Land surface temperature (LST) on Iceland has been retrieved by means of remote sensing for the period 2001-2023.  The trend in the data shows substantial geographical variability on different scales and is partly very different from the general upward trend in the 2 m temperatures.  There are areas with strong negative trend and other areas with strong positive trend.  The variability may be attributed to changes in snow cover and vegetation.  Impact of volcanic eruptions and retreat of glaciers are also detected.  The results suggest that using data decades back in time to train forecasting models may lead to systematic errors in surface temperature forecasts.
