High Quality weather station audit

Derby Aero 3032 raw temperature audit

Station opened 17 April 1972 audit to 31 December 2011

(See also Derby Post Office 3007)

Derby Aero 3032 maximum temperature audit

At Derby Aero 3032 from 17 April 1972 to September 1972, whole .0 Fahrenheit degrees represented 16.8% of all maximum temperatures recorded.

The short five month time span between station opening and August 31 1972 makes a comparison of .0C and .5C recordings meaningless.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 11.1% of the total and .5C recordings represented 10.4% of the total of all fractions since 1972. Together, .0C and .5C represented 21.6% of all maximum temperatures recorded since metrication.

Derby Aero 3032 minimum temperature audit

At Derby Aero 3032 from 18 April 1972 to September 1972, whole .0 Fahrenheit degrees represented 14% of all minimum temperatures recorded.

The short five month time span between station opening and August 31 1972 makes a comparison of .0C and .5C recordings meaningless.

From 1972-2011, minimum temperature recordings of .0 Celsius degrees represented 17.2% of the total and .5C recordings represented 11% of the total of all fractions since 1972. Together, .0C and .5C represented 28.2% of all minimum temperatures recorded since metrication.
