The CoastWatch validation system is an interactive, menu driven, image and data processing system. The National Centers for Environmental Prediction (NCEP) provides the buoy data used in the
matching procedure. These data are placed in the buoy data file four times a day. The buoy data
file also gives the current NOAA moored buoy locations, so an analyst can overlay the buoy positions
on the AVHRR imagery. AVHRR imagery is in the CoastWatch format and images are archived at the NOAA
Satellite Active Archive (SAA). The main input for this long-term validation system is the Target Match
File (TMF). The TMF is generated by extracting 15 by 15 pixel array targets of the CoastWatch imagery
(i.e., mapped full-resolution AVHRR HRPT imagery including all five channels, cloud masks, and SST)
centered at NOAA moored buoy positions on the NOAA/NESDIS CEMSCS main frame computer.
The Marine Observing Systems Team maintains POES SST validation.  |
