Feasibility of using Nanofiltration membranes to delay Reverse Osmosis membrane fouling and to reduce energy consumption (BWC desalination plant) [PDF]

open access: yesJournal of Water and Environmental Nanotechnology, 2023
The Beni Saf Water Company (BWC) desalination plant in Ain Témouchent (Algeria) uses reverse osmosis technique. This process, which is based on dense membranes operating at high pressure, produces a permeate with characteristics that exceeds the ...

Identification of snowfall microphysical processes from Eulerian vertical gradients of polarimetric radar variables [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Polarimetric radar systems are commonly used to study the microphysics of precipitation. While they offer continuous measurements with a large spatial coverage, retrieving information about the microphysical processes that govern the evolution of ...

A characterisation of Alpine mesocyclone occurrence [PDF]

open access: yesWeather and Climate Dynamics, 2021
This work presents a characterisation of mesocyclone occurrence and frequency in the Alpine region, as observed from the Swiss operational radar network; 5 years of radar data are processed with a thunderstorm detection and tracking algorithm and ...

Synoptic conditions and atmospheric moisture pathways associated with virga and precipitation over coastal Adélie Land in Antarctica [PDF]

open access: yesThe Cryosphere, 2020
Precipitation falling over the coastal regions of Antarctica often experiences low-level sublimation within the dry katabatic layer. The amount of water that reaches the ground surface is thereby considerably reduced. This paper investigates the synoptic

From model to radar variables: a new forward polarimetric radar operator for COSMO [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
In this work, a new forward polarimetric radar operator for the COSMO numerical weather prediction (NWP) model is proposed. This operator is able to simulate measurements of radar reflectivity at horizontal polarization, differential reflectivity as ...

Microphysics and dynamics of snowfall associated with a warm conveyor belt over Korea [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
On 28 February 2018, 57 mm of precipitation associated with a warm conveyor belt (WCB) fell within 21 h over South Korea. To investigate how the large-scale circulation influenced the microphysics of this intense precipitation event, we ...

Hydrometeor classification through statistical clustering of polarimetric radar measurements: a semi-supervised approach [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
Polarimetric radar-based hydrometeor classification is the procedure of identifying different types of hydrometeors by exploiting polarimetric radar observations.

On the fine vertical structure of the low troposphere over the coastal margins of East Antarctica [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
In this study, 8 years of high-resolution radiosonde data at nine Antarctic stations are analysed to provide the first large-scale characterization of the fine vertical structure of the low troposphere up to 3 km altitude over the coastal ...

Unraveling hydrometeor mixtures in polarimetric radar measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Radar-based hydrometeor classification typically comes down to determining the dominant type of hydrometeor populating a given radar sampling volume. In this paper we address the subsequent problem of inferring the secondary hydrometeor types present ...
