Manual for pilot balloon soundings using a theodolite

Pilot balloon soundings consist on following a buoyant (i.e. rising) balloon using a theodolite. The angle data can be then transformed into wind data assuming a constant ascent rate. This technology, relatively simple and inexpensive can produce important (i.e. large-impact) observations, especially in regions where the current sounding networks are sparse, such as tropical regions. For this reason, we have put together a document that describes the procedure to carry out pilot balloon observations using a meteorological theodolite. Please feel free to access the manual through the following link:
