Short summary
We statistically analyze the hygroscopic growth characteristics of urban anthropogenic aerosols over Wuhan, a megacity over central China, using lidar observations and Hänel parameterization from 2010 to 2024. Aerosol hygroscopic parameter γ increases from 2014 to 2017 and stabilizes at high levels afterwards, aligning with the changes in NO2-to-SO2 concentration ratio. Moreover, no evident differences are found across seasons, as well as between the free troposphere and boundary layer.

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.

With space-borne lidar and radar observations, we study two dust-cirrus interaction cases near Midway Island in the central Pacific. Partial cloud parcels show evident feature of the dominance of heterogeneous nucleation. At the upper troposphere, natural INPs such as dust and smoke may result in cooling effect by increasing the cloud cover to reflect more solar radiation and modulate the cirrus microphysical properties via different ice-nucleating regimes.

With the AERONET database, this study derives dust-related conversion factors at oceanic sites used in the POLIPHON method, which can convert lidar-retrieved dust extinction to ice-nucleating particle (INP)- and cloud condensation nuclei (CCN)-relevant parameters. The particle linear depolarization ratio in the AERONET aerosol inversion product is used to identify dust data points. The derived conversion factors can be applied to inverse 3-D global distributions of dust-related INPCs and CCNCs.

We study the characteristics of the boundary layer over three areas: the tropical Atlantic, the tropical West African continent, and near Cabo Verde using PollyXT and CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) lidar measurements, as well as ECMWF (European Centre for Medium-Range Weather Forecasts) data. The findings underline the strengths and limitations of different observational and modeling approaches, and emphasizes on the importance of considering aerosol conditions and local meteorology when interpreting boundary layer dynamics.

We present a global dataset of POlarization LIdar PHOtometer Networking (POLIPHON) dust conversion factors at 532 nm obtained using Aerosol RObotic NETwork (AERONET) observations at 137 sites for ice-nucleating particle (INP) and 123 sites for cloud condensation nucleation (CCN) calculations. We also conduct a comparison of dust CCN concentration profiles derived using both POLIPHON and the independent Optical Modelling of the CALIPSO Aerosol Microphysics (OMCAM) retrieval.

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.

This study introduces a novel method to detect horizontally oriented ice crystals (HOICs) using two ground-based polarization lidars at different zenith angles, based on a yearlong dataset collected in Beijing. Combined with cloud radar and reanalysis data, the fine categorization results reveal HOICs occur in calm winds and moderately cold temperatures and are influenced by turbulence near cloud bases. The results enhance our understanding of cloud processes and improve atmospheric models.

Short summary
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 report the lidar inter-comparison results with a reference lidar at 1064 nm, in order to homogenize the signals provided by different lidar systems for establishing a lidar network in China. The profiles of relative deviation of lidar signals are less than 5 % within 500–2000 m and 10 % within 2000–5000 m, increasing confidence in the reliability of the signals provided by each lidar system in the channels at 1064 nm for a future lidar network in China.

DeLiAn is a collection of lidar-derived aerosol intensive optical properties for several aerosol types, namely the particle linear depolarization ratio, the extinction-to-backscatter ratio (lidar ratio) and the Ångström exponent. The data collection is based on globally distributed, long-term, ground-based, multiwavelength, Raman and polarization lidar measurements and currently covers two wavelengths, 355 and 532 nm, for 13 aerosol categories ranging from basic aerosol types to mixtures.

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.

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.

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.

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.

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.

Part 2 presents the application of the dual-FOV polarization lidar technique introduced in Part 1. A lidar system was upgraded with a second polarization telescope, and it was deployed at the southernmost tip of South America. A comparison with alternative remote sensing techniques and the evaluation of the aerosol–cloud–wind relation in a convective boundary layer in pristine marine conditions are presented in two case studies, demonstrating the potential of the approach for ACI studies.

Short summary
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, since 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 the evolution of tropospheric aerosols over Wuhan, central China, from 2010 to 2024....
