Most of the NOAAPORT satellite images are relatively small in size
(1.6MB) and could be sent over IDD. The problem child is the 1km visible
which cannot be sent over IDD. What I've done here is to resample the
image back to 4 km (1.6MB) and use this image. I have a program to do
the resample. The potential of 4 images an hour at 4km is better than
nothing at all.
I would send to all sites:
WMO Chan Type Res Size #/hr
TIGN01 2/3 Vis 8 1.5M 2 National composite (East+West covers
US+HI+AK)
TIGN02 2/3 IR11 8 1.5M 2 National composite
TIGN05 2/3 WV 8 1.5M 2 National composite
TIGF01 2/3 Vis 24 514K 2 North Hemisphere composite (East+West)
TIGF02 2/3 IR11 24 514K 2 North Hemisphere composite
TIGF05 2/3 WV 24 514K 2 North Hemisphere composite
Total: 14MB/hr
I would send to eastern sites:
TIGE01* 2 Vis 4 1.6M 4 CONUS East Vis resampled to 4 km
TIGE02 2 IR11 4 1.6M 4 CONUS East IR 11 micron
Total: 12.8MB/hr
I would send to western sites:
TIGW01* 3 VIS 4 1.2M 4 CONUS West Vis resampled to 4km
TIGW02 3 IR11 4 1.2M 4 CONUS West IR 11 micron
Total: 9.6MB/hr
You could resample the Vis images to 2km and get images around 6.5MB in
size. This could be sent within reason to some sites. Sending the 26MB
1km files, 4 per hour is beyond most sites capabilities.
You could also argue that the McIDAS area files already provide most of
this so why send other than to get the time resolution.
