摘要

One of the tools used by environmentalists, meteorologists, and the media to gauge phenomena such as global or local warming or cooling trends is a particular area's normal temperature, produced by the National Climatic Data Center (NCDC). After quality control algorithms are run, the monthly normal temperatures are calculated as simple 30-yr monthly averages. Daily normals are then derived from the monthly normals using a cubicspline interpolation, a process that produces a smooth data curve (NCDC 2004). The final product, called "daily normal temperature," is a statistically sound number that can be used to examine day-to-day temperature trends.
