farms.utilities.calc_beta

farms.utilities.calc_beta(aod, alpha)[source]

Calculate the Angstrom turbidity coeff. (beta).

Parameters:

aod (np.ndarray) – Array of aerosol optical depth (AOD) values. Shape must match alpha.
alpha (np.ndarray) – Array of angstrom wavelength exponent values. Shape must match aod.

Returns:

beta (np.ndarray) – Array of Angstrom turbidity coeff., i.e. AOD at 1000 nm. Shape will be same as aod and alpha. Will be tested for compliance with the mandatory interval [0, 2.2].
