Cloud‐Rain Vertical Inconsistency Increases IMERG Precipitation Uncertainty

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract IMERG accuracy is limited by the vertical inconsistency between satellite‐observed cloud‐top information and the true vertical structure of precipitation. Using FY‐3G Precipitation Measurement Radar (PMR) observations as reference and FY‐4B cloud‐top parameters, we investigate the vertical‐structure sources of IMERG retrieval errors during the

An Optimized Parameterization of Sub‐Grid Scale Advection for Convection Permitting Models

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Convection‐permitting models (CPMs) explicitly resolve deep convection yet under‐resolve the organized lateral exchanges among drafts and their environment that control entrainment/detrainment, precipitation efficiency, and mesoscale structure.

Water in cirrus clouds

Eos, Transactions American Geophysical Union, 1984
Meteorologists from the University of Utah have discovered water droplets as cold as −36°C at the base of cirrus clouds, the coldest temperatures at which liquid water has been confirmed in clouds. Because earlier models of radiation transfer in the atmosphere had assumed that the clouds at cirrus‐layer altitudes (6,000–12,000 m) were composed only of ...

Nitric acid in cirrus clouds

Geophysical Research Letters, 2006
Uptake of nitric acid (HNO3) in Arctic cirrus ice crystals was observed on 11 February 2003 by in‐situ instruments onboard the M55 Geophysica aircraft. The cirrus cloud with a mean ice water content of 5.4 mg m−3 covered northern Scandinavia for several hours and extended up to the thermal tropopause at 12.3 km.

Cirrus Detection Based on RPCA and Fractal Dictionary Learning in Infrared imagery

Remote Sensing, 2020
In earth observation systems, especially in the detection of small and weak targets, the detection and recognition of long-distance infrared targets plays a vital role in the military and civil fields.

Dust Decline Amplifies High‐Cloud Ice‐to‐Liquid Transition and Buffers the Radiative Feedback Under Warming

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The response of the cloud phase to global warming is a critical yet poorly constrained component of Earth's climate sensitivity. While rising temperatures drive a thermodynamic transition from ice to liquid clouds, the role of ice‐nucleating particles in modulating this shift remains underexplored.

Understanding the polarization signal of spherical particles for microwave limb radiances

, 2006
This paper presents a simple conceptual model to explain that even spherical scatterers lead to a polarization difference signal for microwave limb radiances.

Contrail and Cirrus Observations over Europe from 6 Years of NOAA-AVHRR Data

, 2002
Thin ice clouds – cirrus and contrails – are analysed in a long-term 1 km data set from the Advanced Very High Resolution Radiometer (AVHRR). Here twice daily data received at DLR Oberpfaffenhofen covering most of Europe over the full lifetime of the ...

Changes in cirrus cloudiness and their relationship to contrails

, 2001
Condensation trails, or contrails, formed in the wake of high-altitude aircraft have long been suspected of causing the formation of additional cirrus cloud cover.
