INTEX-NA UV DIAL IMAGES

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 modeled molecular densities.

Resolution of UV-DIAL Image data are:

VERTICAL RESOLUTION:


Vertical averaging interval
Ozone          below a/c altitude: 300 meters
               above a/c altitude: 600 meters 
ALL others                         300 meters 

Vertical display interval for averaged data
All                      60 meters

HORIZONTAL RESOLUTION:


Horizontal averaging interval
Aerosol                   1  minute, or approximately  14.0 km.
Ozone                     3 minutes, or approximately  42.0 km.

Horizontal display interval for averaged data.
All                       4 seconds or approximately 0.934 km.

      Times on the images are Universal Time (UT).
