What does radiometrically mean?
Radiometrically is an adverb meaning “by means of radiometry” or “using radiometric measurement.” It describes methods that quantify radiation, often to infer temperature, distance, composition, or other physical properties. The term is especially common in remote sensing and satellite imaging, where images may be radiometrically corrected to compensate for atmospheric effects, sensor differences, and illumination variations. It also appears in thermal imaging, astronomy, and scientific instrumentation. The word is more technical than everyday language: speakers usually use “measured,” “corrected,” “calibrated,” or “compared” with it. Although radiometrically is closely related to radiometric, its use is specifically adverbial, describing how an action or process is carried out. Its specialized vocabulary makes it especially useful in technical writing and precise scientific discussion.

- Using radiometry or radiometric measurement.
"The satellite images were radiometrically corrected to account for differences in atmospheric conditions."
"The instrument radiometrically measured the surface temperature of the lava flow."
"Researchers compared the sites radiometrically before selecting a representative sample."
Radiometrically measuring the warmth of a distant object is the principle behind some thermal cameras and temperature-sensitive astronomy.

Etymology of radiometrically
Radiometrically was formed in English by adding the suffix -ally to radiometric. Radiometric in turn comes from radiometry, the measurement of radiation, which is associated with Latin radius, “ray,” and the combining form metric, from Greek metron, “measure.” Related English words include radiation, radiant, radius, and radiometer. The shared sense across these words is that of rays or radiation and the measurement or transmission of that energy.
