Climate History Network

The National Center for Atmospheric Research (NCAR) has launched a tool for searching and evaluating climate data sets.  NCAR explains the Climate Data Guide as “the go-to source for scientifically sound information and advice on the strengths, limitations, and applications of climate data. Experts who construct, evaluate, and compare climate data sets contribute their perspectives and advice on climate data and analysis methods for a broad community of data users. Users may participate by posting comments, questions, and links.”  For now, there are only a few datasets going back more than a century, so it has limited use for historians.  However, the searchability and clear evaluations of data make it a valuable tool for non-specialists.  (The link has been added to the “Databases and Projects” page.)
