Daily Variables:
23 Aug 1995 to Present:
Total and max daily incoming solar radiation
Time of max
High Resolution Variables:
23 Aug 1995 to Present:
Total incoming solar radiation in megaJoules per meter squared per 15 minutes
Sensor height: 627 cm
Notes: Max solar radiation is maximum rate of incoming solar radiation as
watts per meter squared. All MAXSOLAR values were originally collected as
Langleys per minute from 23 Aug 1995 to 26 July 2007 were converted to
watts per meter squared. The time of max is accurate to the minute.
TOTSOLAR values are megaJoules per meter squared over the given time interval.
Values were originally collected as total Langleys over the given time interval from
23 Aug 1995 to 26 July 2007 but were converted to megaJoules per meter squared.
Conversions occurred in Nov 2009.

Notes: Max solar radiation is maximum rate of incoming solar radiation as
watts per meter squared. All MAXSOLAR values were originally collected as
Langleys from 10 May 1972 to 8 May 2007.
TOTSOLAR values, originally collected as total Langleys over the given time interval
from 10 May 1972 to 8 May 2007, were converted to megaJoules per meter squared.
Conversions occurred in Nov 2009.
Before 07 Jul 1988, max solar radiation rate (now watts per meter squared)
was originally collected as total langleys per minute, but was based on the hour with
maximum total langleys divided by 60. The time of maximum is the hour with the
highest total incoming solar radiation.
After 07 Jul 1988, max solar radiation rate (now watts per meter squared)
was originally based on total langleys per minute, the maximum is based on
one minute, and the time of max is accurate to the minute.
Much of the incoming solar radiation data from the 1970's is estimated.
