Volcanic activity changes Earth mantle were key rise atmospheric oxygen
2020/6/12
Oxygen first accumulated in the Earth's atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photos...
A method to represent ozone response to large changes in precursor emissions using high-order sensitivity analysis in photochemical models
represent ozone response precursor emissions high-order sensitivity analysis photochemical models
2014/12/12
Photochemical grid models (PGMs) are used to simulate tropospheric ozone and quantify its response to emission changes. PGMs are often applied for annual simulations to provide both maximum concentrat...
Attribution of ozone changes to dynamical and chemical processes in CCMs and CTMs
Chemical climate models Earth's ozone layer. Coupled chemical plan Simulated atmospheric flow Ozone concentration
2014/12/9
Chemistry-climate models (CCMs) are commonly used to simulate the past and future development of Earth's ozone layer. The fully coupled chemistry schemes calculate the chemical production and destruct...
Mammalian Species Origin and Geographical Dispersal Patterns Correlate With Changes in Chromosome Structure, Exemplified in Lemurs (Madagascar) and Bats (Worldwide)
Bats Biogeography Chromosomes Karyotypes Lemurs Speciation
2014/10/22
The origin and geographical distribution of mammalian species (my examples are lemurs and bats) correlate with predictable chromosomal structural changes (KFT=karyotypic fission theory). Chromosome st...
Paleoceanography and paleoenvironmental changes of the Cenomanian-Turonian boundary interval (94-93 Ma): The record of Oceanic Anoxic Event 2 in the central and eastern parts of the Western Interior Sea
