The NCDC says:

Evidence is mounting that global climate is changing. The extent to which man is responsible is still under study. Regardless of the causes, it is essential that a baseline of long-term climate data be compiled; therefore, global data must be acquired, quality controlled, and archived.

, NCDC develops standards by which data can be exchanged and made accessible.



NCDC provides the historical perspective on climate. Through the use of over a hundred years of weather observations, reference data bases are generated. From this knowledge the clientele of NCDC can learn from the past to prepare for a better tomorrow. Wise use of our most valuable natural resource, climate, is the goal of climate researchers, state and regional climate centers, business, and commerce.
