New Version of Climate Data Online Released

Climate Data Online Version 3.0 Screen Capture

Climate Data Online 3.0 is available from the NCDC website at

In July 2013, NCDC released a new version of its Climate Data Online (CDO) system–version 3.0. CDO 3.0 provides access to new datasets and a completely new look and feel to the system. The CDO interface now provides access to 11 datasets, each with multiple output products, in addition to supporting access to 14 legacy systems. Users can access all of these datasets as well as Climate Data Record products through the CDO interactive mapping tool. For the first time, access to Level II and Level III radar data is available through CDO, allowing multiple radar products to be ordered in a single request.

The CDO Search Tool now provides more visual feedback for any given request. The interactive map displayed allows users to modify their requests for data and areas of interest. The Search Tool also now includes 2,400 major cities and metropolitan areas worldwide. Each city’s extent is defined by a population-weighted scheme, and the Station Details page provides additional station and equipment history using NCDC’s station metadata system, Historical Observing Metadata Repository.

All of these updates pave the way for more enhanced access to NCDC’s data holdings and provide a richer user experience.
