Comments: The absorption cross sections of surface-adsorbed HNO3 in the 290-330 nm region has been measured with Brewster 
angle cavity ring-down spectroscopy. The 295 K absorption cross sections for HNO3 adsorbed on fused silica surfaces are at least 
two orders of magnitude larger than those in the gas phase in the wavelength region studied.
