This tool analyzes which sonde listening stations were able to hear a particular radiosonde during its flight. This is useful for comparing the efficacy of receivers in different locations. It provides statistics including:

• Which listeners heard the sonde
• Frame ranges and coverage percentages for each listener
• First and last altitude and vertical velocity for each listener
• How many listeners heard each transmission point

To see the analysis, enter a sonde serial number and click “Analyze”.
