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.
Comparisons with automatic instruments at German stations revealed that during summer the differences of the two measurement systems can reach up to 4 h per day. The mean difference was −0.23 h, i.e. the measurements of the Campbell–Stokes recorder are larger than the automatic.
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.

Instead, the air is full of red dust, blown into the atmosphere by high winds, [22] so its sky color is mainly determined by a Mie Scattering process, resulting in more blue hues than an Earth sunset. One study also reported that Martian dust high in the atmosphere can reflect sunlight up to two hours after the Sun has set, casting a diffuse ...
Examples of the instrument can be found with a 0° to 90° graduation or with two mirrored 0° to 45° segments centred on the midpoint of the arc. [ 4 ] The instrument has three vanes, a horizon vane (A in Figure 8 ) which has an opening in it to observe the horizon, a shadow vane (B) to cast a shadow on the horizon vane and a sighting vane (C ...
The timeline of meteorology contains events of scientific and technological advancements in the area of atmospheric sciences.The most notable advancements in observational meteorology, weather forecasting, climatology, atmospheric chemistry, and atmospheric physics are listed chronologically.
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]
