stratum exceeds 100 mb. between the surface and 400 mb., 
50 mb. between 400 and 100 mb., and25 mb. between 100 mb. 
and the termination, the data within the stratum will be clas- 
sified missing. When it does not exceed these limits, the 
possible error will be computed as follows: Project a line 
following the trend of the last good temperature trace to the 
level of the first good temperature trace above. Likewise, 
project a line following the trend of the first good tempera- 
ture trace down to the levelof the last good temperature trace 
below. If the difference between the temperature atthe top or 
bottom (use the point of least difference) of the missing 
stratum and the projected line is 1°Cor less, classify the data 
in the stratum as accurate. If the difference is more than 1°C 
but not more than 3°C, classify the stratumas doubtful. If the 
difference is more than 3°C, classify the stratumas missing.

Figure B4-8. Classification of Shallow Strata of Missing Temperature. 
Sieg) 
The stratum, Aj to A2, is classified as accurate, (less 
than 1°C at Aj). The stratum, Bg to Bj, is classified 
as doubtful,(more than 1°C but not more than 3°C at Ba). 
The stratum, Cg to Cj, is classified as missing, (more 
than 3°C at C9).
