Tropospheric Emission Spectrometer (TES) CO2Red arrow indicates the change in radiance at 710 cm-1 due to change in CO2 at 10 km
• The 2 band between 680-725 cm-1 is sensitive mainly to CO2 in the upper troposphere and lower stratosphere
• The radiance in the spectral regions 970-990 and 1070-1110 cm-1 is sensitive to changes in CO2 in the middle and lower troposphere
