New/recent activities Suggested hot MSPS/SPS
test with GOES-12 data via GOES-11. Invested
GOES-11 imager and sounder data while it was out
of storage. Working with a grad student on
turbulence Asked to be on the GOES-R Calibration
Steering Committee Several posters at the 13th
Satellite conference Helped (with an undergrad)
to build a GOES-8 web page as suggested by
Colleen Hartman. Organizing (with Andy) the 4th
NOAA hyperspectral workshop next week in
Madison 3rd GOES-R Users Conference (brochure,
committee, speaker, session chair, poster chair,
poster presenter, etc.)

Moisture Weighting Functions
High spectral resolution advanced sounder will
have more and sharper weighting functions
compared to current GOES sounder. Retrievals will
have better vertical resolution.

Data compression group accomplishments

• Recent compression research advancements include
• Improved lossless compression ratio using
  predictive schemes with spectral re-ordering and
  wavelets math (from 2 to 2.21 with brightness
  temperature units) done by CIMSS at Univ of Wisc
• Principal Component (PC) work continuing with
  AIRS data by ORA
• Impressive lossless compression ratio 31 using
  math of Empirical Mode Decomposition (EMD) in
  digital counts by the CREST at CCNY. (Recall that
  when the data compression group was first formed,
  the best lossless compression ratios hoped for
  were 21.)
• Impressive lossless compression ratio 31 using
  predictive vector quantization (PVQ) by CIMSS.
  This 3.31 ratio can be compared to 2.31 for
  JPEG200.
• Each group using common data-sets for
  comparisons. These data-sets have been made
  freely available.
