Description: | The first pressure value reported by the radiosonde (t = 2 sec) is 968.0. The surface
pressure value was 974.5 hPa. This difference is greater than the expected (normal) change
and may mean that either the pressure sensor was jarred during launch or the system
mis-identified the actual launch start time. Further clarification requires analysis of the
raw data which will take some time. The altitude values for this sounding may be
incorrect. The ascent rate values during the first 30 seconds also will be wrong. Because the
system will reject samples with out of bound ascent rates (i.e., during the first 30
seconds), the temperature and RH values also will be incorrect (a result of interpolation).
Relative height values after 30 seconds should be okay. |
