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.    To understand how to explore the data, see this page: https://storymaps.arcgis.com/stories/457e7a2bc73e40b089fac0e47c63a578    Please note, if viewing in ArcGIS Map Viewer, the map will default to ‘tas January’ values.    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_mon-30y_199101-202012.nc      Useful links  ·       Further information on HadUK-Grid  ·       Further information on understanding climate data within the Met Office Climate Data Portal
