NEUBREW NETWORK
REFURBISHMENT AND CALIBRATION

The NEUBrew network instruments are being retrieved form the field for refurbishment, filter change, and Ozone Calibration. The Mark IV Brewers utilize a UG-11/NiSO4 filter combination, which is hygroscopic and sensitive to changes in humidity, and is problematic in the stability of the Brewer Spectroradiometers. Recently, a new type of compatible filter has become available that should have better long-term stability than the UG-11/NiSO4 filter.

During June and July of 2014 Ft Peck, MT; Bondville, IL; Raleigh, NC; and Houston Brewers will be taken off line and transported back to Boulder for refurbishment and ozone calibration by International Ozone Services (IOS). After calibration, all the Brewers will operate in Boulder, CO for some number of weeks to collect ozone measurements for comparison. The Brewers will then be redeployed to their respective field stations later this year.

The NOAA/EPA Brewer Spectrophotometer Network consists of six stations located in the western, central and eastern United States. Brewer instruments provide daily Ultra-Violet (UV) Radiation and Total-Column Ozone measurements. Many Brewers are co-located at NOAA SURFRAD stations equipped with Total Surface Radiation Budget instrumentation, and Total Sky Imagers.
