Collisions with the Earth: the Moon's contribution
(Elsevier B.V., 2004-01-01)
In the present work is analyzed the contribution of the Moon on the collisional process of the Earth with asteroids (NEOs). The dynamical system adopted is the restricted four-body problem Sun-Earth-Moon-particle. Using a ...
EVALUATION OF ACCELERATION OF ATMOSPHERIC ELECTRONS DUE TO HIGH POWER HF TRANSMISSION TO EARTH IONOSPHERE
(Universidad de TarapacáFacultad de Ingeniería, 2006)
Catastrophic bolide impacts on the Earth: Some estimates
(American Association of Physics Teachers, 2006-09)
We analyze the impact of large high velocity bodies on the surface of the Earth and obtain estimates of the size of the crater. We show that the atmosphere does not stop large bolides and their mass loss and heating during ...
Short-period variation of cosmic-ray intensity and ozone density observed in the stratosphere
(1993-01-01)
The energy deposition by slowing-down of energetic ionizing particles in the atmosphere enhances the production of constituent concentration which perturbs and eventually destroys the ozone (OZ) layer. Near the Brazilian ...

Implementation of methane cycling for deep-time global warming simulations with the DCESS Earth system model (version 1.2)
(Copernicus Publications, 2017)
Geological records reveal a number of ancient, large and rapid negative excursions of the carbon-13 isotope. Such excursions can only be explained by massive injections of depleted carbon to the Earth system over a short ...

Fog deposition to a Tillandsia carpet in the Atacama Desert
(COPERNICUS GESELLSCHAFT MBH, 2009)
In the Atacama Desert, one of the driest places on earth, fog deposition plays an important role for the water balance and for the survival of vulnerable ecosystems. The eddy covariance method, previously applied for the ...
