What does the data show? This data shows the monthly averages of maximum surface temperature (°C) for 1981-2010 from CRU TS (v. 4.06) dataset. It is provided on the WGS84 grid which measures approximately 60km x 60km (latitude x longitude) at the equator. This is the same as the 60km grid used by UKCP18 global datasets.   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 'tmax' (temperature minimum) and the month. E.g. ‘tmax March’ is the average of the daily maximum temperatures in March throughout 1981-2010.   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 ‘tmax January’ values.   Data source CRU TS v. 4.06 - (downloaded 12/07/22)   Useful links Further information on CRU TS Further information on understanding climate data within the Met Office Climate Data Portal
