The WFCAM Science Archive (WSA) holds the image and catalogue data products generated by the Wide Field Camera (WFCAM) on UKIRT. The primary contents of the archive will originate from the UKIRT InfraRed Deep Sky Surveys (UKIDSS): Large Area Survey, Galactic Plane Survey, Galactic Clusters Survey, Deep Extragalactic Survey and the Ultra Deep Survey.

Survey data are being released in phases, firstly to the UKIDSS community and then to the public (see data policy).

A DR11 release has been made of UDS data, the database name is called UKIDSSDR11PLUSUDSONLY, note this release does not contain data from the other surveys.

The latest all survey UKIDSS release is UKIDSS data release 10 (UKIDSSDR10PLUS) and includes data up to semester 11B.
The latest WORLD release is UKIDSS data release 10 (UKIDSSDR10PLUS).
