This paper is aimed at atmospheric scientists without formal training in statistical theory. Its
goal is to (1) provide a critical review of the rationale for trend analysis of the time series …

To date, a large variety of water vapour data records from satellite and reanalysis are
available. It is key to understand the quality and uncertainty of these data records in order to …

Extracting globally representative trend information from lower tropospheric ozone
observations is extremely difficult due to the highly variable distribution and interannual …

Observational records are more often than not influenced by residual non‐climatic factors
which must be detected and adjusted for prior to their usage. In this work, we present a novel …

Climate observations are needed to address a large range of important societal issues
including sea level rise, droughts, floods, extreme heat events, food security, and freshwater …

We have developed a new statistical approach (M 3 Fusion) for combining surface ozone
observations from thousands of monitoring sites around the world with the output from …

Detecting a tropospheric ozone trend from sparsely sampled ozonesonde profiles (typically
once per week) is challenging due to the short-lived anomalies in the time series resulting …

High-quality long-term observational records are essential to ensure appropriate and
reliable trend detection of tropospheric ozone. However, the necessity of maintaining high …

Indicators of large-scale ecological change are typically derived from long-term monitoring
networks. As such, it is important to assess how well monitoring networks provide evidence …

This work focuses on estimating trends in ozone partial pressure, temperature, and water
vapour in the upper troposphere/lower stratosphere (UT/LS) region using a new unified …
