AERI Microwindow Regions

 
A number of regions exist between atmospheric absorption lines which can be observed by the high spectral resolution of the AERI, see Table 6. These `microwindows' comprise the least absorbing regions within the spectral bandpass of the instrument.

Figures 34 through 36 note these regions and illustrate the change in AERI measured radiance due to the presence of cirrus (upper curve) relative to a clear atmosphere (lower curve). Aerosol loading (e.g., wind blown dust, increased humidity, industrial effluence) will also yield higher microwindow emission.
