Notes:

There were several time/data gaps during this flight which occurred from 155501Z-155510Z, 154507Z-
154510Z, 170801Z-170810Z, and 203622Z-203630Z.

The King liquid water sensor was inoperative throughout the flight.

Altitude from inertial one and two were both inoperative throughout the entire flight.

Temperature and dewpoint values from sensor number 3 are also erroneous.

From takeoff through 124640Z data from radar altimeter 232 was substituted into radar altimeter 159.

Data from dewpoint sensor number two was substituted into sensor number one from 130801Z-142258Z, 195837Z-200443Z, and from 201352Z-211105Z.

There were numerous times during the flight where the dewpoint temperature exceeded ambient temperature resulting in RH>100%. This was likely due to rain, a wet-bulb effect on the total temperature sensor, and/or an artificial warming of the dewpoint sensor as it tried to burn off excess moisture. No edits were made to the data to correct this.

Otherwise, all sensors worked optimally during this flight.

SPECIAL NOTE!!!	Locations 80, 81 and 82 of record five on the standard tape contain

vertical ground, vertical air and vertical speeds, respectively, computed

using Dave Jorgensen's vertical wind algorithm.

It is recommended that these values be used for vertical wind analysis.
