Ultraviolet and Ozone Monitoring Program: NEUBrew

The NOAA-EPA Brewer Spectrophotometer UV and Ozone Monitoring Network (NEUBrew) is a collaborative effort between EPAs Office of Air Quality, Planning and Standards and NOAAs Earth System Research Laboratory (ESRL).

NEUBrew is comprised of six stations located across the U.S. that measure solar spectral UV irradiance and total column ozone. Several products are derived from these measurements and are available online to the research community. Future NEUBrew products will include ozone profiles, tropospheric ozone, total column abundance of NO2 and SO2, and UV aerosol optical depths. Program description, data and web-based tools are available from August 2006 to present and may be obtained by visiting the NEUBrew website.


EPA's Previous Ultraviolet Monitoring Program: UV-Net

From the mid-1990s until 2004, EPAs UV-Net Program operated a network of Brewer spectrophotometers throughout the United States. This website provides information about the EPAs UV-Net Program and access to the data collected up to 2003-2004.

The EPA UV-Net Program utilized a network of Brewer spectrophotometers throughout the United States to measure full-sky spectrally resolved solar radiation in the UV-B and UV-A bands. Irradiance and total column ozone concentrations were derived from the data. The data were analyzed and stored in a data base for dissemination to government and non-government scientists and interested parties.

Fourteen of the UV monitoring sites were located in National Parks and were operated by National Park Service employees as part of the Park Research and Intensive Monitoring of Ecosystems Network (PRIMENet Exit EPA Disclaimer). An additional set of seven sites were operate in urban areas. The UV monitoring under this program is coordinated with measurement programs of other U.S. Federal agencies through the U.S. Global Change Research Program.

Specifically this program:

Provides information on the geographical distribution and temporal trends of Ultraviolet radiation in the United States;

Provides long-term records of UV irradiance to scientists studying effects of UV on biota and materials.
