Effects of solar activity on noise in CALIOP profiles above the South Atlantic Anomaly [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
We show that nighttime dark noise measurements from the spaceborne lidar CALIOP contain valuable information about the evolution of upwelling high-energy radiation levels.

Reconciling aerosol light extinction measurements from spaceborne lidar observations and in situ measurements in the Arctic [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
In this study we investigate to what degree it is possible to reconcile continuously recorded particle light extinction coefficients derived from dry in situ measurements at Zeppelin station (78.92° N, 11.85° E; 475 m above sea level), Ny-Ålesund ...

Exploring the Scientific Utility of Combined Spaceborne Lidar and Lightning Observations of Thunderstorms

open access: yesEarth and Space Science, 2022
Approximately 8 months of colocated spaceborne lidar and lightning observations were analyzed in a pathfinder study to understand the advantages and challenges of using these combined observations to understand thunderstorms.

Optical properties of Central Asian aerosol relevant for spaceborne lidar applications and aerosol typing at 355 and 532 nm [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
For the first time, a dense data set of particle extinction-to-backscatter ratios (lidar ratios), linear depolarization ratios, and backscatter- and extinction-related Ångström exponents for a Central Asian site are presented.

Examining the Impact of Topography and Vegetation on Existing Forest Canopy Height Products from ICESat-2 ATLAS/GEDI Data

open access: yesRemote Sensing
Forest canopy height (FCH) is an important variable for estimating forest biomass and ecosystem carbon sequestration. Spaceborne LiDAR data have been used to create wall-to-wall FCH maps, such as the forest tree height map of China (FCHChina), Global ...

The ESA-EVE Polarization Lidar for Assessing the Aeolus Aerosol Product Perfomance [PDF]

open access: yesEPJ Web of Conferences, 2020
We present the EVE lidar concept, a combined linear/circular polarization system, tailored to evaluate the spaceborne ALADIN Doppler lidar system aerosol retrievals. EVE, currently under development, aims to provide the ESA-Aeolus mission with a flexible,

Assessment of CALIOP-Derived CCN Concentrations by In Situ Surface Measurements

open access: yesRemote Sensing, 2022
The satellite-based cloud condensation nuclei (CCN) proxies used to quantify the aerosol-cloud interactions (ACIs) are column integrated and do not guarantee the vertical co-location of aerosols and clouds.

Informing spatial conservation prioritization with species’ traits

open access: yesConservation Biology, EarlyView.
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.
