The NOAA National Weather Service MicroART upper air system at
International Falls, Minnesota (WMO# 72747), will be decommissioned on
or about May 15, 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 25, 2009, or shortly thereafter, upper air observations
will be issued using the RRS and GPS Mark IIA Sippican radiosondes.
