Converter Functions
C1 Converter Module 1 Maps sounding
information from RODF files into
PRET MD files C2
Converter Module 2 Calculates stability
parameters C3 Converter Module 3 Computes
the gradient winds C4 Converter Module 4
Merge GOES/POES MD and GRET/GWIN MD to
make a new
GOES/POES Skew-T MD file that have
information on
retrieval, wind and the stability
parameters. C5
Converter Module 5 Generate the SKEW-T gif and
composite image files

Conclusion

• Timely access to global sounding products via
  the web
• Reused the code (C4 C5) developed within the
  GOES products for the
• POES products
• Modular code was developed for the GOES and POES
  systems to be used
• for other sounding products such as IASI and
  MIRS.
• User familiarity between GOES and POES web pages
