Sondehub also has a separate utility for tracking meteorological radiosondes (weather balloons), . Using the browser on my phone and a tape measure antenna with my HT, I've recovered 3 sondes. It's a fun way to practice radio direction finding between fox hunts. I even set up a simple station at my house for tracking and uploading sonde telemetry to sondehub.
