These photographic prints, arranged in chronological order, depict radiosondes (and the occasional pilot balloon) and related preparation, launch, tracking, and data-collection activities. Some of these prints are from newspaper archives, some I bought on eBay (often without any provenance), and some were printed from negatives I purchased.
The photos are displayed in chronological order.  Click any photo to see a larger image.
