Temperature in degrees Celsius (°C) may be converted to degrees Fahrenheit (°F) as follows:
°F=(1.8×°C)+32
The SI unit for pressure is the pascal (Pa). 1 Pa = 0.0001 decibar (dbar) = 0.001 kilopascal (kPa).
Vertical coordinate information is referenced to North American Vertical Datum of 1988 (NAVD88).
Horizontal coordinate information is referenced to North American Datum of 1983 (NAD83).
Elevation, as used in this report refers, to distance above the vertical datum.
