Differences in temperature on open and vegetated soils

Yesterday, at gentle 24 ° C air temperature, I measured the soil surface temperatures (for the first time). On the areas with open soil in the corn field of our neighbour: over 50°C. In the clover grass on our side: 26°C.

It’s amazing how the soil heats up (and was another 6°C warmer than the (rough) road next to it). Problematic not only for the soil life, soil water and for many crops. Also not good for the climate, because of warming of air temperature in this area, increased heat radiation, on larger areas potential development of high pressure areas, possible reduction of precipitation, … For more see my UNEP article and presentation, and the Climate Landscapes conference.
