Information Regarding SOLVE-II 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, ozone number density, aerosol depolarizations, and aerosol wavelength dependence. Logarithmic scales are used for the aerosol scattering ratio images to optimize display of PSC and sulfate layer features. Ozone mixing ratios and aerosol scattering ratios are calculated from DIAL measurements and atmospheric molecular densities from GSFC Assimilation Model GG1% 25x1 grid data interpolated to the DC-8 flight tracks. These molecular density curtain files were provided by GSFC codes 910.3 and 916.
