Marble Bar Comparison 4020 raw temperature audit

Station audited 1 January 1910 to 31 December 2003

(See also Marble Bar 4106)


Marble Bar Comparison 4020 maximum temperature audit


At Marble Bar Comparison 4020 from 1 January 1910 to September 1972, whole .0 Fahrenheit degrees represented 35.6% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 5.4% of all maximum temperatures recorded.


1910-1972 represented 66.7% of the time span and had 49.5% of .0C and 21.5% of .5C maximum temperatures within the entire temperature record.


From 1972-2003, maximum temperature recordings of .0 Celsius degrees represented 19.5% of the total and .5C recordings represented 14.1% of the total of all fractions since 1972. Together, .0C and .5C represented 33.6% of all maximum temperatures recorded since metrication.

Marble Bar Comparison 4020 minimum temperature audit


At Marble Bar Comparison 4020 from 1 January 1910 to September 1972, whole .0 Fahrenheit degrees represented 40.6% of all minimum temperatures recorded and .5 Fahrenheit degrees represented 3.4% of all minimum temperatures recorded.


1910-1972 represented 66.7% of the time span and had 50.9% of .0C and 15.8% of .5C minimum temperatures within the entire temperature record.


From 1972-2003, minimum temperature recordings of .0 Celsius degrees represented 19.3% of the total and .5C recordings represented 16.2% of the total of all fractions since 1972. Together, .0C and .5C represented 35.5% of all minimum temperatures recorded since metrication.
