NCDC is releasing a new version of the Climate Data Online (CDO) application—version 3.1. This new version of CDO includes an updated look and feel as well as several new features. One of the most prominent new features is the new Data Tools section, which provides alternative methods for accessing some of the data available through CDO.

The Data Tools section includes specialized tools for accessing 1981–2010 U.S. Climate Normals and Daily Weather Records. The Climate Normals tool provides temperature and precipitation Normals for over 9,800 stations across the United States along with a graphical representation. The Daily Weather Records tool provides access to summaries of recent global and U.S. daily weather records, including high daily maximum and minimum temperatures, low daily maximum and minimum temperatures, precipitation, snowfall, and snow depth.

Focusing on simple approaches to access, the CDO Data Tools section also includes Find a Station and Select a Location options. The Find a Station tool allows you to locate specific weather observing stations using a variety of parameters such as address, ZIP, date, and data type. While the Select a Location tool allows you to order data by weather observing stations or by geographic locations using a simplified interface.

As part of the new design, the main page for the CDO application now prominently highlights different sections of the site for easy access to the datasets, help, certification, and order status parts of the system. Web services to improve capacity and throughput are also now available to users. Improved system-to-system communication of climate data for clients who have developed specialized access modules will enable those users to access more data with fewer requests.

The interactive GIS Mapping Tool that is part of the CDO application has also been updated and now includes the ability to display historical maps of average, maximum, and minimum temperatures as well as snowfall and snow depth observations. Radar data have been moved into the Mapping Tool as an individual theme with an option to display station coverage. A new set of left-hand navigation tools, which is more concise and reduces clutter, is also available in the updated version of the mapping application. The Mapping Tool also now supports dynamic resizing of station symbols and an updated map selection tool.
