The data represet the relative exposure-damage to the 
DNA molecule from solar radiation.

Regions of pink represent the highest rates of exposure 
that occur over Mexico and parts of the Southwestern US.

Hawaii, on the far left, is in a band of lesser exposure, 
yellow, showing the effect of altitude on UV exposure.
Hawaii is assumed to be at sea level for this map.  
Of course, exposure on Mauna Loa would be increased compared 
to the beach area.

The data are truncated at 65 North so that most of Alaska 
is not covered.  However, the southern portions of Alaska
are similar to Canada and have very low exposure rates to 
UV
