Optimal Taxes on Fossil Fuel in General Equilibrium
Climate change optimal policy optimal taxes
2014/3/18
We analyze a dynamic stochastic general-equilibrium (DSGE) model with an externality—through climate change—from using fossil energy. Our central result is a simple formula for the marginal externalit...
Aluminium in an ocean general circulation model compared with the West Atlantic Geotraces cruises
Aluminium Dust deposition Modelling PISCES Biogenic sil-ica GEOTRACES
2012/2/28
A model of aluminium has been developed and implemented in an Ocean General Circulation Model (NEMO-PISCES). In the model, aluminium enters the ocean by means of dust deposition. The internal oceanic ...

2014/5/20
Most of current general circulation models (GCMs) show a remarkable positive precipitation bias over the southwestern equatorial Indian Ocean (SWEIO), which can be thought of as a westward expansion o...
Interpreting the cloud cover – aerosol optical depth relationship found in satellite data using a general circulation model
the cloud cover aerosol optical depth relationship satellite data a general circulation model
2010/8/16
Statistical analysis of satellite data shows a positive correlation between aerosol optical depth (AOD) and total cloud cover (TCC). Reasons for this relationship have been disputed in recent literatu...
Sensitivity of tracer transport to model resolution, prescribed meteorology and tracer lifetime in the general circulation model ECHAM5

2010/8/12
Atmospheric transport of traces gases and aerosols plays an important role in the distribution of air pollutants and radiatively active compounds. For model simulations of chemistry-climate interactio...
Two-dimensional reconstruction of past sea level (1950–2003) from tide gauge data and an Ocean General Circulation Model
past sea level Ocean General Circulation Model Two-dimensional
2009/12/3
A two-dimensional reconstruction of past sea level is proposed at yearly interval over the period 1950–2003 using tide gauge records from 99 selected sites and 44-year long (1960–2003) 2°×2° sea level...
Aerosol indirect effects – general circulation model intercomparison and evaluation with satellite data
Aerosol indirect effects general circulation model satellite data
2009/11/19
Aerosol indirect effects continue to constitute one of the most important uncertainties for anthropogenic climate perturbations. Within the international AEROCOM initiative, the representation of aero...
