Using an infrared thermometer to measure the difference in temperature between mown paths and the unmown areas in my garden
@NigelWitham That's amazing. Here's our lawn managed by @JWandCoLangleys , mowed every week which is why it looks like this. Where can I get that thermometer from?
@NigelWitham I live in one of the coolest places in Thailand. The reason it's so cool is because the vast stretches of forest here. This proves that point at a smaller scale. Now imagine what it's like when 90% of forests and wetlands are destroyed.
@NigelWitham Our grass v neighbour’s plastic @Shitlawns
@NigelWitham Is that a little yellow rattle I spy there! 🙂👍
@NigelWitham Do you know the reason for such a big difference? Which bit are you measuring exactly? Presume surface temp is similar but towards the ground, where the long grass offers shade, it is cooler?
@NigelWitham The shade in the lower temp reading helps too, huh?
@NigelWitham Those infra red thermometers are set for specific reflective surfaces, you won't get a reading anywhere near accurate with them.
@NigelWitham I think there is a good chance you are just measuring the difference in reflected sunlight. My guess is that a contact thermometer will give you a quite different result as would repeating the measurements in full shade.
@NigelWitham @flygirlNHM We have a single strip mown as a path to the shed but it never occurred to me that there was such a temperature difference!
