Abstract: The effect of the width and shape of the New Zealand filter instrument's passbands on measured total ozone accuracy is determined using a numerical model of the spectral measurement process. The model enables the calculation ...

Abstract: A unified statistical approach to identify suitable structural time series models for annual mean temperature is proposed. This includes a generalized model that can represent all the commonly used structural time series ...

Abstract: An analysis of the use of ultraviolet narrow-band interference filters for total ozone determination is given with reference to the New Zealand filter spectrophotometer under the headings of filter monochromaticity, ...

Abstract: Regional climate trends are of interest both for understanding natural climate processes and as tests of anthropogenic climate change signatures. Relative to global trends, however, their detection is hampered by smaller ...
