Cirrus cloud retrieval with MSG/SEVIRI using artificial neural networks [PDF]

Atmospheric Measurement Techniques, 2017
Cirrus clouds play an important role in climate as they tend to warm the Earth–atmosphere system. Nevertheless their physical properties remain one of the largest sources of uncertainty in atmospheric research.

Impacts to the mountain‐valley circulation from the 2023 annular solar eclipse

Weather, EarlyView.
In October 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP), faculty and students from the University of North Dakota (UND) in coordination with Pueblo Community College Southwest collected weather observations during an annular solar eclipse colloquially known as a ‘ring of fire’ eclipse.

High‐frequency gravity waves and homogeneous ice nucleation in tropical tropopause layer cirrus

Geophysical Research Letters, 2016
The impact of high‐frequency gravity waves on homogeneous‐freezing ice nucleation in cold cirrus clouds is examined using parcel model simulations driven by superpressure balloon measurements of temperature variability experienced by air parcels in the ...

Prognostic factors of optical coherence tomography angiography in intermediate and advanced primary open‐angle glaucoma: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Conventional optical coherence tomography (OCT) has a floor effect in patients with severe visual field loss, such as seen in advanced primary open‐angle glaucoma (POAG). OCT angiography (OCTA) does not suffer from such a floor effect. However, which OCTA parameters are most useful for monitoring longitudinal progression is unclear.

Prenatal and childhood exposure to smoking and retinal nerve fibre layer thickness: A meta‐analysis of three independent birth cohorts

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine retinal nerve fibre layer (RNFL) characteristics in relation to prenatal and postnatal smoking exposure in three independent birth cohorts: two Danish and one Australian cohort. Methods A combined meta‐analysis of peripapillary retinal nerve fibre thickness in the Copenhagen Prospective Studies on Asthma in Childhood 2000 ...

Association between metabolic syndrome, macular structures and retinal vascular calibres in the Northern Finland Birth Cohort Eye Study

Acta Ophthalmologica, EarlyView.
Abstract Purpose We aimed to evaluate the association of metabolic syndrome (MetS) with macular thickness and retinal vascular calibres in the population‐based cohort (Northern Finland Birth Cohort). Methods The population of 2242 individuals was divided into MetS (n = 344) and control groups (n = 1898).

High supersaturation inside cirrus in well‐developed tropical tropopause layer over Indonesia

Geophysical Research Letters, 2012
The relationship between relative humidity and cirrus clouds in the tropical tropopause layer (TTL) is investigated using balloon‐borne cryogenic frostpoint hygrometers (CFH) and quasi‐collocated measurements of space‐borne Cloud‐Aerosol Lidar with ...

Properties of Cirrus Clouds over the European Arctic (Ny-Ålesund, Svalbard)

Remote Sensing, 2021
Cirrus is the only cloud type capable of inducing daytime cooling or heating at the top of the atmosphere (TOA) and the sign of its radiative effect highly depends on its optical depth. However, the investigation of its geometrical and optical properties

The effect of rhegmatogenous retinal detachment on retinal oxygenation

Acta Ophthalmologica, EarlyView.
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.
