We also make use of two lengthy control simulations conducted with CESM1 under constant 1850 radiative conditions: a 2200 - year control run using the fully - coupled configuration (hereafter termed the «coupled control run»), and a 2600 - year control run using only the atmospheric model component coupled to
the land model component from CESM1 with a specified repeating seasonal cycle of sea surface temperatures (SSTs) and sea ice conditions taken from the long - term climatology of the fully - coupled control run (hereafter termed the «atmospheric control run»).
In R1,
the land model component was the OSU land model with the UMD 13 - class land - use (vegetation type) data set.

Coverage includes original paleoclimatic, diagnostic, analytical and numerical
modeling research on the structure and behavior of the atmosphere, oceans, cryosphere, biomass and
land surface as interacting
components of the dynamics of global climate.
Evaluation of the
land surface
component in coupled
models is severely limited by the lack of suitable observations.
Earth system
models, particularly the
land and atmosphere
components that intersect precisely where we all live, grow our food and operate our economies, need to be developed together, with their coupled behavior considered from the start.
> We analyze and compare the monthly global
land - sea surface temperature datasets HADCRUT3 and HADCRUT4 for 1850 - 2010 by subtracting two analytically
modeled components and demonstrating with a suitable low - pass filter that the residue contains no significant fluctuations with periods longer than the 22 - year Hale cycle.
Climate
models are like weather
models for the atmosphere and
land, except they have to additionally predict the ocean currents, sea - ice changes, include seasonal vegetation effects, possibly even predict vegetation changes, include aerosols and possibly atmospheric chemistry, so they are not like weather
models after all, except for the atmospheric dynamics,
land surface, and cloud / precipitation
component.
Compared to emission
modeling, definitions of relevant variables and base year data differ more greatly across the IAMs for the
land use
components.
While the historical performance of ocean
models can be benchmarked against global inventories of ocean carbon, only recently have equivalently robust global estimates been developed for some
components of
land carbon storage (Saatchi et al 2011) and soils, the largest reservoir, remains very sparsely sampled.
The RCPs should provide information on all
components of radiative forcing that are needed as input for climate
modeling and atmospheric chemistry
modeling (emissions of greenhouse gases, air pollutants and
land use).
I wanted to have the
land be somewhat realistic, so instead of using a completely idealized
land surface I wanted to use the community
land model (CLM)
component of CESM, which calculates surface sensible and latent heat fluxes based on soil and vegetation types.
Soil moisture is a key
component in the
land surface schemes in climate
models, since it is closely related to evapotranspiration and thus to the apportioning of sensible and latent heat fluxes.
Called ModelE, it provides the ability to simulate many different configurations of Earth System
Models — including interactive atmospheric chemistry, aerosols, carbon cycle and other tracers, as well as the standard atmosphere, ocean, sea ice and
land surface
components.
Use the calculated fluxes to force the surface
component of a climate
model (without the atmosphere), including the ocean, sea ice, and
land subsystem
models, for the baseline (preindustrial) and the doubled CO2 forcing.
We attempted to apply irrigation realistically in space and time to the
land surface
component of a global atmosphere general circulation
model, the GISS ModelE, allowing the
model to compute explicitly the water and energy dynamics of the

The Earth — with its myriad shifting atmospheric, oceanic,
land and ice
components — presents an extraordinarily complex system to simulate using computer
models.
Each Educare center is a private - public collaboration that brings together a philanthropic leader or leaders to spearhead the capital campaign, a programmatic provider of Head Start and Early Head Start services to implement the core
components of the Educare
model, and a public school or district to provide
