RELEASE AND RECORDER RECORD 
Determine from the recorder record the point at which 
each significant level is required (see Fig. B4-10). Draw 
a horizontal line on the recorder record through the points 
representing the significant levels. Evaluate the temper- 
ature representing (A) the temperature ordinate and (B) 
the ordinat» where the dashed line intersects the signifi- 
cant level. 
Plot the temperature (B) from the dashed-line ordinate 
of the recorder record on the dashed line of WBAN-31( ) 
and read the pressure. This is the pressure corresponding 
to the temperature ordinate of the significant level and 
should be used without respect to the pressure calibration 
chart. 
Plot the temperature (A) of the significant level at this 
pressure on WBAN-31( ) and enter both temperature and 
pressure in the appropriate data blocks. 
If the stratum is 50 mb or less consider the relative hu- 
midity accurate (see §B4-7.5.2). If the stratum is greater 
than 50 mb consider the relative humidity as missing.

NOTE: This does not take into consideration that the stratum 
could be isothermal. In that specific instance or if the lapse 
rate was shallow, the upper limit could be plotted ten ordinates 
(or any convenient value) colder or warmer than the lower 
limit.
