A 3D Model of Ryegrass Shoot Architecture, Sward Light Interception and Photosynthesis

New Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
Increasing the photosynthetic capacity of perennial ryegrass (Lolium perenne L.) is required to improve the productivity of pastoral farming in temperate regions. A three‐dimensional (3D) model was constructed of the shoot growth of ryegrass based on plant morphological traits such as tiller angle, leaf angle, leaf width, number of tillers per plant ...

Influence of Model Resolution on Simulated Extreme Wildfire Plume Heights During the 2019/2020 Australian New Year Event

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Pyrocumulonimbus (pyroCb) events, smoke‐infused thunderstorm clouds triggered by intense wildfires under suitable meteorological conditions, are an efficient pathway for transporting smoke to elevated altitudes. In some cases, smoke reaches the upper troposphere and lower stratosphere region, where it can persist for extended time periods and ...

Global Characterization of Stratospheric Sulfate Aerosols by the Atmospheric Chemistry Experiment (ACE)

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Stratospheric sulfate aerosol (SSA) is an important part of the Earth's climate system. SSA climate impact is determined in part by particle composition, which has been measured from orbit. The weight percent of sulfuric acid in SSA has been determined from atmospheric infrared transmittance spectra recorded with the Atmospheric Chemistry ...

Trends and Sensitivities of Low‐Cloud Cover and Top Height From Spaceborne Lidar Observations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low clouds effectively cool the Earth by reflecting incoming solar radiation. Detecting low‐level clouds with passive satellite sensors can be ambiguous, whereas active remote sensing instruments directly measure cloud‐top height. Here, we analyze 14 years of spaceborne lidar observations to assess trends in the occurrence of low‐level clouds ...

Measurements of Water Vapor Profiles with Compact DIAL in the Tokyo Metropolitan Area

EPJ Web of Conferences, 2018
In recent years, the frequency of occurrence of locally heavy rainfall that can cause extensive damages, has been increasing in Japan. For early prediction of heavy rainfall, it is useful to measure the water vapor vertical distribution upwind cumulus ...
