NOAA G-IV ERROR SUMMARY

HURRICANE 2007

Dist. in Gulf of Mexico

Flight ID: N070920

Sensor or system	Number or Name

INE	(for wind derivation)	VEW_PITR, VNS_PITR

Accelerometer	ACINS_PITR

Temperature Probe	AT3

Dew Point Probe	DPRC

Static Pressure	PS2M

Dynamic Pressure	QC2M

Attack Angle	AKRD1

Slip Angle	SSRD1

Vert. Wind	PALT

Constants File 49cal071

Project Directory	/proj/706

Local surface observation not current or unavailable.

Take off: 1728Z Land: 0131Z

Notes:

There were no data gaps.

The Total Temperature #2 (TT2) probe was not available for this mission.

Dynamic slip pressure #1...DBP1...exhibited dropout from 214239Z – 214247Z.

This did have a minor impact on the horizontal and vertical wind data during this time frame.

Dynamic slip pressure #2...DBP2...had erroneous data from 211115Z – 010840Z.

Both dewpoint sensors were balanced shortly after the aircraft reached 41000 feet.

For DPR the sensor was balanced twice between 184915Z – 185720Z, and for DPL it was balanced once between 185834Z – 190225Z. The balancing generated erroneous data over these time periods.

All other instruments worked optimally during the flight.

Thirty-five (35) drops with 32 tempdrop messages successfully sent to NHC and made it into the 21/00Z model run. No drop was made at point 33 due to severe thunderstorms present at that location.
