Special Issue Information

Dear Colleagues,

Lidar systems have become a well-established instrumentation deployed around the world, and they also form part of global/regional networks (ACTRIS/EARLINET, NASA MPLNET, LALINET, AD-NET, among others), for characterizing and monitoring both aerosols and clouds with high vertical and time resolution. In particular, lidar systems have been used for research on dust, wild fires, volcanic ashes, and marine aerosols, among other aerosols, as well as on ice clouds; hence, they have contributed to improving investigations with a wide spatio-temporal coverage. In addition, spaceborne lidar instrumentation aboard principal space missions (former NASA CALIPSO, present ESA/JAXA EarthCARE, among others) provides world-wide spatial coverage to complement ground-based lidar networks. Regarding aerosol–cloud interactions (ACIs), both space- and ground-based lidar systems can introduce excellent insights at high vertical and temporal scales. To this Special Issue, we invite the submission of comprehensive analysis of different lidar-based methodologies.

This Special Issue welcomes the submission of studies covering the use of different lidar systems and their lidar-based methodologies to improve our understanding of aerosol and cloud research, including their interactions and atmospheric impact. Topics of interest include climate-relevant aerosol events (dust intrusions, intense forest fires, volcanic eruptions, marine environments, bioaerosols) and cloud occurrence (special emphasis on cirrus clouds), separately, as well as more comprehensive studies on ACIs, including cloud condensation nuclei (CCN) and ice-nucleating particle (INP) issues. Their radiative impact in the atmosphere should also be considered. Hence, multi-platform (satellite, airborne, and ground-based) monitoring studies of aerosols and clouds from lidar observations, in synergy with other instruments, are welcome.

Articles may address, but are not limited to, the following topics:

  • Aerosol optical and microphysical properties;
  • Cloud detection and characterization;
  • CCN and/or INP studies;
  • Aerosol and cloud radiative effects.

This work presents a proof of concept for a short-range high spectral resolution lidar (SR-HSRL) optimized for aerosol characterization in the first kilometer of the atmosphere. The system is based on a compact, high-repetition-rate diode-based fiber laser with a 300 MHz linewidth and 5 ns pulse duration, coupled with an iodine absorption cell. A central challenge in the instrument’s development was identifying a laser source that offered both sufficient spectral resolution for HSRL retrievals and nanosecond pulse durations for high spatiotemporal resolution, while also being compact, tunable, and cost-effective. To address this, we developed a methodology for complete spectral and temporal laser characterization. A two-day field campaign conducted in July 2024 in Tsukuba, Japan, validated the system’s performance. Despite the relatively broad laser linewidth, we successfully retrieved aerosol backscatter coefficient profiles from 50 to 1000 m, with a spatial resolution of 7.5 m and a temporal resolution of 6 s. The results demonstrate the feasibility of using SR-HSRL for detailed studies of aerosol layers, cloud interfaces, and aerosol–cloud interactions. Future developments will focus on extending the technique to ultra-short-range applications (<100 m) from ground-based and mobile platforms, to retrieve aerosol extinction coefficients and lidar ratios to improve the characterization of near-source aerosol properties and their radiative impacts.
