Solar Radiation at Total Solar Eclipse, 29-March 2006, at Tobruq

Abstract

<b>Problem statement:</b> Measurement of the different components of solar radiation and&#13; fractions of these components for the global (horizontal and tracker), direct (white and three colors,&#13; yellow, red and infrared) and diffuse solar radiation during the solar eclipse, 29 March 2006 at Tobruq,&#13; Libya (Lat. 32.08°N and Long. 23.98°E). The time interval of solar eclipse was 2 h: 40 m and the&#13; maximum magnitude of eclipse at this region was 0.995. <b>Conclusion: </b>The results showed that the&#13; maximum percent of color in the total direct solar radiation during the true eclipse from the first&#13; contact to the end contact was in the infrared, where the percent were in the green (11.74%), yellow&#13; (15.69%), red (14.88%) and infrared (57.68%)

Impact of the Eclipsed Sun on Terrestrial Atmospheric Parameters in Desert Locations: A Comprehensive Overview and Two Events Case Study in Saudi Arabia

“…Measurements of the atmospheric response during the annular solar eclipse of 3 October 2005 have been reported in these regions by [159] in Egypt, and by Anbar (2006) [118] in Saudi Arabia. Also during the total solar eclipse of 29 March 2006, measurements made by Möllman and Vollmer (2006) [160], Uddin et al (2007) [123], Pintér et al (2008), Pleijel (2008) [20] and Stoev et al (2008Stoev et al ( , 2012 [122,161] in Turkey, by Nawar et al (2007) [162] in Egypt, by [119] in Libya and, by Nymphas et al (2009) [163] in Nigeria, were reported. Recently the solar eclipse of 1st September 2016 was observed by Ojobo et al (2017) [146] in Nigeria, and the annular solar eclipse of 26 December 2019 was observed by Nelli et al (2020a) [7] in the United Arab Emirates (U.A.E.)…”

“…Next is the 29 March mid-day almost total eclipse (99.98%) of 2006 at Tubruq, Lybia (third line in Table 6), near the Mediterranean coast with a background considered to be a desert [119]. The impact on temperature, RH, and VP were also evident but not so large.…”

“…Table 6 contains useful information on temperature, RH, and VP response to solar eclipses (total, annular, and partial) in different desert or semi-arid environments located in the southern U.S.A., northern Africa, and in the Near East, within a region comprised between (20 • 26 ′ -36 • 22 ′ ) N and (106 • 20 ′ -40 • 00 ′ ) W-E (see map of Figure 14), to be intercompared. This information has directly been taken or estimated from the works of Jaubert (1906) [8], Klein and Robinson (1955) [9], Anderson and Keefer (1975) [10], Eaton et al (1997) [75], Hassan et al (1999) [12], and Hassan and Rahoma (2010) [119].

Changes in meteorological parameters during the total solar eclipse of 2 July 2019 in La Serena, Chile

“…Also, Founda et al [2007] investigated solar radiation variations during the same eclipse in Greece. Later, Hassan and Rahoma [2010] recorded global, direct, and diffuse solar radiation during this event in Tobruq, Libya.…”
