Observed data refers to information that has been directly measured. In climatology, this means measurements of climate variables such as temperature and precipitation.
Observed climate data in the UK is obtained from a network of synoptic and weather stations. This data is commonly processed to convert irregularly spaced point observations to a regular grid. Observed climate data can be used both to explore past climate trends and to construct and validate climate models.
