The NOAA National Weather Service MicroART upper air system at White
Lake, Michigan (WMO# 72632), will be decommissioned on or about May 1,
2009, 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 May 11, 2009, or shortly thereafter, upper air observations
will be issued using the RRS and GPS Mark IIA Sippican radiosondes.
