NOTE: 1988 Epply calibration: 1mv=99.6 watts/sq. meter     1995 Epply calibration: 1mv=94.8 watts/sq. meter     All originally listed values (1993-1997) and 1998 values through July 6 1998 have, for the above table, been adjusted to the 1995 calibration by multiplication by 0.9518.  The logger program was changed on July 7 1998. It now uses the 1995 calibration. The 2002 cal was 1mv=94.3 watts/sq meter.
