What does the data show?  Annual averages of daily maximum surface temperature (°C) for the 1991-2020 period from HadUK gridded data (v1.1.0.0), provided on a 12km British National Grid (BNG).     Limitations of the data  We 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 the average over the 1991-2020 period. It is named 'tmax' (temperature maximum).    To understand how to explore the data, see this page: https://climatedataportal.metoffice.gov.uk/pages/user-guide  Data source:?  ·       Version: HadUK-Grid v1.1.0.0 (downloaded 26/08/2022)  ·       Source: https://catalogue.ceda.ac.uk/uuid/652cea3b8b4446f7bff73be0ce99ba0f  ·       Filename: tasmax_hadukgrid_uk_12km_ann-30y_199101-202012.nc      Useful links  ·       Further information on HadUK-Grid  ·       Further information on understanding climate data within the Met Office Climate Data Portal
