    Analysis of ACAM Data for Trace Gas Retrievals during the 2011 DISCOVER-AQ Campaign by C. Liu, X. Liu, M. G. Kowalewski, S. J. Janz, G. González Abad, K. E. Pickering, K. Chance, L. N. Lamsal

    Published 2015-01-01
    “…From the standard deviations of the fitting residuals, the SNRs of ACAM nadir measurements are estimated to vary from ~300 at 310 nm to ~1000 in the blue spectral region; the zenith data are noisier due to reduced levels of illumination and lower system throughput and also show many more pixels with abrupt anomalous values; therefore, a new method is developed to derive a solar irradiance reference at the top of the atmosphere (TOA) from average nadir measurements, at instrument spectral resolution and including instrument calibration characteristics. …”

    Measuring the Cytochrome c Nitrite Reductase Activity—Practical Considerations on the Enzyme Assays by Célia M. Silveira, Stéphane Besson, Isabel Moura, José J. G. Moura, M. Gabriela Almeida

    Published 2010-01-01
    “…Due to the fast kinetics of ccNiR, electron delivering from reduced electron donors is rate-limiting in all spectrophotometric assays, so the estimated kinetic constants are apparent only. Nevertheless, this limitation could be overcome by using a direct electrochemical approach which shows that the binding affinity for nitrite decreases whilst turnover increases with the reductive driving force.…”
