Northern Hemisphere Glaciation during the Globally Warm Early Late Pliocene [PDF]

, 2013
The early Late Pliocene (3.6 to ∼3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO₂ concentrations were comparable to today's and global climate was warmer.

Bayesian evaluation of the southern hemisphere radiocarbon offset during the holocene [PDF]

, 2009
While an interhemispheric offset in atmospheric radiocarbon levels from AD 1950–950 is now well established, its existence earlier in the Holocene is less clear, with some studies reporting globally uniform 14C levels while others finding Southern ...

Storm-Time Behaviour of Meso-Scale Field-Aligned Currents: Case Study with Three Geomagnetic Storm Events

Journal of Astronomy and Space Sciences, 2019
Challenging Minisatellite Payload (CHAMP) satellite magnetic data are used to investigate the latitudinal variation of the storm-time meso-scale field-aligned currents by defining a new metric called the FAC range.

Ice particle production in mid-level stratiform mixed-phase clouds observed with collocated A-Train measurements [PDF]

Atmospheric Chemistry and Physics, 2018
Collocated A-Train CloudSat radar and CALIPSO lidar measurements between 2006 and 2010 are analyzed to study primary ice particle production characteristics in mid-level stratiform mixed-phase clouds on a global scale.

FOREST CARBON SINKS IN THE NORTHERN HEMISPHERE

Ecological Applications, 2002
There is general agreement that terrestrial systems in the Northern Hemisphere provide a significant sink for atmospheric CO2; however, estimates of the magnitude and distribution of this sink vary greatly. National forest inventories provide strong, measurement-based constraints on the magnitude of net forest carbon uptake.

Synthesis of the Northern Hemisphere of Amphidinolide H2 [PDF]

Synthesis, 2006
The stereoselective synthesis of a fully functionalized northern hemisphere of the marine natural product amphidinolide H2 is described. A vinylogous Mukaiyama aldol reaction and enzymatic desymmetrization of a meso compound are the key steps in the fragment syntheses. A stereoselective acetate aldol coupling and a 1,3-anti-reduction of the resulting β-

On the characteristics of astronomical refraction in the northern hemisphere [PDF]

Symposium - International Astronomical Union, 1979
The astronomical refraction mainly depends on the vertical structure or the height profile of atmospheric density. Concerning the vertical structure of atmospheric density, various hypotheses were presented during the last century. Among them Newton's hypothesis of equal temperature and Ivory's one that temperature diminishes at a uniform rate with ...
