Climate Mirror

Climate Mirror is "an open project to mirror public climate datasets", that is, an open access project to mirror (to back up) the data of publicly owned datasets from climate science, such as data from U.S. federally funded research. Datasets from the National Oceanic and Atmospheric Administration (NOAA), the Environmental Protection Agency (EPA), and NASA are considered primary examples.
The idea behind Climate Mirror is comparable to the notion that lots of copies keep stuff safe from disappearing through censorship, link rot, lapses of professionalism in preserving the integrity of the scientific record, or lack of digital permanence. It offers a parallel type of massive backup.
