An investigation of the sub-grid variability of trace gases and aerosols for global climate modeling
the sub-grid variability trace gases and aerosols global climate modeling
2010/8/16
One fundamental property and limitation of grid based models is their inability to identify spatial details smaller than the grid cell size. While decades of work have gone into developing sub-grid tr...
