The solar eclipse: a natural meteorological experiment

A solar eclipse provides a well-characterized reduction in solar radiation, of calculable amount and duration. This captivating natural astronomical phenomenon is ideally suited to science outreach activities, but the predictability of the change in solar radiation also provides unusual conditions for assessing the atmospheric response to a known stimulus. Modern automatic observing networks us...

Performance of the meteorological radiation model during the solar eclipse

Various solar broadband models have been developed in the last half of the 20th century. The driving demand has been the estimation of available solar energy at different locations on earth for various applications. The motivation for such developments, though, has been the ample lack of solar radiation measurements at global scale. Therefore, the main goal of such codes is to generate artifici...

An eclipse experiment to study the solar chromosphere and spicules

An experiment is proposed to measure a critical part of the chromospheric flash spectrum during the eclipse which will occur November 13, 2012. The idea is to obtain rapid (30 Hz), high signal-to-noise spectrographic data at at least one chromospheric line, the calcium H line being the most desirable, at a spectral resolution of 15,000 or higher. A small telescope with a small exit pupil can be...

The effect of the total solar eclipse of 29 March 2006 on meteorological variables in Greece

This paper examines the effect of the total solar eclipse of 29 March 2006 on meteorological variables across Greece. Integrated micrometeorological measurements were conducted at Kastelorizo, a small island within the path of totality, and other sites within the Greek domain, with various degrees of solar obscuration. The observa5 tions showed a dramatic reduction in the incoming global radiat...
