Numerical Weather Prediction Initialization/Forecast Evaluation

The model availabilty varies with each model. The ETA is the earliest followed by the AVN. The CMC and NOGAPS are the latest. ALSO, MRF is no longer available and the NGM is not being used any more.

Cloud Track/Water Vapor Satellite Derived Winds:
    These data are produced at the  Cooperative Institute for Meteorological Satellite Studies (CIMSS)  at the University of Wisconsin-Madison. These winds are calculated by tracking the motion of finite cloud elements over a short period of time. Please see their web page for further details about this data set.

Aircraft Communications, Addressing, and Reporting System (ACARS):
    This data set is provided by the  Forecast Systems Laboratory in Boulder, CO. Several airlines have equipped their aircraft with meteorological instruments that are capable of measuring windspeed and direction, and temperature. Some also provide dew point temperature.

Surface, Ship, and Buoy Observations:
    These data are those which are received from the National Centers for Environmental Prediction (NCEP) .

Radiosonde Data:
    These data, like the surface data above are also received from the National Centers for Environmental Prediction (NCEP) .

Precipitable Water (derived via satellite):
    This data set is also a product received from the Cooperative Institute for Meteorological Satellite Studies (CIMSS) group at the University of Wisconsin-Madison.

Scatterometer Winds (derived via satellite):
    This data set is a product received from the  Ocean Physical Processes Team  at NESDIS/NOAA in Camp Springs, Maryland. The satellite is the ERS-2 satellite maintained by the  European Space Agency and the algorithm used to produce the winds is CMOD4.
