verted to windspeed and direction in a manner
similar to that when the balloon was observed
visually (a above).
c. Surface Atmospheric Pressure. Surface
atmospheric pressure is obtained through obser-
vation of readings obtained from the barometer
mospheric pressure directly in millibars ML102
B, D, E, F, and G) and inches of mercury
(ML-102-B, -E, -F).
d. Surface Wind Direction and Speed. Surface
wind direction and speed are obtained through the
observation of indications on the anemometer (fig.
dications of windspeed in knots and the compass
indicates direction of the wind.
e. Surface Temperature. Temperatures are ob-
tained through the use of the general and/or
tropical thermometers (fig. 1-18).
f. Surface Relative Humidity. Data required
for the computation of surface relative humidity
is obtained through the indications provided by
the psychrometer (fig. 112).
