The other instrument is a Marvin sunshine recorder. Older recorders required a human observer to interpret the results; recorded results might differ among observers. Modern sunshine recorders use electronics and computers for precise data that do not depend on a human interpreter. Newer recorders can also measure the global and diffuse radiation.
Remote sensing instruments collect data from weather events some distance from the instrument and typically stores the data where the instrument is located and often transmits the data at defined intervals to central data centers. In 1441, King Sejong's son, Prince Munjong, invented the first standardized rain gauge.
An astronomical instrument is a device for observing, measuring, or recording astronomical data. [ citation needed ] They are used in the scientific field of astronomy , a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.
Actual sunset: Two minutes before the Sun disappears below the horizon. Sunset (or sundown) is the disappearance of the Sun at the end of the Sun path, below the horizon of the Earth (or any other astronomical object in the Solar System) due to its rotation.
Sunset provisions have been used extensively throughout legal history. [2] The idea of general sunset provisions was discussed extensively in the late 1970s. [3] Sunset clauses with an effective extension review process have been argued as a safeguard of democracy to ensure emergency provisions, such as state of emergency, remain temporary. [4]
The heliotrope is an instrument that uses a mirror to reflect sunlight over great distances to mark the positions of participants in a land survey. The heliotrope was invented in 1821 by the German mathematician Carl Friedrich Gauss.
An actinometer instrument from the 1800s designed by John Herschel and used to estimate the temperature of the Sun's surface. An actinometer is an instrument that can measure the heating power of radiation. Actinometers are used in meteorology to measure solar radiation as pyranometers, pyrheliometers and net radiometers.
A sunset industry is an industry in decline, one that has passed its peak or boom periods. As one example, analogue recording technologies for audio or video have been supplanted by digital equivalents; although analogue equipment is still offered, sales have declined dramatically and are not expected to recover, so this segment of the market has been branded a 'sunset industry'.
