The ANL tethersonde was located at 37.65 N 96.73 E at the Leon
main site. File names are in form of ssddhhmm where 
ss = site (le)
dd = day of month (October 99 assumed)
hh = hour (GMT)
mm = min of approximate beginning of run

 The raw data consisted of pressure, dry bulb temperature,
wet bulb temperature, wind speed and wind direction measured at
roughly 10 s intervals.  The data files consist of 2 header lines
followed by the data

1st hdr line:
STUDY CASES99 SITE TWR17 TET 700.540 4168.654 date time
*** the only parts of this line that change are date and time***

2nd hdr line:
   DATE   TIME  Pr(mb)  Ht(m)    Td(C)    Tw(C)  RH(%)  VAP(hPa) R(g/kg)  PT(K) SPEED(m/s) DIR
*** all of these should be self explanatory ***

data
***date is yymmdd***
***time is hhmmss (GMT)***
***other fields are obvious***
***except the last, which is the direction of the tethersonde***
***H = Hold   ***
***R = Raise  ***
***L = Lower  ***

final line is 88888888

Best attempts were made to eliminate data when tethersonde was descending or
rising rapidly.
