This product displays daily climate data for a location in a calendar format. For each day, the folowing data are displayed: Normal maximum temperature, normal minimum temperature, normal daily heating and cooling degree days, normal daily precipitation, record maximum temperature, record minimum temperature, and record daily precipitation. The calendar is in a "perpetual format", that is, a specific date is not tied to a day of the week.
In addition to the daily data, monthly statistics for the location are included (normal and extreme temperature, precipitation and snowfall). Some locations may not collect temperature or snowfall data. If that is the case, those fields are blank on the calendar.
Normal values are from the 1981-2010 normals published by the National Climatic Data Center (NCDC). Record values at each station are for the period of record which is noted in the upper right of the calendar. Data is not always complete for this period and completeness can vary among elements.
