downwelling_photon_spherical_irradiance_per_unit_wavelength_in_sea_water
Definition
- Downwelling radiation is radiation from above. It does not mean "net downward". The sign convention is that "upwelling" is positive upwards and "downwelling" is positive downwards. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength. Photon spherical irradiance is the photon flux incident on unit area of a hemispherical (or "2-pi") collector. The direction ("up/downwelling") is specified. Radiation incident on a 4-pi collector has a standard name referring to "omnidirectional spherical irradiance". A photon flux is specified in terms of numbers of photons expressed in moles.
Note
- Mapping to be determined
