Brightness temperature difference
WebApparent magnitude (m) is a measure of the brightness of a star or other astronomical object observed from Earth.An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer.. The word magnitude in … WebRTTOV simulation of brightness temperature (BT) differences with SST skin difference. The color indicates different values of aerosol related SST skin differences. When we rotate (or transform) the data distribution with the coordinate axis, the first PC can be used to represent the aerosol free situation and the second PC of the remaining ...
