Rapid Scan and Super Rapid Scan schedules are not affected and will be available during this period. Routine scanning operations will also be available should conditions warrant. This GWINDEX (GOES rapid scan Winds EXperiment) research request is in support of the Pacific Landfalling Jet Experiment (PACJET). This experiment will provide not only improved GOES winds product, but also real-time utility to NWS field forecasters and in Numerical Weather Prediction (NWP). **This temporary schedule will be in effect from:** **2145Z on Jan 07, 2002 through 2145Z on March 31, 2002.** **The effected schedule and images are as follows:** Approximately one third of the current Southern Hemisphere Image that are scanned hourly at xx:52 will be replaced with a Pacific US (PACUS) sector. -->*This replacement of the Southern Hemisphere image with a PACUS image will occur every 3 hours at 02:52Z, 05:52Z, 08:52Z, 11:52Z, 14:52Z, 17:52Z, 20:52Z, and 23:52Z.*<-- Therefore, the Southern Hemispheric images at the other hours (00:52Z, 01:52Z, 04:52Z, 06:52Z, 07:52Z, 09:52Z, 10:52Z, 12:52Z, 13:52Z, 16:52Z, 18:52Z, 19:52Z, and 22:52Z) will remain unaffected, as will all of the current Southern Hemisphere imagery scanned at XX:22. Note the missing 03:52Z, 15:52Z, and 21:52Z images due to housekeeping on GOES-10. You may recall the similar test in January-March of 2001. However, during that test, all Southern Hemisphere images at XX:52 were replaced with a PACUS image. This had some unintended negative consequence on some operations, thus the altered proposed schedule for this year. In the event of operational considerations (for example, a tropical cyclone approaching the American Samoa) the current GOES-West scanning schedule can and will be reinstated for the duration of operational needs. The PACJET schedule will be reinstated once conditions warrant. See http://www.ssd.noaa.gov/PS/SATS/GOES/WEST/sched.html for full details on the current scanning strategy and scanning schedule. See http://gale.ssec.wisc.edu/gwindex for information from the previous GWINDEX. If there are any other concerns to this temporary schedule change, please contact me.
