All-sky direct aerosol radiative effects estimated from integrated A-Train satellite measurements [PDF]

Atmospheric Chemistry and Physics
The improvement of satellite-derived calculations of direct aerosol radiative effects (DARE) is essential for reducing the uncertainty in the impact of aerosol on solar radiation.

Polar observations of electron density distribution in the Earth’s magnetosphere. 1. Statistical results [PDF]

Annales Geophysicae, 2002
Forty-five months of continuous spacecraft potential measurements from the Polar satellite are used to study the average electron density in the magnetosphere and its dependence on geomagnetic activity and season.

Improved satellite retrievals of NO₂ and SO₂ over the Canadian oil sands and comparisons with surface measurements [PDF]

Atmospheric Chemistry and Physics, 2014
Satellite remote sensing is increasingly being used to monitor air quality over localized sources such as the Canadian oil sands. Following an initial study, significantly low biases have been identified in current NO2 and SO2 retrieval products from the

EUREC⁴A observations from the SAFIRE ATR42 aircraft [PDF]

Earth System Science Data, 2022
As part of the EUREC4A (Elucidating the role of cloud–circulation coupling in climate) field campaign, which took place in January and February 2020 over the western tropical Atlantic near Barbados, the French SAFIRE ATR42 research aircraft (ATR ...

Cirrus cloud optical and microphysical property retrievals from eMAS during SEAC⁴RS using bi-spectral reflectance measurements within the 1.88  µm water vapor absorption band [PDF]

Atmospheric Measurement Techniques, 2016
Previous bi-spectral imager retrievals of cloud optical thickness (COT) and effective particle radius (CER) based on the Nakajima and King (1990) approach, such as those of the operational MODIS cloud optical property retrieval product (MOD06), have ...

Effect of water vapor on the determination of aerosol direct radiative effect based on the AERONET fluxes [PDF]

Atmospheric Chemistry and Physics, 2014
The aerosol direct radiative effect (ADRE) is defined as the change in the solar radiation flux, F, due to aerosol scattering and absorption. The difficulty in determining ADRE stems mainly from the need to estimate F without aerosols, F0, with either ...

Evaluating the Significance of the Contrail Effect on Diurnal Temperature Range Using the Eyjafjallajökull Eruption‐Related Flight Disruption

Geophysical Research Letters, 2018
Meteorological data collected during the post‐9/11 flight grounding in the United States suggested that the removal of contrails increased diurnal temperature range (DTR), but subsequent research has contested this result.

Influence assessment of physical and geographical conditions for flat terrain on flight visibility [PDF]

Известия Саратовского университета. Новая серия: Серия Науки о Земле
Introduction. A flight visibility model is presented that takes into account the nature of the underlying surface, the height of the flat terrain, and the dynamics of the aircraft flight due to changes in altitude and ground speed during aerial work ...
