Provisional Data Notice

It is the intent of the CEMP to provide to the public accurate, near real-time monitoring data through this web site. However, it should be noted that these data are provisional and therefore may be subject to change. Provisional data may be adjusted for various reasons including disruption of sensors, instrument calibration, equipment failure, and problems with data transfer. These data are not valid until thoroughly reviewed and evaluated by the Desert Research Institute. Data users are cautioned to carefully consider the provisional nature of this information before any application, particularly for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these provisional data may be obtained by contacting the Western Regional Climate Center at wrcc@dri.edu or by calling (775) 674-7010.

Data Collection Program

The Community Environmental Monitoring Program (CEMP) is a network of 29 monitoring stations located in communities surrounding and downwind of the Nevada National Security Site (NNSS), formerly the Nevada Test Site (NTS), that monitor the airborne environment for manmade radioactivity that could result from NNSS activities. The CEMP is a joint effort between the Department of Energy's National Nuclear Security Administration Nevada Site Office (NNSA/NSO), and the Desert Research Institute (DRI) of the Nevada System of Higher Education.
