| Definition | The surface called 'surface' means the lower boundary of the atmosphere. 'Water' means water in all phases, including frozen i.e. ice and snow. Downwelling radiation is radiation from above. It does not mean 'net downward'. 'spectral' means per unit wavelength or as a function of wavelength; spectral quantities are sometimes called 'monochromatic'. Radiation wavelength has standard name radiation_wavelength. Photon spherical irradiance is the photon flux incident on unit area of a hemispherical (or '2-pi') collector. A photon flux is specified in terms of numbers of photons expressed in moles. | ||
