NCEI's land-based (in situ) datasets are developed from data collected across the United States and globally.Data availability varies by data type and station, and some have periods of record of more than a century. If you check the box to "Include base temperatures nearby", Degree Days.net will calculate your degree days to a range of base temperatures around the one that you specify. (For cooling degree days, the process works in reverse: the base temperature is subtracted from the average, and if this value is positive, that number represents the CDD.) We use sophisticated processes to identify and discard erroneous temperature readings and to fill in gaps with interpolated data. A high number of degree days generally results in higher levels of energy use for space heating or cooling. We calculate degree days using sophisticated methods that take into account the temperature variations within each day. HDD are often calculated using simple approximation methods that use daily temperature readings instead of more detailed temperature records such as half-hourly readings, the latter of which can be used to estimate an integral. Degree Days.net is not unique in having to deal with less-than-perfect temperature data, as the vast majority of real-world weather stations are less than perfect in some shape or form. Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. Do make sure to use your own judgment when selecting whether or not to use data from any particular station - only you can determine the level of accuracy that you require. Figures based on estimated data are marked with a "% estimated" value so you can see where the detected problems lie.
