A severe heatwave is ongoing in Europe. Temperature records broken in France, Switzerland, Germany and Spain.
On 11 July 2023, the Land Surface Temperature (LST) in some areas of Extremadura (Spain) exceeded 60°C, as highlighted in this data visualisation derived from measurements from the Copernicus Sentinel-3 Sea and Land Surface Temperature Radiometer (SLSTR) instrument. The ongoing heatwave in Spain this week is resulting in a total of 13 autonomous communities, being at extreme risk (red alert), significant risk (orange alert), and risk (yellow alert) due to maximum temperatures that, in some cases, will exceed 40°C and reach a maximum of 43°C.
For reference, “in areas where vegetation is dense, the land surface temperature never rises above 35°C. The hottest land surface temperatures on Earth are in plant-free desert landscapes.”
Yeah, it’s confusing and unhelpful. People should standardize on reporting air temperature unless there’s a very specific and compelling reason not to.
Yep. Unless you’re trying to cook eggs on the ground, then you can start letting people know when it finally gets hot enough to do that.
