Calculation of UV resources

Latitude, degrees:

Latitude should be expressed in decimal degrees.

Longitude, degrees:

Longitude should be expressed in decimal degrees.Negative values indicate the longitudes in the Western hemisphere.

Altitude, km:

Enter surface UV albedo
NOTE: If you do not know exactly the UV albedo at your point, you can use approximate UV albedo according to the type of surface and surroundings: ground (grass) - 2%; trees and snow - 40%; bare snow within 1 km - 70%

Use climatological value of surface UV albedo

Albedo, %:

In range 0...90%

Enter total ozone content, DU

Use climatological value of total ozone content, DU

Total ozone content, DU:

In range 150...490 DU

Enter aerosol optical thikness at 380 nm

Use climatological value of aerosol optical thikness at 380 nm

Aerosol optical thikness at 380 nm:

In range 0...0.99

Cloudiness:

Clear sky conditions

Average sky conditions

Enter cloud modification factor in UV spectral range

Cloud modification factor:

In range 0...1

Month:

Day:

Skin type:

Open body fraction:

NOTE: Full body - 1; face and neck - 0.09; arms - 0.18; legs - 0.36; palm and fingers - 0.01
