  2. Storm Prediction Center - Wikipedia

    en.wikipedia.org/wiki/Storm_Prediction_Center

    The Storm Prediction Center (SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), [1] which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC).

  3. Integrated Surface Database - Wikipedia

    en.wikipedia.org/wiki/Integrated_Surface_Database

    Integrated Surface Database (ISD) is global database compiled by the National Oceanic and Atmospheric Administration (NOAA) and the National Centers for Environmental Information (NCEI) comprising hourly and synoptic surface observations compiled globally from ~35,500 weather stations; it is updated, automatically, hourly. The data largely date ...

  4. Automated Meteorological Data Acquisition System - Wikipedia

    en.wikipedia.org/wiki/Automated_Meteorological...

    Automated Meteorological Data Acquisition System (AMeDAS), commonly known in Japanese as "アメダス" (amedasu), is a high-resolution surface observation network developed by the Japan Meteorological Agency (JMA) used for gathering regional weather data and verifying forecast performance. The system began operating on 1 November 1974, and ...

  5. Surface weather observation - Wikipedia

    en.wikipedia.org/wiki/Surface_weather_observation

    Surface weather observations are the fundamental data used for safety as well as climatological reasons to forecast weather and issue warnings worldwide. [1] They can be taken manually, by a weather observer, by computer through the use of automated weather stations , or in a hybrid scheme using weather observers to augment the otherwise ...

  6. Convective storm detection - Wikipedia

    en.wikipedia.org/wiki/Convective_storm_detection

    The resulting momentum equation is integrated over height to yield the kinetic energy of the parcel on descending to the surface and is found to be the negative CAPE of a dry air parcel injected into the storm, plus de motion of the convective cell. S. R. Stewart, from NWS, has published in 1991 an equation relating VIL and the echo tops that ...

    Research area of the research center consists of meteorological radar, surface meteorology observation and application, multi-source meteorological data fusion, lightning monitoring and early warning, concentrating on meteorological radar signal processing, meteorological radar data quality control and calibration technique, weather radar ...

  8. Remote sensing in geology - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing_in_geology

    Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...

  9. Ground truth - Wikipedia

    en.wikipedia.org/wiki/Ground_truth

    The term "ground truthing" refers to the process of gathering the proper objective (provable) data for this test. Compare with gold standard. For example, suppose we are testing a stereo vision system to see how well it can estimate 3D positions. The "ground truth" might be the positions given by a laser rangefinder which is known to be much ...
