Airborne dust distributions over the Tibetan Plateau and surrounding areas derived from the first year of CALIPSO lidar observations [PDF]

Atmospheric Chemistry and Physics, 2008
Using an analysis of the first full year of CALIPSO lidar measurements, this paper derives unprecedented, altitude-resolved seasonal distributions of desert dust transported over the Tibetan Plateau (TP) and the surrounding areas.

Evaluation of Aeolus feature mask and particle extinction coefficient profile products using CALIPSO data [PDF]

Atmospheric Measurement Techniques
The Atmospheric LAser Doppler INstrument (ALADIN) on board Aeolus was the first high-spectral-resolution lidar (HSRL) in space. It was launched in 2018 and re-entered in 2023. The FeatureMask (A-FM) and extinction profile algorithms (A-PRO) developed for

Monte Carlo Simulation of 3D Cloud Radiance Distributions Affected by Ground‐Based Lighting

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Satellite observations of artificial light sources at night are increasing. Clouds, as the most important radiative modulators in the Earth‐atmosphere system, significantly influence the observed values and spatial distribution of the artificial light coming from the ground.

Quantifying black carbon deposition over the Greenland ice sheet from forest fires in Canada [PDF]

, 2017
Black carbon (BC) concentrations observed in 22 snowpits sampled in the northwest sector of the Greenland ice sheet in April 2014 have allowed us to identify a strong and widespread BC aerosol deposition event, which was dated to have accumulated in the ...

Hemispheric Synoptic Patterns Control Rainfall and Long‐Range Aerosol Transport in the Amazon

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The transatlantic transport of dust and smoke aerosols from Africa to South America is a large‐scale, year‐round process that affects atmospheric and nutrient cycling in the Amazon rainforest. We analyze daily variations in black carbon at the Amazon Tall Tower Observatory (ATTO) to investigate how Atlantic synoptic‐scale meteorology ...

Combined CloudSat-CALIPSO-MODIS retrievals of the properties of ice clouds [PDF]

, 2010
In this paper, data from spaceborne radar, lidar and infrared radiometers on the “A-Train” of satellites are combined in a variational algorithm to retrieve ice cloud properties. The method allows a seamless retrieval between regions where both radar and

Spaceborne lidar measurement of global cloud properties through machine learning

Frontiers in Remote Sensing
With a large footprint size, multiple scattering measurements of clouds from spaceborne lidar provide useful information about cloud physical properties, such as cloud optical depths and cloud droplet size, both during daytime and nighttime.

Assessment of Aerosol Distributions from GEOS-5 Using the CALIPSO Feature Mask [PDF]

, 2010
A-train sensors such as MODIS, MISR, and CALIPSO are used to determine aerosol properties, and in the process a means of estimating aerosol type (e.g. smoke vs. dust).

Vertical Profiles of Aerosol Optical Properties Over Central Illinois and Comparison with Surface and Satellite Measurements [PDF]

, 2012
Between June 2006 and September 2009, an instrumented light aircraft measured over 400 vertical profiles of aerosol and trace gas properties over eastern and central Illinois. The primary objectives of this program were to (1) measure the in situ aerosol
