SGP/EBBR/E13 - Low Battery Voltage and AEM Left on Manual

Low battery voltage caused some data values to be incorrect beginning at
1500 GMT on August 1, 1995.  The data should be carefully inspected to
determine which values are incorrect.

During replacement of the battery at the Central Facility EBBR on August
1, 1995, the AEM exchange toggle switch was left in the manual position,
which caused the right aspirator to remain in the home position until the
switch was correctly placed in the exchange position at 1616 GMT on August
2, 1995.  All 5, 15, and 30 minute values of temperature, relative humidity
, vapor pressure, bowen, e, and h are incorrect during the period. 15 and
30 minute values are also incorrect at 1630 GMT.
