SGP/EBBR/E26 - Right Air Temperature Malfunction

The right air temperature probe malfunctioned continuously during the
periods of time indicated above as continuous.  On May 16, 1995, by 1900 GMT,
the probe was replaced (old S/N 92007, new S/N 92013).  There was a complete
loss of data between 1200 and 1900 GMT as Site Operations repaired a corroded
battery terminal.  For several days the right air temperature probe worked
well.  However, between May 24 and 28, the right air temperature probe
malfunctioned continuously again.  The right air temperature probe
malfunctioned intermittently between May 28 and June 1, as well as
during short periods on June 5 and 6.  The cause of these latter periods is
unknown; the time periods do not correspond with any Site Operations
activities.  During the intermittent periods the data that is not offscale
should be viewed as questionable, as it is not always easy to detect what
effect the malfunction might have had on that data.

The malfunction of the right air temperature probe results in incorrect Bowen
ratio, sensible heat flux, and latent heat flux during the periods indicated.

The data values that are affected are:

5 minute:  tair_top, tair_bot

15 minute: tair_r

30 minute: tair_top, tair_bot, bowen, e, h.
