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.

Objectives of Work

Proper organizing of national terminologies
on radiometric calibration of spaceborne
sensors
 Establishing a unique correspondence
between Russian and American terms and
definitions
 Development of a formal document (bilingual explanatory dictionary)

Radiometric Terms Unification
in the USA
In the 1966-1975, 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 1966.
Together with associates, Nicodemus has expanded
the logic and codified the concepts, both in the
Military Standard on Infrared Terms and Definitions,
AD-784 341 (December 1971) and Reference Book of
Radiometric Nomenclature (Irving J. Spiro, John
Wiley and Sons,1975)

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 1987. 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).

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.
