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: FNEXRAD - NEXRAD Level III composites: Product Res Cod Type Form Status --------+------+----+-------------------+------+---------------- National 1 km N0R base reflectivity GINI existing product National 2 km N1P 1-hour precip.

all products are updated every 5 minutes - all GINI images are PNG compressed - further information including sample displays of these Level III composites can be found in: http://www.unidata.ucar.edu/data/radar.html#fnexrad UNIWISC (aka MCIDAS) -

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: Satellite Image Sectors: RTIMAGES/ANTARCTICVIS Antarctic Visible composite RTIMAGES/ANTARCTICWV Antarctic Water Vapor composite RTIMAGES/ANTARCTIC Antarctic Thermal Infrared composite RTIMAGES/ANTARCTICIR Antarctic Thermal Infrared composite RTIMAGES/ARCTIC-VIS Arctic Visible composite RTIMAGES/ARCTIC-IRS Arctic Shortwave Infrared composite RTIMAGES/ARCTIC-WV Arctic Water Vapor composite RTIMAGES/ARCTIC-IR Arctic Thermal Infrared composite RTIMAGES/ARCTIC-IRL Arctic Longwave Infrared composite RTIMAGES/GE-1KVIS GOES-East HiRes Visible RTIMAGES/GE-VIS GOES-East Visible RTIMAGES/GE-39 GOES-East Shortwave Infrared RTIMAGES/GE-WV GOES-East Water Vapor RTIMAGES/GE-IR GOES-East Thermal Infrared RTIMAGES/GE-CO2 GOES-East Longwave Infrared (CO2) RTIMAGES/GW-VIS GOES-West Visible RTIMAGES/GW-39 GOES-West Shortware Infrared RTIMAGES/GW-WV GOES-West Water Vapor RTIMAGES/GW-IR GOES-West Thermal Infrared RTIMAGES/GW-CO2 GOES-West Longwave Infrared (CO2) RTIMAGES/GEW-VIS GOES-East/West NH Visible composite RTIMAGES/GEW-39 GOES-East/West NH Shortwave Infrared composite RTIMAGES/GEW-WV GOES-East/West NH Water Vapor composite RTIMAGES/GEW-IR GOES-East/West NH Thermal Infrared composite RTIMAGES/GEW-CO2 GOES-East/West NH Longwave Infrared composite RTIMAGES/GLOBAL-WV Global Rectilinear Water Vapor composite RTIMAGES/GLOBAL-IR Global Rectilinear Thermal Infrared composite RTIMAGES/MOLL-WV Global Mollweide Water Vapor composite RTIMAGES/MOLL-IR Global Mollweide Thermal Infrared composite RTIMAGES/MDR Manually digitized radar GLOBAL/WVCOMP Global Rectilinear Water Vapor composite GLOBAL/IRCOMP Global Rectilinear Thermal Infrared composite GLOBAL/MOLL-WV Global Mollweide Water Vapor composite GLOBAL/MOLL-IR Global Mollweide Thermal Infrared composite NEXRAD Level III National Composites: NEXRCOMP/1KN0R-NAT 1 km N0R US Base Reflectivity Composite NEXRCOMP/2KN1P-NAT 2 km N1P US 1-hr Precip.
