Short summary
Long-term trends of total column ozone and assessments of its recovery are underpinned by daily “best representative values” from Brewer spectrophotometers and other ground-based instruments. However, the current calculation of these best representative values often rejects otherwise useful data and has deficiencies during partly cloudy days. We propose a new methodology that takes into account all valid data and accounts for unevenly spaced observations and their uncertainties.
