Information Regarding PAVE UV DIAL Images

Major UV DIAL References and other Related Publications.

For full flight images, the horizontal display interval can vary depending on the length of the flight and for subsample images, the horizontal display interval is always constant. Vertical scales are consistent on all full flight and subsample images. Color scales do not change between images for ozone mixing ratio, aerosol scattering ratio, aerosol depolarization, and aerosol wavelength dependence. Logarithmic scales are used for the aerosol scattering ratio images to optimize display of aerosol features. Ozone mixing ratios and aerosol scattering ratios are calculated from the DIAL measurements and molecular densities from the GSFC Assimilation GG1%25x1 grid data interpolated to the DC8 flight curtain.

      
Vertical averaging interval
Ozone          below a/c altitude: 525 meters
               above a/c altitude: 750 meters, and 1500 meters for the highest 2 km of data
