Angular distribution of Bremsstrahlung photons and of positrons for calculations of terrestrial gamma-ray flashes and positron beams
Bremsstrahlung pair production analytical integration of Bethe-Heitler equation distribution of scattering angles
2012/2/28
Within thunderstorms electrons can gain energies of up to hundred(s) of MeV. These electrons can create X-rays and gamma-rays as Bremsstrahlung when they collide with air molecules. Here we calculate ...
D/H variation in terrestrial lipids from Santa Barbara Basin over the past 1400 years: A preliminary assessment of paleoclimatic relevance
Santa Barbara Basin paleoclimatic relevance
2014/4/8
We analyzed D/H ratios of common terrestrial leaf wax lipids in a 1400 year sediment core from the Santa
Barbara Basin (SBB) to test whether they accurately record terrestrial climate in Southern Cal...
Terrestrial climate variability and seasonality changes in the Mediterranean region between 15 000 and 4000 years BP deduced from marine pollen records
Terrestrial climate marine pollen records seasonality changes
2009/12/3
Pollen-based climate reconstructions were performed on two high-resolution pollen marines cores from the Alboran and Aegean Seas in order to unravel the climatic variability in the coastal settings of...
Cold oceans enhance terrestrial new-particle formation in near-coastal forests
Cold oceans terrestrial new-particle formation near-coastal forests
2009/11/19
The world's forests produce atmospheric aerosol by emitting volatile organic compounds (VOC) which, after being oxidized in the atmosphere, readily condense on the omnipresent nanometer-sized nuclei a...
The CO2 inhibition of terrestrial isoprene emission significantly affects future ozone projections
CO2 inhibition terrestrial isoprene emission future ozone projections
2009/5/6
Simulations of future tropospheric composition often include substantial increases in biogenic isoprene emissions arising from the Arrhenius-like leaf emission response and warmer surface temperatures...

Predicting terrestrial 222Rn flux using gamma dose rate as a proxy
222Rn flux gamma dose rate proxy
2008/12/11
222Rn is commonly used as a natural tracer for validating climate models. To improve such models a better source term for 222Rn than currently used is necessary. The aim of this work is to establish a...
Process-based estimates of terrestrial ecosystem isoprene emissions: incorporating the effects of a direct CO2-isoprene interaction
terrestrial ecosystem isoprene emissions CO2-isoprene
2008/11/27
In recent years evidence has emerged that the amount of isoprene emitted from a leaf is affected by the CO2 growth environment. Many – though not all – laboratory experiments indicate that emissions i...
Why are estimates of global terrestrial isoprene emissions so similar（and why is this not so for monoterpenes）?

2008/11/14
Emissions of biogenic volatile organic compounds (BVOC) are a chief uncertainty in calculating the burdens of important atmospheric compounds like tropospheric ozone or secondary organic aerosol, refl...
Dynamics of the terrestrial biosphere, climate and atmospheric CO2 concentration during interglacials: a comparison between Eemian and Holocene
terrestrial biosphere climate atmospheric CO2 Eemian Holocene
2008/11/11
A complex earth system model (atmosphere and ocean general circulation models, ocean biogeochemistry and terrestrial biosphere) was used to perform transient simulations of two interglacial sections (...
Changes in Terrestrial Carbon Storage over China During the Holocene
Holocene carbon density carbon storage human activity China
2010/2/21
Using the paleo-vegetation maps previously reconstructed with pollen data and the modern carbon density data, the changes in terrestrial carbon storage in the Holocene in mainland China were analyzed....
