Analysis on the causes of a continuous clear-sky gale event in winter in the Three Gorges Dam Area
暴雨灾害, 2022 A continuous clear-sky gale event (hereinafter referred to as "21·1" clear-sky gale in the dam area) occurs in the Three Gorges Dam Area in the middle January of 2021, which seriously affected the navigation safety of the Yangtze River near the dam area.

Detection of dimming/brightening in Italy from homogenized all-sky and clear-sky surface solar radiation records and underlying causes (1959–2013) [PDF]
Atmospheric Chemistry and Physics, 2016 A dataset of 54 daily Italian downward surface solar radiation (SSR) records has been set up collecting data for the 1959–2013 period. Special emphasis is given to the quality control and the homogenization of the records in order to ensure the ...

Uncertainties of parameterized surface downward clear-sky shortwave and all-sky longwave radiation. [PDF]
Atmospheric Chemistry and Physics, 2012 As many environmental models rely on simulating the energy balance at the Earth's surface based on parameterized radiative fluxes, knowledge of the inherent model uncertainties is important.

Polarization singularities in the clear sky [PDF]
New Journal of Physics, 2004 Ideas from singularity theory provide a simple account of the pattern of polarization directions in daylight. The singularities (two near the Sun and two near the anti-Sun) are points in the sky where the polarization line pattern has index +1/2 and the intensity of polarization is zero.

Long-term analysis of clear-sky new particle formation events and nonevents in Hyytiälä [PDF]
Atmospheric Chemistry and Physics, 2017 New particle formation (NPF) events have been observed all around the world and are known to be a major source of atmospheric aerosol particles. Here we combine 20 years of observations in a boreal forest at the SMEAR II station (Station for Measuring ...

Improving The Accuracy of the Empirical Clear Sky Solar Irradiance Models
Annals of West University of Timisoara: Physics, 2013 This paper is focused on improving the quality of nowcasting solar irradiance by enhancing the clear sky component of the model. A simple linear correction for the average atmospheric transmittance is proposed.

The impact of clear-sky biases of land surface temperature on monthly evapotranspiration estimation
International Journal of Applied Earth Observations and GeoinformationRemotely sensed land surface temperature (LST) is critical for retrieving evapotranspiration (ET). However, due to cloud contamination, LST is often limited to clear-sky conditions and the differences between clear-sky and all-sky LST will lead to clear ...
