I decided to send you all a brief summary of the data that were collected
during those hectic two weeks in early September. All of the missions were
accomplished and the imagery is extremely exciting. Thanks once again to
everyone who helped.
SUMMARY OF SPECIAL GOES -9 DATA COLLECTION
DATE JD TIME Satellite collected
3Sep1995 95246-47 1830-1830 UT GOES-9, Sch. A, 15-min., over Pensicola, FL
WEATHER - New convection forms along remnants of a north/south-oriented
land breeze in the central Gulf, and a few weak storms form over southern FL
on the seabreeze.
DATE JD TIME Satellite collected
4Sep1995 95247-48 1830-1830UT GOES-9, Sch. A, 15-min., over Pensicola, FL
WEATHER - Previous day's land breeze in central Gulf of Mexico
continues to form convection. Meanwhile, a land breeze south of Cuba merges
with an island breeze from the Isle of Youth forming new convection over the
channel. There is some weak seabreeze convection in south Florida.
DATE JD TIME Satellite collected
5Sep1995 95248-49 1830-1830UT GOES-9, Sch. D centered at 20N, 65W
1843-0043UT GOES-8, 1-min SRSO at same place
WEATHER - Centered over Hurricane Luis (category 4) just after it hits
Antigua (storm center was about 40 mi NW of island at beginning of
collection). There is a lot of gorgeous mesoscale action in and around the
eye. 24 hours of 1-min collection continues as storm brushes Leeward
islands.
DATE JD TIME Satellite collected
6Sep1995 95249-50 1830-1830UT GOES-9, Sch. C centered at 20N, 65W
WEATHER - 1-min begins with Hurricane Luis as it moves out to sea north
of Leeward Islands, then goes to 15-min overnight and picks up again at dawn
with the storm about 250 miles north of Puerto Rico.

and continues 1-min till nightfall when the storm is about 200 miles
northwest of Bermuda. After 15-min collection all night, the sector goes
back to 1-min interval. By this time storm is ~500 miles north of Bermuda.

Date: Fri, 15 Sep 95 09:39:00 PDT
And here we have the final GOES-9 test series forecast . . .
For the period 1800 UTC on 16Sep through 1800 UTC on 17Sep we would like to
continue with Schedule C, centering over 20N 68W.
Thanks for all your help, and tell all involved that we appreciate their
efforts in helping to assure that this test series was successful.
--------------------------------
Date: Thu, 14 Sep 95 09:51:00 PDT
As per our phone converstation, we would like to initiate a GOES-8, 1-min
SRSO schedule beginning tommorrow, 15Sep at 1943 UTC and continuing through
to 0143 UTC on 16 Sep. The location will be sector #6, which is centered
over Puerto Rico.
--------------------------------
Date: Thu, 14 Sep 95 09:36:00 PDT
As per our phone conversation this morning ... For tommorrow's collection
(which begins at 1800 UTC on 15Sep and goes through 1800 UTC on 16Sep) we
will continue with Schedule C, but move the senter point to 18N, 65W.
--------------------------------
Date: Wed, 13 Sep 95 09:33:00 PDT
As per our phone conversation, we would like to continue with
Schedule C for the period 1800 UTC on 14 Sep through 1800 UTC onb 15 Sep.
The sector center should be changed to 14N, 65W. My guess is that we'll
be tracking this storm up through Jamaica for the rest of the test, since
the mid-latitudes seem to be fairly calm at this point.
--------------------------------
Date: Tue, 12 Sep 95 09:34:00 PDT
First -- as per our phone conversation, tommorrow (i.e., beginning at
1800UTC on 13 Sep) we would like to run Schedule C, centered at 14N, 58W for
a potential named storm approaching the Lesser Antilles
Second -- just got a message from Jamie H. suggesting that the special tests
will be going through Sep 18th. That means our last forecast will be on Sep
16th to cover the period 18UT on the 17th through 18UT on the 18th. Is that
the correct interpretation?
--------------------------------
Date: Mon, 11 Sep 95 10:29:00 PDT
Today's collection (which begins at 1800 UTC, 11 Sep and ends tommorrow
at 1800 UTC on Sep 12) will be schedule C centered at 33 N, 83 W.
The collection which begins tommorrow at 1800 UTC (12 Sep) and ends 1800
UTC on 13 Sep will be schedule B, centered at 34N, 92W.
--------------------------------
Date: Fri, 08 Sep 95 09:40:00 PDT
Gordon - - sorry about refering to today's start time as 12 UT in
yesterday's message. Thanks for catching it. I, of course, meant 1800 UTC
Now, back to business. As per our phone conversation this morning, the
following schedule is set for this weekend.
1800 UTC Saturday (9 Sep) through Sunday 1800 UTC (10 Sep) - - this will be
schedule C centered at 33N, 70 W for hurricane Luis.
1800 UTC Sunday (10 Sep) through 1200* UTC on Monday (11Sep) - - schedule F
which is a 10-min continuous collection over South America using the sector
that you and Jim predefined. THEN from 1200 UTC on Monday through 1800 UTC
we will switch to schedule C centered over 45N and 60 W. For this six hour
period, we will switch the soundings from the F sector to the North
Atlantic.
GUESS - - From 1800 UTC on Monday to 1800 UTC on Tuesday we may want to
stick to 45N, 60W for the first six hours, then switch to another location.
We will plan on running schedule C in any case. More on that Monday
morning when we see where Luis is located.
--------------------------------
Date: Thu, 07 Sep 95 11:12:00 PDT
The collection which begins tommorrow (8 Sep) at 1200 UTC will be the North
Atlantic sector. The schedule will be schedule E, the soundings will be
done over the prescribed N. Atlantic sounding area, and the 1-min imaging
will be centered at 45N, 50W.
Tentatively for the weekend it looks like Schedule C over Bermuda beginning
18 UT on Satuday, Schedule F beginning 18 UT on Sunday, and possibly
Schedule C or D over the northeastern coast of the U.S. on Monday depending
on what Luis does. We will have a final decision by tommorrow morning's
call regarding the weekend, and particularly Monday.
--------------------------------
Date: Wed, 06 Sep 95 10:09:00 PDT
Gordon -- to confirm the plan for the next 48 hours ...
From 1800 UTC today (6 Sep) till 1800 UTC tommorrow (7Sep) we will be
running schedule C which will be centered over 20N, 65W. This is perfect,
because the eye of hurrican Luis is at that exact location.
Beginning tommorrow we will be switching to schedule B. Schedule B timing
will continue throughout the 24 hour period, but the sector center will vary
as follows: for the first hour 1800UTC to 1900 UTC (on 7 Sep) we will
center the imagery at 60N, 110W. After one hour we will switch the sector
center to Washington, D.C. -- roughly 39N, 77W. Then, for the last hour of
the 24 -- that is, from 1700 UTC to 1800 UTC (on 8 Sep), we will again
switch back to 60N, and 110W.
We will talk on the phone tommorrow morning at roughly 11:30 your time
local, to discuss where the sector goes after that, as well as get a
preliminary outlook for the weekend.
--------------------------------
Date: Tue, 05 Sep 95 12:08:45 EST
After coordinating with NWS field sites, it's a go for GOES-8 SRSO
today, Sept. 5, from 1843 UTC to 2343 UTC; sector six or the Puerto
Rico sector will be used.
--------------------------------
Date: Fri, 01 Sep 95 10:22:00 PDT
John P - - We would like to tentatively designate Tuesday, 5 September 1995
an SRSO special 1-minute collection day. The sector would be Sector #6, and
the times would be roughly 1900 UTC through 0100 UTC (6 Sep). There is a
fair chance that we will be calling it off early Tuesday morning, but right
now it looks pretty good.
--------------------------------
Date: Fri, 01 Sep 95 10:03:00 PDT
From Sunday through 1800 UTC on Tuesday, 5 September 1995 we will be running
schedule A which is the so-called "routine mode". As I understand it, we do
not have to supply a sector center for Schedule A.
Beginning on Tuesday, at 1800 UTC, we would like to run schedule D which is
the "Hurricane near Land". This schedule allows near continuous 1-minute
imaging from 1800 UTC on Tuesday to 1800 UTC on Wednesday. Tentatively we
would like the sector to be centered at 65W longitude, 20N latitude, with
the understanding that we can adjust the centering up to 10:00 AM EDT on
Tuesday morning.
