The collection in Kresge primarily consists of climate data sets and materials on atmospheric chemistry and physics. There is a continuing emphasis on collecting materials relating to climate change and climate dynamics. Paleoclimatology, which classes in the QE's as well as in the QC's, is a growing area of interest. Bioclimatology, the influence of climate on plants and animals, are primarily collected in Dana. The influence of climate on humans in terms of agriculture is in Baker and Dana.
Medical climatology is in Dana.
Materials on weather modification and weather forecasting is housed in Kresge. There are materials on the weather of specific geographic areas in Baker, as well as in Kresge. The impacts of cold climate on materials and engineering projects is in Feldberg. Since climate data for many parts of the world is difficult to get, relevant materials will be collected in any language. No geographical area is excluded, but the collection program emphasizes data from North America.
