Information Regarding SOLVE 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 for ozone mixing ratio, ozone number density, aerosol depolarizations and aerosol wavelength dependence. Several linear and logarithmic scales are used for the aerosol scattering ratio images to optimize display of PSC and sulfate layer features. Images of depolarization at 1064 nm and 603 nm and wavelength dependence of the 1064 to 603 scattering ratios are only shown when PSC's are present. Ozone mixing ratios and aerosol scattering ratios are calculated from DIAL measurements and atmospheric molecular densities from JPL Microwave Temperature Profiler (MTP) atmospheric densities preliminary data. Horizontal running average interval of ozone measurements is 5 minutes up to 19 km and 10 minutes above 19km (70 km and 140 km, respectively at DC-8 speed of 14 km/min). Ozone data are truncated at upper altitudes when standard error exceeds 10% of the average.
