  2. Surface exposure dating - Wikipedia

    en.wikipedia.org/wiki/Surface_exposure_dating

    Surface exposure dating is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth's surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows, meteorite impacts, rock slides, fault scarps, cave development, and other geological events.

    en.wikipedia.org/wiki/GRIB

    GRIB (GRIdded Binary or General Regularly-distributed Information in Binary form [1]) is a concise data format commonly used in meteorology to store historical and forecast weather data. It is standardized by the World Meteorological Organization 's Commission for Basic Systems, known under number GRIB FM 92-IX, described in WMO Manual on Codes ...

  4. 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 ...

    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 ...

    en.wikipedia.org/wiki/METAR

    The METAR format was introduced internationally on 1 January 1968, and has been modified a number of times since. North American countries continued to use a Surface Aviation Observation (SAO) for current weather conditions until 1 June 1996, when this report was replaced with an approved variant of the METAR agreed upon in a 1989 Geneva agreement.

  7. SYNOP - Wikipedia

    en.wikipedia.org/wiki/SYNOP

    SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .

  8. History of surface weather analysis - Wikipedia

    en.wikipedia.org/wiki/History_of_surface_weather...

    Other countries then began preparing surface analyses. In Australia, the first weather map showed up in print media in 1877. [10] Japan's Tokyo Meteorological Observatory, the forerunner of the Japan Meteorological Agency, began constructing surface weather maps in 1883. [11] The London Times published the first weather map on April 1, 1875. [12]

    A stock of nordmarkite (quartz-alkali syenite) of Triassic age, in the Gevanim Valley, Makhtesh Ramon, southern Israel.. In geology, a stock is an igneous intrusion that has a surface exposure of less than 100 square kilometres (40 sq mi), [1] [2] differing from batholiths only in being smaller.
