's archive.

Sounding Viewer Version 1.3

New Features:

• Current soundings outside of the US now use GFS data. This is to address how IGRA2 runs a couple days behind. Work is ongoing to find more up-to-date sources and to add more models to choose from.

This sounding viewer contains integration with both the IGRA2 database and the SPC Experimental Soundings page as well as an API to use the program as part of your own project.

For non-programmers, this program includes a graphical interface that will help you easily view any sounding chart from any station on any date, as long as it is in NOAA's archive.

Sounding Viewer Version 1.2

New Features:

• Frost point trace as a bluish-green dashed line, optional and turned off by default. Press F to turn on.

This sounding viewer contains integration with both the IGRA2 database and the SPC Experimental Soundings page as well as an API to use the program as part of your own project.

For non-programmers, this program includes a graphical interface that will help you easily view any sounding chart from any station on any date, as long as it is in NOAA's archive.

Currently, soundings from outside the United States are not well tested. Please submit a bug report if you encounter any issues.

Sounding Viewer Version 1.1

New Features:

• Inferred Temperature Advection plot, located between the Skew-T and the Hodograph.

This sounding viewer contains integration with both the IGRA2 database and the SPC Experimental Soundings page as well as an API to use the program as part of your own project.

Sounding Viewer Version 1.0

This sounding viewer contains integration with both the IGRA2 database and the SPC Experimental Soundings page as well as an API to use the program as part of your own project.

For non-programmers, this program includes a graphical interface that will help you easily viewer any sounding chart you want.

Currently, soundings from outside the United States are partially broken. I plan to fix that later, but I wanted to release this version that does work for the US now.
