An operational notice about WCOSS.
WCOSS is the Weather and Climate Operational Supercomputing System that runs NWS forecast models.
Balloon reports 00Z NAM RAOB RECAP...
Twice a day, NWS and partner agencies release weather balloons that carry a radiosonde — a small instrument package that radios back temperature, humidity, pressure and wind as it climbs. Those soundings are one of the main ingredients in a forecast model’s starting conditions. This section is the roll call of stations that had a problem for the 00Z run of the NAM.
37 stations were flagged: 5 sent no usable sounding at all, 8 reported a numeric status code, 24 were missing part of the transmission. A handful of gaps is normal and is not by itself a sign of a forecast problem — the models are built to work with an incomplete picture.
