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-

Copepods in the Northern Hemisphere [PDF]
Nature, 1925 IT has long been recognised that the distribution of freshwater copepods has been profoundly influenced by the incidence of the glacial period, since the lake-districts which they inhabit are to a large extent postglacial catchment basins. It so happens that there is a general correspondence between the three leading sub-orders and the three principal ...

Mesoscale temperature fluctuations in the Southern Hemisphere stratosphere [PDF]
Atmospheric Chemistry and Physics, 2008 Isentrope surfaces in the Southern Hemisphere stratosphere reveal that air parcels undergo mesoscale temperature fluctuations that depend on latitude and season.

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 ...

Pre-LGM Northern Hemisphere ice sheet topography [PDF]
Climate of the Past, 2013 We here reconstruct the paleotopography of Northern Hemisphere ice sheets during the glacial maxima of marine isotope stages (MIS) 5b and 4.We employ a combined approach, blending geologically based reconstruction and numerical modeling, to arrive at ...

Numerical simulations of oceanic oxygen cycling in the FAMOUS Earth-System model: FAMOUS-ES, version 1.0 [PDF]
Geoscientific Model Development, 2014 Addition and validation of an oxygen cycle to the ocean component of the FAMOUS climate model are described. At the surface, FAMOUS overestimates northern hemisphere oxygen concentrations whereas, at depth, the southern hemisphere values are too low ...

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing
Advanced Science, EarlyView.Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

Change in Earth’s solar climate over the period from 1900 to 2100
Solar-Terrestrial PhysicsThe paper presents the results of the analysis of changes in Earth’s solar climate over the period from 1900 to 2100. It has been determined that the annual meridional gradient of irradiation intensity from 1900 to 2100 and latitudinal differences in the
