Users of Unidata IDD FNEXRAD and UNIWISC datastream products:
At or shortly after 0 UTC on Saturday, March 21 (18:00 MDT Friday),
the contents-of the Internet Data Distribution FNEXRAD (NEXRAD Level III
national composites) and UNIWISC (aka McIDAS, satellite imagery sectors)
datastreams will be updated with new products.
The previous source (creation point) for the FNEXRAD products was
motherlode.ucar.edu, and the source (creation point) for the UNIWISC
products was unidata2.ssec.wisc.edu. Both datastreams are now being
created in a 64-bit CentOS 6.5 VM in the Amazon EC2 cloud.
The following is a brief overview of the contents of each datastream
with special emphesis on new or altered products:

Notes:
- update cycles vary by product
- all images are in a PNG-compressed McIDAS AREA format
- Global Mollweide WV and IR composites are now higher resolution and
larger in size
- further information including sample displays of these satellite image
sectors can be found in:
http://www.unidata.ucar.edu/data/datastream.html
Potential impacts to end-users:
- the Global Mollweide composite products will be 4x the size/double
the resolution of the ones that have previously been included
This will likely require updates to users' automated processing
routines (e.g., IDV bundles, McIDAS BATCH/MCB files, shell scripts, etc.).
- McIDAS ADDE dataset names on Unidata-maintained servers (e.g.,
ADDE.UCAR.EDU, ATM.UCAR.EDU, ADDE.SSEC.WISC.EDU, LEAD4.UNIDATA.UCAR.EDU)
will be updated to the following:

Notes:
- RTIMAGES/ANTARCTICIR serves the same data as RTIMAGES/ANTARCTIC;
RTIMAGES/ANTARCTICIR is the new, preferred name
- RTIMAGES/GLOBAL-WV serves the same data as GLOBAL/WVCOMP;
RTIMAGES/GLOBAL-WV is the new, preferred name
- RTIMAGES/GLOBAL-IR serves the same data as GLOBAL/IRCOMP;
RTIMAGES/GLOBAL-IR is the new, preferred name
- GLOBAL/MOLL-WV serves the same data as RTIMAGES/MOLL-WV;
RTIMAGES/MOLL-WV is still the preferred name
- GLOBAL/MOLL-IR serves the same data as RTIMAGES/MOLL-IR;
RTIMAGES/MOLL-IR is still the preferred name
- the GLOBAL/WVCOMP and GLOBAL/IRCOMP images that have been served
by the Unidata-operated ADDE server adde.ucar.edu will be reduced
from previous instances by a factor of about 5 (20 km versus 4-5 km
previously)
