Reference Radiosonde Data [NCAR/EOL]
https://data.eol.ucar.edu/dataset/77.025

Summary
During the International H20 Project 2002 (IHOP 2002), Reference Radiosondes
were released sixteen times. Either a Vaisala RS80 radiosonde released from
the Homestead site or a National Weather Service (NWS) VIZ radiosonde released
from Dodge City, KS accompanied the Reference Radiosondes during their
flights. Consult the README for dates and times when the Reference Sondes were
released and from which site sondes were released simultaneously. There are
some issues with the Reference Radiosonde data. The following is just a
summary. For a more detailed explanation please see the "Important Notes to
Users" section in the readme file. Pressure Errors: The Reference Sonde (RS)
uses a hypsometer to measure pressure, and this sensor hasbeen found to be
unreliable. We suggest not using the RS pressure data. Time difference: The
time difference in the launch time between the RS sounding files and the
VIZ/Vaisala soundings is due to the RS recording data on the ground, while the
other sondes began recording closer to, or at, the actual launch time. Wind
data: The RS wind data were not corrected for balloon pendulum swing because
the effects of the balloon swing are large, they vary from sounding to
sounding, and because the focus of the RS for IHOP was on the humidity
measurements.
