| description | <p>Continuous very long baseline interferometry (VLBI) observations are designed
to obtain highly accurate data for detailed studies of high-frequency Earth
rotation variations, reference frame stability, and daily to sub-daily site
motions. During the CONT-17 campaign that covered a time span of 15 days
between 28 November and 12 December 2017, a comprehensive data set of
atmospheric observations was acquired at the Geodetic Observatory Wettzell,
where three radio telescopes contributed to three different networks which
have been established for this campaign. These data were supplemented by
weather model data. The data set is made available to all interested users in
order to provide an optimal database for the analysis and interpretation of
the CONT-17 VLBI data. In addition, it is an outstanding data set for the
validation and comparison of tropospheric parameters resulting from different
space techniques with regard to the establishment of a common atmosphere at
co-location sites.</p>
<p>The regularly recorded atmospheric parameters comprise many meteorological
quantities (pressure, temperature, humidity, wind, radiation, and precipitation)
taken from the local weather station close to the surface, solar radiation
intensity, temperatures up to 1000 m above the surface from a temperature
profiler, total vapor and liquid water content from a water vapor
radiometer, and cloud coverage and cloud temperatures from a nubiscope.
Additionally, vertical profiles of pressure, temperature, and humidity from
radiosonde balloons and from numerical weather models were used for
comparison and validation.</p>
<p>The graphical representation and comparison show a good correlation in
general but also some disagreements in certain weather situations. While the
accuracy and the temporal and spatial resolution of the individual data sets are
very different, the data as a whole characterize the
atmospheric conditions around Wettzell during the CONT-17 campaign comprehensively and
represent a sound basis for further investigations
