Platform/Measurement: sgpsondewrpnB4/all
What level data: (raw,a0,a1,b1,c1 etc):
What location was the data collected at: B4 (Vici)
Period of time in question
Begin Date 07/19/96 Time 05:37 (GMT)

Discussion of Problem:
It appears that the pressure sensor on this sonde 'jumped' immediately after
launch from the surface value of 941.8 hPa to 914.0 hPa. This could result
from mechanical shock during launch. In any event, the pressure values
throughout the sounding are incorrect, as will be the altitude, and
ascent rate values.
Other observations/measurements impacted by this problem:
None
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
Flag data. |
