Changes in precipitation patterns influence natural selection at global scale
precipitation patterns natural selection global scale
2017/3/14
What matters more for the evolution of plants and animals, precipitation or temperature? Scientists have found a surprising answer: rain and snow may play a more important role than how hot or cold it...
OPEN STREET MAP DATA AS SOURCE FOR BUILT-UP AND URBAN AREAS ON GLOBAL SCALE
Built-up Areas Urban Areas Volunteered Geographic Information OpenStreetMap Spatial Data Processing
2016/11/8
Many types of applications require information about built-up areas and urban areas. Thus, there is a need for a global, vector-based, up-to-date, and free dataset of high resolution and accuracy. The...

GOME-2 observations of oxygenated VOCs: what can we learn from the ratio glyoxal to formaldehyde on a global scale?
GOME-2 oxygenated VOCs the ratio glyoxal a global scale
2010/11/3
Collocated data sets of glyoxal (CHO.CHO) and formaldehyde (HCHO) were retrieved for the first time from measurements of the Global Ozone Monitoring Experiment-2 (GOME-2) during the first two years of...
Global-scale wreath-building dynamos in stellar convection zones
convection interiors magnetic fields stars rotation
2010/11/10
When stars like our Sun are young they rotate rapidly and are very magnetically active. We explore dynamo action in rapidly rotating suns with the 3-D MHD anelastic spherical harmonic (ASH) code. The ...
