Raw Dropwindsonde Observations in AVAPS Format

NCAR's Airborne Vertical Atmospheric Profiling System (AVAPS) outputs the data received from a dropsonde in a standardized ASCII format. Each file begins with an identifying code for the sonde, the date and time the sonde was baselined. There follows several lines of headers identifying each column parameter, units, and format. Each line of data will contain the sonde ID, date and time of the meteorological observations, as well as the latitude, longitude, and altitude as determined by the sonde's GPS navigation chip. The usual time interval between observations is one half second.
