  2. Present weather sensor - Wikipedia

    en.wikipedia.org/wiki/Present_weather_sensor

    There are at least two types of devices used to detect precipitation: A light emitting diode weather identifier (LEDWI) sensor measures the scintillation pattern of the precipitation falling through the sensor's infrared beam (approximately 50 millimeters in diameter) and determines from a pattern analysis of the particle size and fall velocity whether the precipitation is rain or snow.

  3. Weather radar - Wikipedia

    en.wikipedia.org/wiki/Weather_radar

    Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

  4. Arduino - Wikipedia

    en.wikipedia.org/wiki/Arduino

    Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.

  5. Rain gauge - Wikipedia

    en.wikipedia.org/wiki/Rain_gauge

    Most modern rain gauges generally measure the precipitation in millimetres in height collected during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch. [16] Rain gauge amounts are read either manually or by automatic weather station ...

  6. Intensity-duration-frequency curve - Wikipedia

    en.wikipedia.org/wiki/Intensity-duration...

    These curves are commonly used in hydrology for flood forecasting and civil engineering for urban drainage design. However, the IDF curves are also analysed in hydrometeorology because of the interest in the time concentration or time-structure of the rainfall , [ 2 ] [ 3 ] but it is also possible to define IDF curves for drought events.

  7. 3D printing - Wikipedia

    en.wikipedia.org/wiki/3D_printing

    3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

  8. Parametrization (climate modeling) - Wikipedia

    Field of cumulus clouds. Weather and climate model gridboxes have sides of between 5 kilometres (3.1 mi) and 300 kilometres (190 mi). A typical cumulus cloud has a scale of less than 1 kilometre (0.62 mi), and would require a grid even finer than this to be represented physically by the equations of fluid motion.

  9. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    The bluish color is evidence that such scattering is being produced by rain-sized droplets in the cloud. A cumulonimbus cloud emitting green is a sign that it is a severe thunderstorm, [21] capable of heavy rain, hail, strong winds and possible tornadoes. The exact cause of green thunderstorms is still unknown, but it could be due to the ...
