The National Centers for Environmental Information (NCEI) has introduced a new version of the global surface temperature NOAAGlobalTemp dataset. This update incorporates information from an artificial neural network (ANN) to enhance the accuracy of land and Arctic Ocean surface air temperature measurements, especially in areas with few observations. The ANN method demonstrates significant improvements over the previous method, particularly in the Southern Hemisphere and before the 1950s, offering a more precise picture of global temperature trends and anomalies.
