Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Deep tropical oceanic convection is a key component of the tropical atmosphere, with environmental moisture and vertical wind shear influencing its structure and intensity. However, attempts to generalize convection‐environment relationships across the broad‐scale tropics have produced inconsistent results, partly owing to limits of reanalysis,

Evaluation of a Decade of Methane Observations From a Tower Network in Indianapolis, Indiana
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Methane (CH4) is a critical near‐term climate mitigation target, yet urban sources remain poorly constrained. Indianapolis hosts one of the world's longest and densest urban CH4 data sets, with continuous measurements from a tall‐tower network spanning more than a decade.

Coherent Focused Lidars for Doppler Sensing of Aerosols and Wind [PDF]
Remote Sensing, 2018 Many coherent lidars are used today with aerosol targets for detailed studies of e.g., local wind speed and turbulence. Fibre-optic lidars operating near 1.5 μm dominate the wind energy market, with hundreds now installed worldwide. Here, we review some of the beam/target physics for these lidars and discuss practical problems.

Real Time Turbulence Estimation Using Doppler Lidar Measurements
EPJ Web of Conferences, 2016 A preliminary work on a new way to estimate atmospheric turbulence using high-frequency Doppler lidar measurements is presented. The turbulence estimations are based on wind reconstruction using 3D Doppler lidar observations and a particle filter.
