CAM’s “resolution” variable defines the horizontal grid and the dynamical core, which in this case is the Finite Volume core, which is defined on a logically rectangular grid with spacing ∼0.9∘ in latitude and 1.25∘ in longitude. The land model (CLM5) uses the same grid. The...
The CESM components can be run on a variety of grids. Often, one global grid is used for the atmosphere and land, and a second global grid is used for the ocean and sea ice. The ice-sheet component has a regional grid for each active ice sheet. Currently, CESM allows simulations only...
To compare the differences between high- and low-resolution models, the outputs from high-resolution models are interpolated to the corresponding low-resolution grid. 2.2 Double-ITCZ Index (DII) To quantify the double-ITCZ bias, we use a widely adopted double-ITCZ Index (DII), also called ...
forced by the observed present-day sea surface temperature and sea ice (results are similar if coupled simulations are used). The in-cloud ice number is constructed by averaging monthly cloud ice numbers for grid points with a cloud ice mixing ratio greater than 0.01 part-per-million by mass...
In this section we will run a case with user-supplied files. The land model domain is set in North-Rhine Westphalia, Germany with a grid resolution of 300 latitudes by 300 longitudes. The atmospheric forcing data is based from theCOSMO-REA6dataset. ...

However, contradicting with the observation, in the Community Earth System Model version 2 (CESM2), the SSTA centers of both types of El Nio are close to the CP area, which makes them difficult to be separated, i.e., the CESM2 shows a relatively poor depiction of the realistic El Nio...
Sea ice extent (SIE) is defined as the total area covered by grid points that have the sea ice concentration (SIC) greater than 15%. In this study, our focus is on the September SIE over the Northern Hemisphere (north of 30N). In order to isolate the year-to-year variability of Sep...
White or light garage tiles can stain from street tar and performance tires. Because of this, many of our customer use a black parking area to avoid this issue. Contact us Hebei Fu Xuan Trade Co., Ltd. Contact Supplier Click here to contact the supplier through an ...
