[McIDAS #WIM-982947]: Opinion Question

Hi Rod,

re: what are the times of the two images?
> They are the same time 20:25.

Hmm...

re:
> Weird???? Right?

I think so, but it depends on what the effective radius image is
really telling us.

Question:

- how do the GR2 and 10.7 um IR images compare side by side for
  20:25?

> PRO=MERC RES=6

Questions:

- does LOC/AREAS.3003 already exist when you run this?

  If yes, try deleting the file first:

LWU DEL AREA3003
IMGCOPY G13/IR27APR11 LOC/AREAS.3003 TIME=20:25 LAT=30:00 86:30 SIZE=320 320 
PRO=MERC RES=6

- What happens if you change PRO=MERC to PRO=RECT?

What stuck me just now is the effective radius image looks like it is in the 
original
satellite projection which means that the PRO=MERC RES=6 keywords had no effect.

> IMGDISP LOC/AREAS.3003 1 LAT=30:00 86:30 EU=IMAGE
> MAP STATE=MS AL GA COUNTY=ALL MCOL=8
> MAP FILE=OUTVHPOL MCOL=1

So, you have the IR image; how does it compare to the GR2 one?

re:

> IMGREMAP G13/ERAD27APR11 LOC/AREAS.3103 TIME=20:25

> MAP LALO -2 INT=5 5 STATE=MS AL GA COUNTY=ALL MCOL=8
> MAP FILE=OUTVHPOL MCOL=1

OK, this is the effective radius image that you are comparing to 
the GR2 one?

re:
> IMGFILT LOC/AREAS.3003 LOC/AREAS.3103 LOC/AREAS.3203 FILTER=DIS 0 255 185 255 > 0
> IMGDISP LOC/AREAS.3103 3 LAT=30:00 86:30 EU=CLW3 SF=YES
> MAP LALO -2 INT=5 5 STATE=MS AL GA COUNTY=ALL MCOL=8
> MAP FILE=OUTVHPOL MCOL=1

Or, is it this image that you are comparing to the GR2 one?

re:
> IMGPROBE LIST POINT MODE=N LATLON=34.689243 88.234695
> IMGPROBE LIST POINT MODE=N LATLON=34.685452 87.354070

> IMGPROBE STAT BOX OUTLINE=YES COLOR=2 MODE=N LINELE=61 121 F PLACE=ULEFT 
> SIZE=11 28 EXCLUDE=0 1-184

These are irrelevant for the current discussion...

Cheers,

Tom
