¹⁰Be in late deglacial climate simulated by ECHAM5-HAM – Part 2: Isolating the solar signal from ¹⁰Be deposition [PDF]

Climate of the Past, 2014
This study investigates the effect of deglacial climate on the deposition of the solar proxy 10Be globally, and at two specific locations, the GRIP site at Summit, Central Greenland, and the Law Dome site in coastal Antarctica.

Cloud, precipitation and radiation responses to large perturbations in global dimethyl sulfide [PDF]

Atmospheric Chemistry and Physics, 2018
Natural aerosol emission represents one of the largest uncertainties in our understanding of the radiation budget. Sulfur emitted by marine organisms, as dimethyl sulfide (DMS), constitutes one-fifth of the global sulfur budget and yet the ...

Evaluation of modelled LOTOS-EUROS with observational based PM10 source attribution

Atmospheric Environment: X, 2022
Due to its serious health impact particulate matter is one of the air pollutants subject to abatement policies. Information on the main sources responsible for high concentrations of pollutants is therefore crucial to enable effective policy measures. In

Diel quenching of Southern Ocean phytoplankton fluorescence is related to iron limitation [PDF]

Biogeosciences, 2020
Evaluation of photosynthetic competency in time and space is critical for better estimates and models of oceanic primary productivity. This is especially true for areas where the lack of iron (Fe) limits phytoplankton productivity, such as the Southern ...

Assessment of Carbon Stock at Tree Level Using Terrestrial Laser Scanning Vs. Traditional Methods in Tropical Forest, India

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Accurate assessment of carbon stock of trees is essential to model carbon dynamics in the forest ecosystem. Estimation of carbon stock at regional level involves successive quantitative modeling at various scales.
