Have students compute the difference in min and max records in % to show differences more dramatically.
The daily records summarized in the tool are compiled from a subset of stations in the Global Historical Climatological Network. A station is defined as the complete daily weather records at a particular location, having a unique identifier in the GHCN-Daily dataset. For a station to be considered for any parameter, it must have a minimum of 30 years of data with more than 182 days complete each year. This is effectively a "30-year record of service" requirement but allows for inclusion of some stations which routinely shut down during certain seasons. Comments from expert scientist: Scientific strengths: - analyzing raw data - explanation of what constitutes a science 'station' - could use this data to plot graphs, make figures, make interpretations Suggestions: - If high max/min and low max/min is referring to temperature, might want to add that in.
Simple, straightforward,and updated daily. This tool provides simple counts of weather records to provide insight into recent climate behavior. Although not a definitive way to identify trends in the number of records set over time, trends over a year's time are interesting and informative when comparing high and low max and min temperatures nationally. Data is split into daily, monthly, and all-time records.
