Reduction of Spectral Radiance Reflectance During the Annular Solar Eclipse of 21 June 2020 Observed by EPIC

Frontiers in Remote Sensing, 2022
The annular solar eclipse on 21 June 2020 passed over desert areas (parts of Central and Eastern Africa, the southern Arabian Peninsula), partly cloudy regions (parts of South Asia and the Himalayas), and the mostly cloudy region in East Asia.

Structure and Dynamics of the 13/14 November 2012 Eclipse White-Light Corona [PDF]

, 2014
Continuing our series of observations of the motion and dynamics of the solar corona over the solar-activity cycle, we observed the corona from sites in Queensland, Australia, during the 13 (UT)/14 (local time) November 2012 total solar eclipse.

Acute Solar Retinopathy

Delhi Journal of Ophthalmology, 2013
Solar observation and eye damage is known for centuries. Unprotected eclipse viewing is the leading cause of solar retinopathy. Inspite of using commercially available certified solar filters, use of binoculars, exposed photographic film and X-ray film ...

An empirical study of near-surface air temperature time lags and delay function during the longest total solar eclipse of the 21st century at Tianhuangping (Zhejiang), China, under cloudy conditions

Meteorologische Zeitschrift, 2022
Among the different ways that the solar heating of the Earth's surface can be interrupted, the most impressive is by a solar eclipse. While the solar radiation drops rapidly, the near-surface air temperature responds more gradually, typically reaching a ...

Homogenizing Estimates of Heritability Among SOLAR-Eclipse, OpenMx, APACE, and FPHI Software Packages in Neuroimaging Data. [PDF]

Front Neuroinform, 2019
Imaging genetic analyses use heritability calculations to measure the fraction of phenotypic variance attributable to additive genetic factors. We tested the agreement between heritability estimates provided by four methods that are used for heritability

Restoring the top-of-atmosphere reflectance during solar eclipses: a proof of concept with the UV absorbing aerosol index measured by TROPOMI [PDF]

Atmospheric Chemistry and Physics, 2021
During a solar eclipse the solar irradiance reaching the top of the atmosphere (TOA) is reduced in the Moon shadow. The solar irradiance is commonly measured by Earth observation satellites before the start of the solar eclipse and is not corrected for ...

The Great Reduction of Equatorial Electrojet During the Solar Eclipse on 14 December 2020

Space Weather, 2022
The solar eclipse has a great influence on the variability of the ionosphere because of the obscuration of solar radiation. Using the equatorial electrojet (EEJ) and plasma measurements from Swarm, zonal winds from the Michelson Interferometer for Global
