What does the data show?  The data shows the annual average of surface temperature (°C) for the 1991-2020 period from HadUK gridded data. It is 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 'tas' (temperature at surface).    To understand how to explore the data, see this page: https://storymaps.arcgis.com/stories/457e7a2bc73e40b089fac0e47c63a578    Data source:   ·       Version: HadUK-Grid v1.1.0.0 (downloaded 21/06/2022)  ·       Source: https://catalogue.ceda.ac.uk/uuid/652cea3b8b4446f7bff73be0ce99ba0f  ·       Filename: tas_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
