Upon returning to the RRS workstation, there will be a flashing message saying that a balloon release was detected. Click “Continue.” A window will appear with the surface observations before launch and the conditions at launch. Adjust the cloud cover code in the Launch section, if needed. The RWS software allows the surface observations to be changed at any time during a flight. It is important to note that if surface observations are changed any edits to the incoming data will have to be performed again. Click “OK.”
The Received PTU Tabular Display window will appear. This window shows the raw data incoming from the sonde. Scroll down until and find the release point. The release point will be at time = 0.00 minutes and marked with a red line. Check that the release data is similar to the RSOIS observation.
There are some circumstances that require a change in the release point. Suppose the sonde dipped towards the ground briefly. Check the Processed Tabular Display. The pressure should be falling and geopotential height should be rising. If this is not the case, you could have a bad sonde, or it might just be a faulty data point at release. To change the release time, find the new start time. Click on Tools -> Change Release Point. Enter the new release time and continue. Any quality control edits will have to be performed again. A superadiabatic lapse rate is also a reason to modify the release point.
To view the status of the incoming data, it is recommended that several plots are opened to watch. Some of these include RH, Temperature-RH, Trajectory, and Wind. Open these by selecting them under “Plots.” Go to “Tables” and select Received PTU and Processed. In “View” select TRS Display. To make all of the opened windows visible, go to “Window” -> “Tile.”
Once the observer has a display that is suitable, it is recommended that the display be saved as a workspace for the next time a flight is worked. Go to “Flight” -> “Save As Workspace.” Enter the observer’s name or initials and click “Save.”
To open a saved workspace, go to “Flight” -> “Open Workspace.”
