radiance Maksud & Definisi

Contoh radiance

• Because bands 1 and 2 are relatively close on the electromagnetic spectrum, we can reasonably assume their aerosol radiances are the same.

• Over the land the retrieval of temperature from radiances is harder, because of the inhomogeneities in the surface.

• The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances.

• They measure radiances in various wavelength bands, from which temperature may be inferred.

• They measure radiances in various wavelength bands, which must then be mathematically inverted to obtain indirect inferences of temperature.

• As the satellites' orbits gradually decayed towards the earth the area from which they received radiances was reduced, introducing a false cooling trend.

• However, he treated it as an infinite collection of vectors, one per direction impinging on the point, with lengths proportional to their radiances.

• Weather satellites do not measure temperature directly but measure radiances in various wavelength bands.
