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

Climatestations.com was originally created to present graphically (floating-bar charts) on a year-to-year basis, the remarkably lengthy and 99.6 percent intact daily maximum/minimum temperature history for Minneapolis-St. Paul MN, dating back to 1820, now 200 years.  Also included, subject to the archival availability for MSP, were depictions of daily precipitation, snowfall, and snow depth observations.

From this start, nine additional stations, most with climatic histories approaching or exceeding a century in length have been added over time (New York Central Park, Chicago, Los Angeles, San Francisco, San Diego, 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.  With so much data from so many stations being presented, the focus is necessarily visual, and the goal is to construct the individual-year visualizations, as well as others (described below), to be interesting and informative from a physical interpretative standpoint, and perhaps most importantly, visually appealing from a pure pattern one.  For example, for typical calendar years, the floating-bar temperature patterns for Los Angeles, Miami, San Francisco, and New York in particular, differ noticeably from each other on a pure pattern basis   

Other climate variables, such as wind (mean vector, mean scalar; extremes) and 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, 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, probability density distribution charts (e.g., those of annual total precipitation) and, analyses and depictions of diurnal mean vector (or “resultant”) wind character modes, a 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. As mentioned above, 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 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.

Also, for obvious reasons, most of the traffic (>99% – but not all) to Climatestations.com comes from domestic visitors, and plans are also in place to add a few foreign stations as well (for example, Helsinki, Finland), under a reduced format.
