class climlab.radiation.absorbed_shorwave.SimpleAbsorbedShortwave(insolation=341.3, albedo=0.3, **kwargs)

Bases: EnergyBudget

A class for the shortwave radiation process in a one-layer EBM. The basic assumption is that all the shortwave absorption occurs at the surface.

Computes the diagnostic ASR (absorbed shortwave radiation) from the formula self.ASR = (1-self.albedo) * self.insolation and applies this as a tendency on the surface temperature self.Ts

albedo and insolation are given as inputs. These should either be scalars or have same dimensions as state variable Ts

User can supply constants, or link to diagnostics of specific insolation and albedo processes.

Attributes:

depth

Depth at grid centers (m)

depth_bounds

Depth at grid interfaces (m)

diagnostics

Dictionary access to all diagnostic variables

input

Dictionary access to all input variables

lat

Latitude of grid centers (degrees North)

lat_bounds

Latitude of grid interfaces (degrees North)

lev

Pressure levels at grid centers (hPa or mb)

lev_bounds

Pressure levels at grid interfaces (hPa or mb)

lon

Longitude of grid centers (degrees)

lon_bounds

Longitude of grid interfaces (degrees)

timestep

The amount of time over which step_forward() is integrating in unit seconds.
