Short summary
Tropopause height is a key climate change indicator, with accurate long-term trends vital for climate research. Radiosonde data, while reliable, has limited coverage. ERA5 is a reanalysis dataset that provides global data, enabling comparisons of tropopause height estimates and then analyzed for long-term trends. Results show a 32 m mean difference (radiosonde – ERA5) with trends of +5 m/year (radiosonde) and +3 m/year (ERA5), crucial for characterizing tropopause changes under climate change.

We present a global data set of POLIPHON dust conversion factors at 532 nm obtained using Aerosol RObotic NETwork (AERONET) observations at 137 sites for INP and 123 sites for CCN calculations. We also conduct a comparison of dust CCN concentration profiles derived using both POLIPHON and the independent OMCAM (Optical Modelling of the CALIPSO Aerosol Microphysics) retrieval.

We usually believe that the impact of magnetic storms will not reach the mesosphere. However, in the storm on 4 Nov. 2021, the mesospheric metal layer depletion was recorded by three lidars for different metal components at mid-latitudes. The storm induced oxygen density enhancement is considered to consume more metal atoms in the metal layer. It implies that the effects of storm have reached mesosphere, and the influence of storm on metal layer is achieved through chemical processes.

The height of the convective boundary layer (CBLH) is related to our health due to its crucial role in pollutant dispersion. The variance of vertical velocity from millimeter wave cloud radar (MMCR) can accurately capture the diurnal evolution of the CBLH, due to a small blind range and less impact by the residual layer. The CBLH is affected by radiation, humidity, cloud, and precipitation; thus, the MMCR is suitable for monitoring the CBLH, owing to its observation capability in various weather conditions.

The most commonly used tropopause height detection algorithm is based on the World Meteorological Organization (WMO) definition from 1957. However, with the increasing vertical resolution of atmospheric data, this definition has been found to fail in high-resolution radiosonde data. Thus, we propose an improved method to address this issue. This method can effectively bypassing thin inversions while preserving the fine–scale structure of the tropopause.

We present the evolution of tropospheric aerosols over Wuhan, central China, from 2010 to 2024. The analysis highlights the long-term aerosol characteristics and separates natural (dust) and anthropogenic (non-dust) contributions. Emission control policies were highly effective during 2010–2017. However, after 2018, lidar-derived aerosol optical depth (AOD) ceased decreasing and fluctuated, and the decline in PM2.5 concentration also became slower, possibly due to atmospheric chemistry factors.

We present a long-term ground-based lidar observation of stratospheric aerosols at a mid-latitude site, Wuhan, in central China, from 2010 to 2021. We observed a stratospheric background period from 2013 to mid-2017, along with several perturbations from volcanic aerosols and wildfire-induced smoke. In summer, injected stratospheric aerosols are found to be captured by the Asian monsoon anticyclone, resulting in prolonged residence and regional transport in the mid-latitudes of East Asia.

We discuss several robust estimators to compute the variance of a normally distributed random variable to deal with interference. Compared to rank-based estimators, the methods based on the geometric mean are more accurate and are computationally more efficient. We apply three robust estimators to incoherent scatter power and velocity processing, along with the traditional sample mean estimator. The best estimator is a hybrid estimator that combines the sample mean and a robust estimator.

Short summary
Kelvin–Helmholtz instability (KHI) is indicated by the critical value of the Richardson (Ri) number, which is usually predicted to be 1/4. Compared to high-resolution radiosondes, the threshold value of Ri could be approximated as 1 rather than 1/4 when using ERA5-based Ri as a proxy for KHI. The occurrence frequency of subcritical Ri exhibits significant seasonal cycles over all climate zones and is closely associated with gravity waves and background flows.

We present a novel method to measure the amplitudes of traveling quasi-5-day oscillations (Q5DOs) in the middle atmosphere during sudden stratospheric warming events based on satellite observations. Simulations and observations demonstrate that the previously reported traveling Q5DOs might be contaminated by stationary planetary waves (SPWs). The new fitting method is developed by inhibiting the effect of a rapid and large change in SPWs.

A method is proposed to identify the sole presence of heterogeneous nucleation and competition between heterogeneous and homogeneous nucleation for dust-related cirrus clouds by characterizing the relationship between dust ice-nucleating particle concentration calculated from CALIOP using the POLIPHON method and in-cloud ice crystal number concentration from the DARDAR-Nice dataset. Two typical cirrus cases are shown as a demonstration, and the proposed method can be extended to a global scale.

Short summary
Using radar observations and reanalysis data for 9 years, we demonstrate clearly for the first time that resonant interactions between tides and annual and semiannual oscillations do occur in the mesosphere and lower thermosphere. The resonant matching conditions of frequency and wavenumber are exactly satisfied for the interacting triad. At some altitudes, the secondary waves are stronger than the tides, thus in tidal studies, the secondary waves may be mistaken for the tides if no carefully.

Our lidar observations reveal the complete microphysical process of hydrometeors falling from mid-level stratiform clouds. We find that the surface rainfall begins as supercooled mixed-phase hydrometeors fall out of a liquid parent cloud base. We find also that the collision–coalescence growth of precipitating raindrops and subsequent spontaneous breakup always occur around 0.6 km altitude during surface rainfalls. Our findings provide new insights into stratiform precipitation formation.

Short summary
The planetary boundary layer (PBL) is the lowest part of the troposphere, and boundary layer height (BLH) is the depth of the PBL and is of critical importance to the dispersion of air pollution. The study presents the first near-global BLH climatology by using high-resolution (5-10 m) radiosonde measurements. The variations in BLH exhibit large spatial and temporal dependence, with a peak at 17:00 local solar time. The most promising reanalysis product is ERA-5 in terms of modeling BLH.

The POLIPHON method can retrieve the height profiles of dust-related particle mass and ice-nucleating particle (INP) concentrations. Applying a dust case data set screening scheme based on the lidar-derived depolarization ratio (rather than Ångström exponent for 440–870 nm and AOD at 532 nm), the mixed-dust-related conversion factors are retrieved from sun photometer observations over Wuhan, China. This method may potentially be extended to regions influenced by mixed dust.

Using high-resolution lidar measurements, this process-based study reveals that the clear-day convective boundary layer evolves in four distinct stages differing in depth growth rate and depth fluctuation magnitudes. The accompanying entrainment zone thickness (EZT) shows a discrepancy in statistical mean and standard deviation for different seasons and developing stages. Common EZT characteristics also exist. These findings help us understand the atmospheric boundary layer evolution.

Short summary
El Niño has an important influence on climate systems. There are obviously negative water vapor anomalies from radiosonde observations in the tropical western Pacific during El Niño. The tropical Hadley, Walker, and monsoon circulation variations are revealed to play different roles in the observed water vapor anomaly in different types of El Niños. The Walker (monsoon) circulation anomaly made a major contribution in the 2015/16 (2009/10) strong eastern Pacific (central Pacific) El Niño event.
