Method for determining current synthetic ultraviolet index for a specified location

A method of determining a current synthetic ultraviolet (UV) index value for a given location, comprising:

• determining a closest cloud cover condition and a closest total column ozone available to said given location;
• interpolating a cloud cover condition for said given location from said closest cloud cover condition;
• interpolating a total column ozone for said given location from said closest total column ozone;
• determining a clear sky UV radiation for said given location using said interpolated total column ozone for said given location;
• determining a cloud adjusted UV radiation using said interpolated cloud cover condition for said given location;
• and
• converting said cloud adjusted UV radiation to UV index units.

A system for providing a current synthetic UV index value for a specified location, said system comprising:

• a first interface for receiving a request for said current synthetic UV index value for said specified location;
• wherein said request comprises a geographical location of said specified location, and a date and a time of day of said request and wherein said specified location may not be equipped with UV instrumentation;
• a database storing data comprising a closest cloud cover condition to said specified location, and a closest total column ozone available to said specified location;
• a server having an algorithm for determining said current synthetic UV index value for said specified location using said geographical location of said specified location, said date and time of day of said request, said closest cloud cover condition to said specified location, said closest total column ozone available to said specified location, wherein said closest cloud cover condition to said specified location is interpolated to said specified location;
• and
• a second interface for transmitting said current synthetic UV index value for said specified location.
