Influence of cloudy and clear-sky partitions, aerosols, and geometry on the recent variability in surface solar irradiance components in northern France [PDF]

open access: yesAtmospheric Chemistry and Physics
Surface solar irradiance (SSI) is a fundamental parameter whose components (direct and diffuse) and variabilities are highly influenced by changes in atmospheric content and scene parameters.

Retrieval of Aerosol Microphysical Properties from Multi-Wavelength Mie–Raman Lidar Using Maximum Likelihood Estimation: Algorithm, Performance, and Application

open access: yesRemote Sensing, 2022
Lidar plays an essential role in monitoring the vertical variation of atmospheric aerosols. However, due to the limited information that lidar measurements provide, ill-posedness still remains a big challenge in quantitative lidar remote sensing. In this

Mobile Observations by Lidar, Sun Photometer and in Situ in North China Plain [PDF]

open access: yesEPJ Web of Conferences, 2020
A mobile laboratory integrating lidar, sun photometer and in situ instruments has been deployed to observe the aerosol spatial variability in North China Plain in May 2017. Results from the campaign are presented.

Synergy of active and passive airborne observations for heating rate calculation during the AEROCLO-sA field campaign in Namibia [PDF]

open access: yesAtmospheric Measurement Techniques
Aerosols have important effects on both local and global climate, as well as on clouds and precipitations. We present original results derived from the airborne observations acquired from the AErosol RadiatiOn and CLOud in Southern Africa (AEROCLO-sA ...

Variability in lidar-derived particle properties over West Africa due to changes in absorption: towards an understanding [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Measurements performed in western Africa (Senegal) during the SHADOW field campaign are analyzed to show that spectral dependence of the imaginary part of the complex refractive index (CRI) of dust can be revealed by lidar-measured particle parameters ...

Invited - Lightwave-Controlled Relativistic Plasma Mirrors At kHz Repetition Rate [PDF]

open access: yesEPJ Web of Conferences
Plasma mirrors driven at kHz-repetition-rate with waveform-controlled relativistic-intensity near-single-cycle laser pulses produce extreme ultraviolet spectral continua supporting isolated attosecond pulses with diffraction limited beam quality. A newly

Satellite inference of water vapour and above-cloud aerosol combined effect on radiative budget and cloud-top processes in the southeastern Atlantic Ocean [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Aerosols have a direct effect on the Earth's radiative budget and can also affect cloud development and lifetime, and the aerosols above clouds (AAC) are particularly associated with high uncertainties in global climate models.
