This is the second part of two papers which discusses some of the applications of the techniques and standards described in part 1. In particular, the realization of spectral irradiance and radiance scales and the radiometric measurement of thermodynamic temperature. The paper also briefly describes some new ways of improving the dissemination of some of these scales both in terms of accuracy and user convenience. It also discusses some specific needs of application areas such as Earth observation and difficulties associated with terminology such as traceability which will need to be addressed in the future to ensure progress at the NMIs is fully exploited in industry. In addition to the more standard radiometric application areas, a brief overview of the demands of new application areas such as appearance are also introduced.
