What is infrared radiation (IR)? Definition from TechTarget

WebNew band 1 (ultra-blue) is useful for coastal and aerosol studies. New band 9 is useful for cirrus cloud detection. The resolution for Band 8 (panchromatic) is 15 meters. Thermal … WebOn the horizontal axis we see IR wavelengths expressed in terms of a unit called wavenumber (cm -1 ), which tells us how many waves fit into one centimeter. On the vertical axis we see ‘ % transmittance ’, which tells us how strongly light was absorbed at each frequency (100% transmittance means no absorption occurred at that frequency).
