What does the data show? 

The data shows monthly averages of surface temperature (°C) for 1991-2020 from HadUK gridded data. It is provided on a 12km British National Grid (BNG). 

Limitations of the dataWe recommend the use of multiple grid cells or an average of grid cells around a point of interest to help users get a sense of the variability in the area. This will provide a more robust set of values for informing decisions based on the data.What are the naming conventions and how do I explore the data? 

This data contains a field for each month’s average over the period. They are named 'tas' (temperature at surface) and the month. E.g. 'tas March' is the average surface temperature for March in the period 1991-2020.
