The NOAA National Weather Service MicroART upper air system at Fort 
Worth, Texas (WMO # 72249), will be decommissioned on or about November 
30, 2007, and installation of the new Radiosonde Replacement System 
(RRS) will begin. No upper air observations will be provided from this 
office while RRS is being installed.
Beginning December 10, 2007, or shortly thereafter, upper air 
observations will be issued using the RRS and GPS Mark IIA Sippican 
radiosondes.
Please update your databases.
