Ground-Based Solar UV Radiation Monitoring Technique Using Photocell

Ground Based Measurements of Solar UV Index in Tabriz

Introduction: Ultraviolet index (UVI) is a dimensionless scale, which describes the maximum intensity and biologic effects of UV during a specific time, on surface of the earth. The UVI is  an  international  standard measurement of  the  strength  of sunburn  producing ultraviolet radiation at a particular place and time. This index is an easy and understandable concept for pr...

Global monitoring of atmospheric ozone and solar UV radiation

The global monitoring network of ground-based ozone measurements consists mainly of Dobson and Brewer spectrophotometers. These instruments provide total ozone column amounts derived from measurements of direct solar UV radiation. Analysis of total ozone measurements from the global monitoring network shows a nearly linear downward trend from 1980 to mid 1990s. Data after mid 1990s indicate tha...

Solar ultraviolet radiation on the ground level of Isfahan

Introduction: Ultraviolet (UV) radiation affects human organs such as skin, eyes and immune system, as well as animals and plants. The main natural source of UV radiation is the Sun. To study the effects of solar UV radiation there is a need to quantify variations of solar energy received on the earth surface at different intervals. Materials and Methods: To measure UV radiation a broadband fib...

Ground-Based Monitoring of the Solar Wind Geoefficiency

Surface Uv Radiation Monitoring Based on Gome and Sciamachy

Solar UV radiation reaching the Earth’s surface is monitored by means of two quantities: the clear-sky UV index at local solar noon and the daily UV dose. Each quantity is determined on the basis of two action spectra, describing wavelength dependent biological effects of UV radiation, namely erythema (sunburn) and DNA-damage. The quantities are derived from total ozone column measurements by t...
