NOAA Climate Change Data and Detection

The Climate Change Data and Detection (CCDD) program ensures that the data needed to understand the climate system is available for analysis. The data and resulting products extend the existing long-term climate record and serve as essential input to predictive models. In addition, CCDD provides support for documenting variations in climate on time scales ranging from less than one year to periods of 100 years and longer. Support is also provided for the analysis of observed climate variations and changes to identify causes that are consistent with Earth's long-term climate history.
