GOES Data Collection System

For STIWG May 2005

There is a current action to add the following new category of Road Conditions to the Physical Element codes (PE codes) of SHEF….

KC = Road Surface Conditions, where:
        0=DRY
        1=DAMP
        2=WET
        3=ICE
        4=SALT
        5=FREEZING WET
        99=UNKNOWN
KE = Error Check Value
KF = Road Surface Freezing Temperature (Degrees F,C) (will = 9999 when salt content =0)
KH = Road Surface Water height (IN,MM)
KS = Road Surface, Salt Content  (%)  (will = 9999 when salt content =0)
KT = Road Surface, Temperature (Degrees F,C)

PE codes below in Bold have been approved for use, but have not yet been added to the “Official SHEF Handbook” document.
