We used the Terrestrial Ecosystem Model (TEM, version 4.0) to estimate net primary production (NPP) in China for contemporary climate and NPP responses to elevated CO2 and climate changes projected by three atmospheric general circulation models (GCMs): Goddard Institute for Space Studies (GISS), Geophysical Fluid Dynamic Laboratory (GFDL) and Oregon State University (OSU). For contemporary cli...

The main text introduces the model framework for ICE age Chemistry And Proxies (ICECAP), a project focused on paleo-chemistry at and since the Last Glacial Maximum. The framework includes the GEOS-Chem 3-D global chemical transport model (CTM; http://www.geos-chem.org), driven by archived meteorology from the NASA Goddard Institute for Space Sciences (GISS) ModelE general circulation model (GCM...

A new aerosol microphysical module MATRIX, the Multiconfiguration Aerosol TRacker of mIXing state, and its application in the Goddard Institute for Space Studies (GISS) climate model (ModelE) are described. This module, which is based on the quadrature method of moments (QMOM), represents nucleation, condensation, coagulation, internal and external mixing, and cloud-drop activation and provides...

6 [1] Understanding the effects of global climate change on regional air quality is central in 7 future air quality planning. We report here on the use of the Goddard Institute for Space 8 Studies (GISS) general circulation model (GCM) III to drive the GEOS-CHEM global 9 atmospheric chemical transport model to simulate climatological present-day aerosol 10 levels over the United States. Evaluat...

The ability of five, global coupled climate models to simulate important atmospheric circulation characteristics in the Southern Hemisphere for the period 1960–1999 is assessed. The circulation features examined are the Southern Hemisphere annular mode (SAM), the semi-annual oscillation (SAO) and the quasi-stationary zonal wave 3 (ZW3). The models assessed are the National Center for Atmospheri...

Results from a series of Goddard Institute for Space Studies (GISS) General Circulation Models (GCMs) are used to assess climate variability in the pre-anthropogenic Holocene, the interval following the end of the last glacial beginning roughly 11.5 kyr BP. In particular, we focus on the forced aspects of this variability. The principle forcings are orbital, solar, volcanic and events (such as ...
