While some locations experience many hours of sunshine yearly, others experience minimal average hours of sunshine. Sunshine duration is a commonly used climatological indicator. The duration of sunshine is measured for a given period, usually over the period of one year. Sunlight duration is expressed as an averaged value of sunlight hours over several years. Unlike insolation, which measures the total energy received from sunshine over a period, sunshine duration measurement is an indicator of general cloudiness of a place. Sunshine duration measurement helps in comparing the sunniness of a location in comparison to another. The measurement also helps compare sunniness of the same location on different seasons. Sunshine duration data comes in handy in characterizing the climate of sites such as health resorts and tourist destinations.
