This map layer has a time line (1945–2017) and, for the selected year, shows the number of nuclear tests carried on by countries on their own soil or on that of other countries above ground, below ground, atmospherically or under water on the real test sites, divided into five categories.
Example of how to read the map:
In 1990, the United States carried out between five and 15 nuclear tests in the test site of Nevada.

CTBTO - Comprehensive Nuclear-Test-Ban Treaty Organization
Founded in 1996 and located in Vienna, CTBTO has made its mission to promote the Treaty and to hamper first development and the further development of nuclear weapons more difficult by operating. A global net of sensors serves as surveillance mechanism; furthermore, it intends to carry out on-site inspections after the Treaty has come into force. The organization can only fulfil its mission completely when the 44 states have ratified Annex 2 of the Treaty; so far, only 41 states have signed, and 36 have ratified the Treaty.

U.S. Department of Energy - Nevada Operations Office
The Atomic Energy Commission that was established in 1947 set up the Nevada Operations Office in 1962 that, after several restructuring efforts, is under the leadership of the National Nuclear Security Administration (NNSA). NNSA maintains and enhances the safety, security, and effectiveness of the US nuclear weapons stockpile without nuclear testing. At the same time, it provides the US Navy with safe and effective nuclear propulsion and responds to nuclear and radiological emergencies in the US and abroad.
