Abstract
Our study examines a 5-year data set of erythemal ultraviolet radiation (EUV) collected at four locations in
Thailand: Chiang Mai (18.78 °N, 98.98 °E), Ubon Ratchathani (15.25 °N, 104.87 °E), Nakhon Pathom (13.82 °N, 100.04 °E)
and Songkhla (7.20 °N, 100.60 °E). Seasonal changes are strongly influenced by the wet and dry season in this tropical
environment, with maximum daily and noontime irradiances being reached in April or May, prior to the onset of the wet
season. Transmission by aerosols, estimated by comparison of cloudless measured irradiance with a cloudless sky model,
ranges from 51% at Chiang Mai to 83% at Songkhla during the dry season. By contrast, higher transmissions characterise
the wet season when values around 90% are reached. Cloud cover further depletes the EUV irradiance and wet season
transmissions range from 68% at Chiang Mai to 79% at Songkhla. Three of the four stations record increases in EUV
irradiance over the study period.
