CMB Experiments

Below is a list of known CMB experiments, with links to their home pages (if available), a brief description, and, whenever possible, links to internal LAMBDA pages which provide the publicly available data from these experiments. LAMBDA serves as a long-term repository for these archives. If an experiment of interest to you is missing from the list, or there is experimental data you would like to provide, please contact us via the suggestion form.

The left-most colum contains links to the individual project websites, which will typically provide the most comprehensive collections of data. The second column contains links to project data held at LAMBDA. Initially the data at LAMBDA might be a subset of the data at the project website, but the LAMBDA holdings will grow with time and they will be maintained as a permanent archive.
