Atmosphere
Atmospheric variables include temperature, precipitation, wind, pressure, clouds, greenhouse gases, and much more. Overview pages summarize and compare selected datasets of a given variable.
To find a specific dataset or variable, jump to the search box below or click your desired variable from among the blue sub-category buttons. Note that the classification of datasets by variable is approximate, especially for large, multi-variable datasets like reanalyses.
To see only the datasets accompanied by in-depth commentary, select the "Datasets with guidance" button when using the search box.
