received radiant flux density

symbols: $I$, $E$, $\phi_{0}$, unit: $\pu{W m-2}$
synonyms: incident flux density, irradiance
https://doi.org/10.1351/goldbook.08280
Radiant power incident on unit area.
Notes:
  1. SI unit: \(\pu{W m-2}\).
  2. In atomic absorption spectroscopy incident flux density at a given wavelength is given the symbol \(\phi_{0}(\lambda)\).
