The NWS upper air office at Koror in the South Pacific (WMO# 91408),
transitioned from the Vaisala RS80-57H radiosonde to the Lockheed Martin
Sippican B2 radiosonde on 00:00 UTC January 1, 2010.
The B2 radiosonde has been used in the NWS Upper air network since June,
1997. Unlike the Vaisala RS80-57H, a solar/IR radiation temperature
correction _is not_ applied to the B2 data at the station prior to
dissemination.
Questions on the radiosonde transition should be directed to Joseph
Facundo, Observing Systems Branch Chief, at Joseph.Facundo@xxxxxxxx
