Spatial Heterogeneity and Inhomogeneity of Cirrus Microphysical Properties on Kilometer Spatial Scales

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Previous studies reporting the spatial inhomogeneity and heterogeneity of cirrus cloud properties have primarily been case studies derived from relatively small data sets. This study evaluates the spatial heterogeneity and inhomogeneity of cirrus bulk microphysical properties using ∼60 hr of in situ measurements from eight field campaigns. The

Height of Cirrus Cloud [PDF]

Nature, 1872
IT would be interesting if any of the readers of NATURE could give some information respecting the usual height of cirrus clouds. Mr. Clement Ley, in his work, “The Laws of the Winds,” states—“The time occupied by these clouds in passing from the zenith to 45°, or the contrary, furnishes us with a standard of measurement which is both convenient for ...

Universality in snowflake aggregation [PDF]

, 2004
Aggregation of ice crystals is a key process governing precipitation. Individual ice crystals exhibit considerable diversity of shape, and a wide range of physical processes could influence their aggregation; despite this we show that a simple computer ...

Geometrical and optical properties of cirrus clouds in Barcelona, Spain: analysis with the two-way transmittance method of 4 years of lidar measurements [PDF]

Atmospheric Measurement Techniques
In this paper a statistical study of cirrus geometrical and optical properties based on 4 years of continuous ground-based lidar measurements with the Barcelona (Spain) Micro Pulse Lidar (MPL) is analysed. First, a review of the literature on the two-way

Comparing airborne and satellite retrievals of cloud optical thickness and particle effective radius using a spectral radiance ratio technique: two case studies for cirrus and deep convective clouds [PDF]

Atmospheric Chemistry and Physics, 2018
Solar radiation reflected by cirrus and deep convective clouds (DCCs) was measured by the Spectral Modular Airborne Radiation Measurement System (SMART) installed on the German High Altitude and Long Range Research Aircraft (HALO) during the Mid ...

Retrieval of rice biophysical parameters from Sentinel‑2 using parsimonious multi‑output machine learning

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Rice (Oryza sativa L.) crop monitoring in Africa requires efficient retrieval of biophysical parameters such as leaf area index (LAI) and leaf chlorophyll content (LCC), which are essential for crop stress detection and nutrient management.

Intercomparison of multiple years of MODIS, MISR and radar cloud-top heights

, 2005
International audienceRadar cloud-top heights were retrieved at both the Chilbolton Facility for Atmospheric and Radio Research, UK (CFARR) and the ARM Southern Great Plain site, USA (SGP), using millimetre wave cloud radars and identical algorithms. The

Intercomparison of CL31 and CL51 ceilometers and impact of installation angle on cloud base height measurement agreement

Weather, Volume 81, Issue 6, Page 191-199, June 2026.
Lowest‐layer cloud base height (CBH) measurements obtained between July 2018 and December 2019 from four ceilometers at the Korea Standard Meteorological Observatory were compared to determine how ceilometer installation angle differentially affects CBH measurements.

Active Imaging through Cirrus Clouds

Optics Express, 1997
The presence of clouds of ice particles in the uplink and downlink path of an illumination beam can severely impede the performance of an active imaging system. Depending on the optical depth of the cloud, i.e., its density and depth, the beam can be completely scattered and extinguished, or the beam can pass through the cloud with some fraction ...

Evaluating the Biases in Indian Summer Monsoon Rainfall Simulation Using the Global Storm Resolving Models: An Assessment of the DYAMOND Models

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study evaluated the performance of various global storm‐resolving models (GSRMs) in simulating the Indian Summer Monsoon (ISM), highlighting the limitations of current global kilometer‐scale models in accurately representing precipitation patterns over the Indian subcontinent.
