It is the work of commercial enterprises specializing in scientific instrumentation — Googling «
ir radiometry company» returned nearly a million hits as of writing.
The Physikalisch - Technische Bundesanstalt (PTB) has now developed a mathematical procedure which yields clearly improved results and can be applied in numerous fields
of radiometry and photometry.
One was from the Sounding of the Atmosphere using Broadband
Emission Radiometry (SABER) instrument riding on NASA's TIMED satellite.
There remains an unresolved 4.5 W / m ^ 2 difference between the TIM and other space - borne radiometers, and this difference is being studied by the TSI and
radiometry communities.»
ZSD can also be estimated from airborne or
satellite radiometry, thus greatly increasing the geographic and temporal availability of water clarity observations.
Microwave
radiometry data are used to construct brightness temperatures: an indication of the intensity of electromagnetic energy at a particular wavelength that filters up through the atmosphere and reaches the satellite's sensor.

Endless forays must be made on all scientific fronts — geology, biology, paleontology, astronomy, chemistry, physics, meteorology, genetics, sedimentology,
radiometry and the like — either to try to discredit evolution or to defend creation.
Another type of device, the maser (acronym for «microwave amplification by stimulated emission of radiation») has proved useful in such areas as radio astronomy, microwave
radiometry, and long - distance communications.
Radiometry is a technique complementary to radar in which the instrument emits a signal and then detects that signal after it bounces off a surface.
