3. Introduction
The necessity for a uniform usage of terms and definitions in the area of radiometric calibrations of spaceborne sensors becomes crucial for large-scale international space programs, in particular, for space research being undertaken jointly by the United States and the Russian Federation. 3

6. Radiometric Terms Unification in the USA
In the , Fred Nicodemus, lately of the Naval Weapons Laboratory at China Lake, CA, then with the NBS has done an outstanding job in solidifying the concepts proposed (as the committee action) in Together with associates, Nicodemus has expanded the logic and codified the concepts, both in the Military Standard on Infrared Terms and Definitions, AD (December 1971) and Reference Book of Radiometric Nomenclature (Irving J. Spiro, John Wiley and Sons,1975)

9. A good basis for the international terminology in optical phenomenology, radiometry and optical measurement technology is The International Lighting Vocabulary along with some other publications by the International Lighting Commission (CIE).
Unfortunately, the latest edition (4th) of The International Lighting Vocabulary had been published in Some suggestions had been rejected by the practice (e.g. spectral radiance rather than the suggested term spectral concentration of radiance), while some other concepts believed to be rarely used in practice proved to be quite customary in science terminology (e.g., bidirectional reflectance distribution function, BRDF).

15. Conclusion
Currently, the document is submitted to a team of American experts for comments and corrections. A draft of this volume is presented at this meeting. A draft of the second part of the document has been developed that covers terms and definitions relating to measurements, analysis of data and uncertainties in radiometric calibration of spaceborne optoelectronic sensors.
We would be happy to share the document (Vol. I) with you and your comments would be highly appreciated.
