Micro urban heat islands
Finds the few small hotspots that overheat whole districts, so one tree or one water basin can cool a neighbourhood.
Heat waves are getting longer and hotter, but urban climate analyses are elaborate and expensive. That is why most cities commission them only every five years, and why the results are too coarse to say where exactly a measure should go.
MUHID is affordable, fast and precise. It identifies the hottest places of a city at 10 × 10 metres from satellite data. A micro forest or a small water surface on one of these small hotspots can lower the temperature of the whole district. Minimal intervention, maximum effect.
Three steps from satellite image to cooler district.
Usual climate analyses are imprecise, expensive and quickly outdated. MUHID is precise, affordable and available any time, for any city in the world. And it matters most where summers are hottest.
Not a district average, but the exact spot. Fine enough that a single tree, a new surface or a small water basin becomes a meaningful measure.
Satellites pass every few days. MUHID updates weekly and compares across seasons and years, so measures can be checked instead of assumed.
MUHID uses the surface temperature the satellite actually measured, not a model of buildings and wind flow.
No simulation, no field survey, no sensors. MUHID is simple to use, and it scales to any city, anywhere.
