• Applications of GSIP Data
• Coral Reef Watch (CRW) combines insolation (PAR)
  from GSIP-fd with operational thermal stress
  products in an algorithm based on bleaching
  physiology.
• NCEP validates NWP Model predicted fields of
  cloud properties, radiation fluxes and land
  surface skin temperature with GSIP-fd.
• Woods Hole Oceanographic Institute (WHOI) uses
  radiation data in estimating heat flux components
  over the coastal ocean to drive ocean circulation
  models and the PAR data to drive coupled ocean
  biophysical models.
• Board Decision
• System is operational with improvements
  added (2-3 month).
• Data Access
• Real-time data now available on
  experimental processing site at
• ftp//ftp.star.nesdis.noaa.gov/pub
  /smcd/gsip/
