The radiosonde readings will automatically print out in 5-second intervals in the first few minutes of the sounding, as shown in table 1-1, and then change to IO-second  intervals. All data are automatically processed. An increase in  pressure  is  interpreted  as  a  balloon  burst,  and  the sounding  will  automatically  terminate.  Failure  of  the pressure  to  decrease  is  Interpreted  as  a  “floating balloon,”  and  this  will  also  terminate  the  sounding. Other factors that will cause sounding termination are pressure  values  missing  for  more  than  10  minutes, temperature data missing for more than 8 minutes, and humidity data missing for more than 6 minutes. Manual termination  of  the  sounding  may  be  made  via  the command entry keys. All  U.S.  synoptic  upper-air  sites  arc  required  to launch a second radiosonde should the first radiosonde fail  to  reach  a  height  of  at  least  400  hPa.  Navy  and Marine  Corps  upper-air  soundings  conducted  for operational support are exempt from this requirement. All  raw  data  printed  out  during  the  flight  should  be scanned  for  validity.  Continuous  output  of  erroneous data  will  obviously  necessitate  another  launch.  Any periods of doubtful data should be encoded as such on the  transmitted  message.  Prolonged  periods  of  doubtful or  missing  pressure,  temperature,  humidity,  or  wind data   may   also   Invalidate   the   sounding.   Criteria   IS outlined in chapter 3 of the FMH-3. CAUTION Pressing  the  "reset"  command  at  any  time will  completely  dump  all  sounding  data  and reset the program to the beginning of the set-up routine. After the sounding is terminated, the system may be directed  to  print  a  listing  ("LIST"  program)  of significant levels (table 1-2), which were selected by the computer  for  changes  in  temperature,  humidity,  or winds, and a listing of all mandatory levels (table 1-3). In  addition,  the  "TEMP"  program  will  produce  a printout   of   the   TEMP   coded   report   (table   1-4). Abbreviations on the significant level printout indicate the  reason  the  level  was  selected,  such  as  T  for temperature, U for relative humidity. TR for tropopause. F  for  wind  speed,  D  for  wind  direction,  and  MV  for maximum wind Table 1-1.—-MRS Sounding Automatic Data Printout 1-11
