Temperature dependence of the Brewer ultraviolet data

Abstract: Abstract. We characterize the temperature dependence of the U.S. Environmental Protection Agency/University of Georgia network of Brewer spectrophotometers as used to measure solar ultraviolet (UV) radiation. The instruments used in this study are operated in partnership with the National Park Service at 14 national park sites and in 7 urban areas. The daily and seasonal measurements of UV radiation provided by the instruments can be affected by changes in the internal instrument temperatures at the sites. The… Show more

“…These measurements are corrected regularly for the effects from changes in temperature, but, because the ozone algorithms are based on radiance ratios, temperature related changes to the instrument response are not critical, as long as the changes are independent of wavelength (Weatherhead et al, 2001). However, in the spectral irradiance measurements the temperature sensitivity of the Brewer is expected to be more apparent.…”

“…The advantage of this method is that it provides a lot of information on the history of the temperature coefficients, which appear to vary with time. The main disadvantage is the lack of information on possible temperature effects on the operation of the internal standard lamps, including the electronic circuit that drives these lamps (Weatherhead et al, 2001).…”

“…8(a) to 8(b) [27]. They also correct for the temperature dependence of the responsivity that typically is 0.4 -0.1%/°C [28,29]. However, the temperature difference between the two responsivity measurements is only 0.1°C and this cannot explain the difference observed from Fig.…”

“…The stability of the lamps used for the CUCF calibration are given in section 4 and are less than 1% during the intercomparison. Other uncertainties include the temperature dependency in the responsivity and the correction of the data [28]; recent studies have looked at the temperature dependence of PTFE diffusers [32,33]. Uncertainties in spectral solar irradiance from well-maintained spectroradiometers have been estimated at ±6.3% -12.7% from the UVA to 300 nm [23].…”
