University of Reading climatological statistics

Statistics from the University of Reading climatological record

These programs will allow you to extract observations from our long-running (since 1908) set of daily 0900 GMT climatological observations, and to cpmpare them day-by-day and year-by-year.

Some long-period statistics can also be generated.

This program computes statistics for the :: current 5-day period (period calculated since the start of the year); current 'third' of the month (typically 1st-10th, 11th-20th or 21st-31st); the current month and season of the year

Using this program allows you to compare recent and past observations - maybe to place a recent event into an historical context.

Such a comparison may be done using (a maybe unknown) value on a specific date (maybe today's date to compare a possible 'record' against past data), or by specifying a reference value in 'observation units' (eg. degC not K). and then looking to find higher or lower values from the past.

The comparison can be carried out against:

all the days in all the years,
all the days in one season over all years,
all the days in one month over all the years, or
the first, middle or final third of a specific month in all the years

Was this the first time Reading had had snow on Easter Monday? You can perform a statistical enquiry for a bank holiday period of your choice using this code.

Was it unusually cold/hot/wet/sunny/... yesterday? Check the weather for a single day of the year here.: This code generates a list of observations of one element for a specific day of the year since records began.

How does the warm/dryness/dull skies of the past n days compare to simialr spells in the past? Find out here.: This code may take a few seconds to run, depending upon the length of your 'spell'.
