Coldest night of the season (1st percentile of daily minimum temperature)
The UKCP09 projections provide information on the 1st percentile of daily minimum temperature on a seasonal basis. This is assumed to represent the coldest night of each season.
UKCP09 projects changes in climate extremes that are based on the 1st percentile. Assuming each season is 100 days long, the 1st percentile roughly corresponds to 1 day per season. This variable can be thought of as the change in the temperature of the coldest night of each season, and changes are provided in probabilistic terms by UKCP09 over land areas.

- A complete list of climate variables for which probabilistic projections are available is given in Table 1.1 of the UKCP09 Climate change projections report. Some additional information about temperature is given in Box 1.2.
- Information is also available on observed temperature. The Observed trends report provides details of recent trends in mean, maximum and minimum temperature, as well as days of air frost. The UKCP09 Extremes Atlas provides details about daily extremes, heatwaves and coldwaves.
