The spatial distribution of Erythemal Ultraviolet Dose Rate (EUV) at noon in mW/m2 observations derived from the
Ozone Monitoring Instrument (OMI) are presented over Egypt covering the geographical domain (22.5�°â��31.5�°N, 25.5�°â��
35.5�°E) during twelve year from 2005 to 2015. In the frame of the variability, Egypt was considered as an average area (one
pixel); the box-whisker plots were created for average monthly and annual values of EUV. The monthly mean of EUV values
are lower in the winter months (December to February) 116.17�±2.30 mW/m2 compared to those in the summer months (June
to August) 282.36�±2.87 mW/m2. The annual mean of EUV values are lower in 2015 (204.15�±60.41 mW/m2) and higher in
2013 (213.13�±60.34 mW/m2). For the purpose of mapping contour, with a spatial resolution of 1�°��1�°, 104 pixels, the results
illustrated by monthly, seasonally and all period contour maps indicate high similarity of EUV in all years. Finally comparisons
of ground-based measurement of Erythemal Ultraviolet Dose Rate (EUVpyr) using a UVB-1 pyranometer with Ultraviolet
Dose Rate (EUVomi) from OMI satellite data have been examined in Qena, Upper Egypt (26�° 16` N, 32�° 75` E, 96 m asl) at
noontime in mW/m2. The examination revealed an overestimation of EUVomi, on deviation average by 13.37�±11%, within the
period of study from 2006 to 2015 (except 2011-2012).
