Data collection & web-access details:

Data is continuously collected from USSCMC's weather-sensor-cluster (at the end of the USSCMC dock) by their Davis Instruments Vantage Pro2 weather station.     The Vantage Pro2 also sits in an office window on the second floor of the Sailing Center and displays all of it's data to anyone who wants to look through the window at the weather station.    (wind information plus outside temperature data) is copied onto USSCMC's Dell laptop computer, from their Vantage Pro2 weather station every 5 minutes.     The "Davis Instruments WeatherLink (version 5.7) software" then creates the graphics you see on this web-page.  

Those graphics files are then uploaded to Bill Schell's web-server (at "Hurricane Electric" in Fremont, California) every 5 minutes.

The data-graphics you see come to you from a fairly simple ...html wrapper program as a single web-page.  Additional pages to cover both 'further' and 'notes' subjects are hosted in the same directory on the same server.

Data should always be availble on a 24 x 7 basis (every 5 minutes) UNLESS someone at the USSCMC un-plugs any of several cables or dis-ables the software, or - perhaps - even turns off the power for their Dell laptop computer.

other notes:

The sensor-cluster is mounted on an old (sailboat) mast bolted onto the end of the dock at the USSCMC.   The 'cluster' of the sensor-collection group is approximately 30 feet (about 9 meters) off the water - and the water level here is 'roughly' (within a half-foot or so) of 'Mean Sea Level' (MSL).  Even though this sensor-cluster is mounted on a sailboat mast bolted to the end of the dock, the sensor-cluster does 'wobble' about 1"-3" in a stiff breeze (20 knots).

Latitude is approximately:     North 27.2303 degrees
Longitude is approximately:   West 80.2155 degrees

The sensor cluster is on the west-side of the Indian River (on the USSCMC property-dock), approximately 1.6 miles south of the Jensen Beach Causeway.  Further this site is 'roughly' 1.8 miles from the Atlantic Ocean - the bearing from this site to the Atlantic Ocean is roughly 065 degrees.

ONE CAUTION: The wind-sensor (both direction and speed) should be 'very accurate' for winds from about 340 degrees to about 160 degrees.  Less accurate readings will be 'about' 160 to about 340 degrees.  (roughly the western-half of the compass rose).  The 'accurate' portion of the compass rose is roughly equivalent to the 'prevailing' direction(s) and speeds of wind in this part of Florida.

Sensors collect information about: wind direction, wind speed, outside temperature, outside humidity, rain and other parameters.   Other data are typically calculated in either the Vantage Pro2 weather station and/or inside the Dell laptop computer via the Davis Instruments "WeatherLink (version 5.7) software".
