Description: | These five soundings, done in succession on 11/07/2002 as part of the SCM/IOP are
contaminated by interference. I can't tell whether the problem has to do with improper tuning of
the radiosondes, inadequate frequency separation among radiosondes launched from
different locations, or some other operator problem. I suspect that there is an operator
component to the difficulty because the surface pressure is given as an unreasonably low 896.6
hPa on the 1730 sounding and 886.1 hPa on the 2331 sounding. This may indicate that the
ground station was locked another station's radiosonde rather than on the B4 radiosonde. |
