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 London Times published the first weather map on April 1, 1875. [12] In the United States, the 1876 Centennial Exposition in Philadelphia, Pennsylvania demonstrated that daily weather map transmission via telegraph could be accomplished. The New York Daily Graphic published weather maps from mid-1879 through the summer of 1882. By 1894 ...
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
On the top right corner of the model for a surface weather map is the pressure, showing the last two integer digits of the pressure in millibars, or hectopascals, along with the first decimal. For instance, if the pressure at a certain location is 999.7 hPa, the pressure portion of the station model will read 997.
A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.

The initial version of Global Historical Climatology Network was developed in the summer of 1992. [3] This first version, known as Version 1 was a collaboration between research stations and data sets alike to the World Weather Records program and the World Monthly Surface Station Climatology from the National Center for Atmospheric Research.

January – A study by the Northern Tornadoes Project and the University of Western Ontario released information on Treefall Identification and Direction Analysis (TrIDA) maps, a new artificial intelligence (A.I.) application tested using Canadian tornadoes as the machine learning data. TrIDA maps had approximately 80% verification rates. [72 ...
