If you are interested in atmospheric soundings, you might want to check out the Storm Prediction Center (SPC) Sounding Analysis Archive. This web page provides access to current and recent observed radiosonde data in skew-t format, as well as a sounding climatology for various locations in the United States. You can also find some experimental forecast tools and parameters based on the sounding data.

What is a sounding? A sounding is a measurement of the vertical profile of temperature, humidity, pressure, wind speed and direction in the atmosphere. It is usually obtained by launching a balloon with a radiosonde attached, which transmits the data back to a ground station. Soundings are useful for studying the stability, moisture, and wind shear of the atmosphere, which are important factors for severe weather forecasting.

The SPC Sounding Analysis Archive allows you to view the skew-t diagrams of the soundings for any available site and time. A skew-t diagram is a graphical representation of the temperature and dew point as a function of pressure or height, with the temperature axis skewed to the right. The diagram also shows the wind speed and direction as wind barbs along the right side. You can use the skew-t diagram to calculate various thermodynamic and kinematic parameters, such as CAPE, CIN, LCL, LFC, EL, SRH, and more.

The web page also offers a sounding climatology option, which shows the distribution of different parameters over a selected time range for a given site. You can compare the current or recent observed values with the historical values to see how anomalous they are. You can also filter the data by certain criteria, such as CAPE or PW, to see how they affect other parameters.

The SPC Sounding Analysis Archive is a valuable resource for meteorologists, researchers, students, and weather enthusiasts who want to learn more about the vertical structure of the atmosphere and its implications for severe weather. You can access it at https://www.spc.noaa.gov/exper/soundings/.
