Answers to referee #2 comments received and published on 10 April 2008, on the manuscript: "Comparison of OMI ozone and UV irradiance data with ground-based measurements at two French sites." General comments : This well-written paper presents a comparison between OMI (TOMS-like and DOASlike) estimated total ozone content (TOC) and the value retrieved from two Jobin Yvon spectroradiometers at t...

Influenced by stratospheric total ozone column (TOC), cloud cover, aerosols, albedo, and other factors, levels of daily erythemal dose (Her) in a specific geographic region show significant variability time space. To investigate the degree randomness predictability Her series from ground-based observations Novi Sad, Serbia, during 2003–2012 period, we used set information measures: Kolmogorov c...

In Western countries, ultraviolet (UV)-induced skin cancer has been studied extensively regarding the high incidence of skin cancers in the white population; however, for people of color, cataracts are the main public health issue in relation to increased ambient ultraviolet radiation (UVR). To our knowledge, few studies have been conducted examining the relationship between cataracts and ambie...

Humans undertake their daily activities in a number of different postures. This paper aims to compare the anatomical distribution of the solar erythemal UV to human legs for standing and sitting postures. The exposure ratios to the legs (ratio of the UV exposure to a particular anatomical site compared to the ambient) have been measured with UV dosimeters for standing and sitting postures of a ...

Erythemal ultraviolet (UV)-radiation exposure to the right hand, mid-arm, shoulder, chin, nose and left and right sides of the face has been evaluated in a car from a large family class and a car from a small car class. In the small car, the site with highest exposure received 2.2 times more radiation than the site with the highest exposure in the larger car. In both cars, highest erythemal exp...

OBJECTIVES To compare narrowband UV-B (TL-01 lamp) phototherapy for psoriasis with individual patient starting doses based on minimal erythemal dose (MED) determination vs a standard fixed starting dose and to compare the efficacy of 70% of MED vs 50% of MED starting dose regimens. DESIGN Single-center, randomized, double-blind, clinical trial. SETTING Department of Dermatology, Ninewells H...

Vitamin D production in the skin by UV exposure is the most promising means of alleviating the worldwide burden of vitamin D deficiency. However, we demonstrate that Vitamin D production cannot be quantified by the current UV Index, which is based on the erythemal action spectrum. Large disagreement was observed when comparing (by computer simulation) the daily levels of erythemal UV and UV wei...

The results presented in this paper allow for the estimation of the monthly UV exposure of the human facial region at various locations across the earth. The technique allows a graphical representation of the UV exposures over the face. The erythemal UV exposures as well as the vitamin D exposures to the human facial region have been investigated. The results gained in this paper, for a clear s...

A method has been developed for determining the UV and erythemal exposures to the entire body. The difference between the ambient erythemal exposure and that to the body compared to the ambient exposure may be as high as 76%. The height, orientation, and overall height had a minimal effect on the exposure to the body with size, time of day and time of year having a significant effect. The diffu...
