Climate Data

The Climate Data Guide is a high-traffic expert knowledge portal providing concise and reliable information on the climate data that are essential for measuring and predicting physical climate risk.

Currently, the Climate Data Guide curates expert insights on over 200 observational datasets and climate indices, searchable or browseable in the list below.

To find a specific dataset or climate variable, jump to the the search box. For only the datasets paired with guidance written by experts, select the "Datasets with guidance" button when using the search box.

Data creators, data publishers, and scientists who use climate data are invited to join our Network of Experts by contributing commentaries on data strengths and limitations to the Climate Data Guide. What type of data are included? See this discussion.

With the exception of about 25 climate indices, the Climate Data Guide does not host datasets.  Data cannot be downloaded from this site. However, links are provided to download locations under the "Data Access" section of each dataset page.
