G-IV mission data already included in Models..

The models already have included some of the G-IV mission data. In fact, this is the lowest Lat. mission ever flown. Please see:
ZCZC MIATCDAT4 ALL
TTAA00 KNHC DDHHMM
HURRICANE IVAN DISCUSSION NUMBER 20
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 AM EDT TUE SEP 07 2004

A NOAA GULFSTREAM-IV JET PERFORMED A SURVEILLANCE FLIGHT AROUND THE
PERIPHERY OF IVAN LATE YESTERDAY EVENING WHICH HAD A SIGNIFICANT
IMPACT ON THE 00Z MODEL RUNS. MOST OF THE NHC MODEL GUIDANCE IS
TIGHTLY CLUSTERED ABOUT A WEST-NORTHWESTWARD MOTION WITH A GRADUAL
DECREASE IN FORWARD SPEED THROUGH 72 HOURS AS IVAN MOVES AROUND THE
SOUTHWEST PERIPHERY OF THE STRONG SUBTROPICAL RIDGE TO THE NORTH OF
THE CARIBBEAN ISLANDS. HOWEVER...AFTER THAT THE MODELS BEGIN TO
DIVERGE ENOUGH FOR ALREADY STORM WEARY PEOPLE IN FLORIDA TO BE
CONCERNED ABOUT.

I know that is from yesterday, people were saying that there was no G-IV mission data in the models and that is not true. I was simply referencing mention of this by the NHC yesterday morning..

Makes one wonder if the GIV data is hurting or helping the analysis depending on what side of the bed you sleep on.

the data is good then it can only help the forecast problem.
