GOES-10 coverage inclusions
On Tuesday, January 30 Unidata realigned the
satellite dish at the NCAR Mesa Lab and successfully began
ingesting GOES-10 (commonly referred to as GOES-South in Unidata)
imagery using equipment that had been excessed by various groups in
NCAR/UCAR and the Unidata community, and McIDAS SDI software licensed
from the Space Science and Engineering Center (SSEC) of the University
of Wisconsin-Madison.
On Wednesday, January 31 GOES-10 imager sectors were integrated into
the Unidata-Wisconsin datastream (IDD feedtype UNIWISC)
GOES-East (currently GOES-12) products for the benefit of the US and
international Unidata community, especially universities in Latin
America.
The pictures below show representative coverage being provided by
GOES-10 and the results of their inclusion in Unidata-Wisconsin
GOES-East data products:

NOTE(s) on Figure 2 composite imagery:
the image composites represent a combination of GOES-East and
GOES-10 images. The composites are created every half hour
using the GOES-East North American, North American Extended, South
American, and/or full-disk imager scans. GOES-10 imagery is used
in regions where GOES-East data is not available and when the
GOES-10 scan time lies within a half-hour window centered on the
GOES-East scan time.
the wavelengths of the Water Vapor channels on GOES-East and
GOES-10 are slightly different: 6.5 um for GOES-East; 6.8 um
for GOES-10. This results in a noticable difference in the sector
portions represented by each satellite.
since the longwave IR channels provided by GOES-East and GOES-10
are not compatible (GOES-East is 13.2 um; GOES-10 is 12.0 um),
no GOES-East/GOES-10 compositing is attempted. The scan coverage
presented for the 13.2 um channel represents the GOES-East North
American, North American Extended, South American, and/or full-disk
scans.
the jagged edges seen at the southern earth/space boundaries in
each composite were left intact as a visual reminder that the
southern portion of the composite has been remapped into the
projection of the northern scan.
