IRI/LDEO Climate Data Library is one of 10 APIs that [Columbia University](https://apis.io/providers/columbia/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Research Computing, Climate Data, OPeNDAP, WMS, and Earth Science. The published artifact set on APIs.io includes API documentation.

The Climate Data Library run by the International Research Institute for Climate and Society and the Lamont-Doherty Earth Observatory, both Columbia University units. A long-running research-computing surface with its own URL-based dataset query language, OPeNDAP access and OGC WMS output, and historically one of the more genuinely programmable things any university operated. It is recorded here with a material access change: the landing pages still return 200, but every data path probed — /SOURCES/, the OPeNDAP endpoints and a WMS GetCapabilities request — now redirects to /auth/login. Presence without access, announced nowhere machine-readable.
