Observation
Observation is typically made via different 'channels' of the Electromagnetic spectrum, in particular, the Visible and Infrared portions.
Some of these channels include :
- Visible and Near Infrared: 0.6 μm – 1.6 μm – For recording cloud cover during the day
- Infrared: 3.9 μm – 7.3 μm (Water Vapour), 8.7 μm, – 13.4 μm (Thermal imaging)

Famous quotes containing the word observation:
“It is, in both cases, that a spiritual life has been imparted to nature; that the solid seeming block of matter has been pervaded and dissolved by a thought; that this feeble human being has penetrated the vast masses of nature with an informing soul, and recognised itself in their harmony, that is, seized their law. In physics, when this is attained, the memory disburthens itself of its cumbrous catalogues of particulars, and carries centuries of observation in a single formula.”
—Ralph Waldo Emerson (1803–1882)
“Laws and customs may be creative of vice; and should be therefore perpetually under process of observation and correction: but laws and customs cannot be creative of virtue: they may encourage and help to preserve it; but they cannot originate it.”
—Harriet Martineau (1802–1876)
“He is one of those that deserve very well, but are very awkward at putting their Talents within the Observation of such as should take Notice of them.”
—Richard Steele (1672–1729)
