SimpleAbsorbedShortwave

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

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:

current_time
depth: Depth at grid centers (m)
depth_bounds: Depth at grid interfaces (m)
diagnostics: Dictionary access to all diagnostic variables
elapsed_time
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.
timestep_in_seconds: Return a float value representing the timestep in units of seconds

Methods

`add_diagnostic`(name[, value])	Create a new diagnostic variable called `name` for this process and initialize it with the given `value`.
`add_input`(name[, value])	Create a new input variable called `name` for this process and initialize it with the given `value`.
`add_subprocess`(name, proc[, verbose])	Adds a single subprocess to this process.
`add_subprocesses`(procdict)	Adds a dictionary of subproceses to this process.
`compute`()	Computes the tendencies for all state variables given current state and specified input.
`compute_diagnostics`([num_iter])	Compute all tendencies and diagnostics, but don't update model state.
`declare_diagnostics`(diaglist)	Add the variable names in `inputlist` to the list of diagnostics.
`declare_input`(inputlist)	Add the variable names in `inputlist` to the list of necessary inputs.
