In practice, any temperature sensor mounted at a height of one and a half times the height of roughness objects (buildings, trees etc) is expected to be largely unaffected by those objects, so putting a tall pole above your house is deemed okay. | In practice, any temperature sensor mounted at a height of one and a half times the height of roughness objects (buildings, trees etc) is expected to be largely unaffected by those objects, so putting a tall pole above your house is deemed okay. | ||
A more advanced model considers the density of the roughness, and for lots of tightly packed buildings (or trees), uses a bigger clearance (height or horizontal separation). (See Royal Meteorological Society website in UK, or the equivalent of a Meteorological Bureau for your country). | A more advanced model considers the density of the roughness, and for lots of tightly packed buildings (or trees), uses a bigger clearance (height or horizontal separation).
