Concept information
Preferred term
IRIS
Definition
- The Infrared Interferometer Spectrometer and Radiometer (IRIS) on the Nimbus spacecraft actually acts as three separate instruments. First, it is a very sophisticated thermometer. It can determine the distribution of heat energy a body is emitting, allowing scientists to determine the temperature of that body or substance. Second, the IRIS is a device that can determine when certain types of elements or compounds are present in an atmosphere or on a surface. Third, it uses a separate radiometer to measure the total amount of sunlight reflected by a body at ultraviolet, visible, and infrared frequencies. [Source: NASA] (en)
