Upper-air verification
Raob verification (For research and operational global/regional models, global/N.Amer RAOB data)

Raob verification (For operational models only - for N.America only)
NCEP statistics based on isobaric files, verified against quality-controlled RAOBs (mandatory levels at and above 850 mb)

Aircraft verification
Statistics based on AMDAR data. Available every hour but highly non-uniform in space and time.

Global model - grid verification - Anomaly correlation statistics for FIM and GFS.

Cloud verification
Ceiling hourly statistics verified against METAR data.

Visibility statistics verified against METAR data.

Cloud and Solar Insolation verification against GSIP, SURFRAD/ISIS, and METARS.

Surface verification
