Data Transfer Included in WeatherNet after converting to
an interactive GRIB format GRIB data format reduced size of data
transfer; Interactive data selection allows user to
customize product request to their specific area of geographic interest.

Data Transfer Net effect of WeatherNet integration and
conversion to GRIB on satcomm download times:
QuikScat GRIB covering NE Pacific Globalstar: 20 seconds Iridium: Just under 1 minute Inmarsat, MSAT: Just over 1 minute
As opposed to minimum 5 to 10 minute satcomm connect to retrieve QuikScat bmps from http://manati.orbit.nesdis.noaa.gov/quikscat/

QuikScat usage in MWXC Routing QuikScat data ‘amazingly precise’ when validated against in situ observations by
client vessels Squall activity which is very important to the at-sea sail cruiser is readily
identified in QuikScat Not well depicted in model data or other analysis/forecast products
