ClimateStations.com - Descriptive Climatological Graphs and Charts for Ten Major Metropolitan Area Weather Stations Distributed Across the United States

Climatestations.com was originally created by meteorologist Charles Fisk with the primary purpose to present graphical depictions (floating-bar graphs) of the remarkably lengthy and 99.6 percent intact year-to-year daily history of maximum and minimum temperatures for Minneapolis-St. Paul MN, dating back nearly 200 years to 1820.  Also included in the initial MSP site were daily series, by year, of other parameters, such as temperature anomalies, precipitation, snowfall, and snow depth, the latter three subject to their availability and form in the archives.

Over time, nine additional stations, most with climatic histories approaching or exceeding a century in length have been added (New York Central Park, Chicago, Los Angeles, San Francisco, San Diego, and Portland), to go with those of Las Vegas, Miami, and Seattle, the latter three with daily periods of record back to the late 1940’ s.

Other statistical graphics’ types, not to mention more variables (e.g. winds – mean vector, mean scalar; also relative humidities, etc.,) have been introduced, the most important graphic-type being “hour-by-month climograms”, portraying given stations’ diurnal/seasonal variabilities (means, percent frequencies, extremes, etc.)  for various parameters, individually, these represented on single-page grid-layouts analogous to topographic maps. Further graphics’-type additions have been annual time series plots (for example, those of annual mean temperatures or annual total precipitation), cumulative season-to-date totals of precipitation or snowfall, boxplots of calendar-month to calendar-month distributions of some parameter (for example, total precipitation), probability density distribution charts (e.g., those of annual total precipitation) and most recently, analyses and depictions of diurnal mean vector (or “resultant”) wind character, the result of clustering analyses. The selection of parameters, kinds of analyses, and graphics’ types utilized are always subject to  expansion, assuming any new proposed additions are considered novel, worthwhile and interesting.

The charts can be perused by teachers, students, planners, decision makers, and general weather enthusiasts – for some specified purpose(s), or simply for their own sake. The primary focus is visualization, but raw supporting data are usually available upon request.

Charts pertaining to the current year in question are updated on a semi-weekly to semi-monthly basis. Public data sources were (are) utilized to acquire the raw data, with attributions given, and generation of the assorted in climate statistics and creation of their graphical depictions done on an original, “in-house” basis.

As indicated, Climatestations.com at present consists of climatological graphics for ten U.S. stations. Plans are to add yet more stations gradually over time, departing, however, for practical reasons from the sub-format of producing running periodic updates of daily temperatures and precipitation for the present year. Instead, the emphasis will be on climograms, complete year floating bar-charts, and annual time-series plots. The exact mix of these and any additional graphics-types will be determined on a station-by-station basis. Also, for obvious reasons, most of the traffic (>95% – but not all) to Climatestations.com comes from domestic visitors, and plans are also in place to add some foreign stations as well, under the same reduced format.
