Blackbody r

Purpose

Computes black body radiance and brightness temperature.

Synopsis

v = blackbody_r(wv,temp,flag,wave)

temp = blackbody_r(wv,v,flag,wave)

Description

BLACBODY_R is used to calculate randiance from the Planck function in units of W/(m^2 sr cm^-1) or uW/(m^2 sr um^-1). BLACBODY_R can be also be used to calculate brightness temperature from the inverse Planck function for inputs in units of W/(m^2 sr cm^-1) or uW/(m^2 sr um^-1). Calculations can be performed for axis units in wavenumbers (1/cm) or in microns (um). See I/O specific inputs/outputs below.

Input/Output

• v = blackbody_r(wv,temp);

wv = 1xN row vector of wavelengths (um).

temp = Kx1 vector of temperatures (K).

v = KxN row vector of BB radiance uW/(m^2 sr um^-1) = uflicks

• temp = blackbody_r(wv,v,2);

wv = 1xN row vector of wavelengths (um).

v = KxN matrix of BB radiance uW/(m^2 sr um^-1) = uflicks

temp = KxN matrix of temperatures (K).

• v = blackbody_r(nu,temp,1,2);

nu = 1xN row vector of wavenumbers (1/cm).

temp = Kx1 vector of temperatures (K).

v = KxN row vector of BB radiance W/(m^2 sr cm^-1)

• temp = blackbody_r(nu,v,2,2);

nu = 1xN row vector of wavenumbers (1/cm).

v = KxN row vector of BB radiance W/(m^2 sr cm^-1)

temp = KxN vector of temperatures (K).
