Calibration and assessment of electrochemical low-cost sensors in remote alpine harsh environments
(Journal article; Peer reviewed, 2021)This work presents results from an original open-source low-cost sensor (LCS) system developed to measure tropospheric O3 in a remote high altitude alpine site. Our study was conducted at the Col Margherita Observatory ... -
CALOTRITON: a convective boundary layer height estimation algorithm from ultra-high-frequency (UHF) wind profiler data
(Journal article; Peer reviewed, 2024)Long time series of observations of atmospheric dynamics and composition are collected at the French Pyrenean Platform for Observation of the Atmosphere (P2OA). Planetary boundary layer depth is a key variable of the climate ... -
Correcting the impact of the isotope composition on the mixing ratio dependency of water vapour isotope measurements with cavity ring-down spectrometers
(Journal article; Peer reviewed, 2020)Recent advances in laser spectroscopy enable high-frequency in situ measurements of the isotope composition of water vapour. At low water vapour mixing ratios, however, the measured stable water isotope composition can be ... -
The COTUR project: remote sensing of offshore turbulence for wind energy application
(Journal article; Peer reviewed, 2021)The paper presents the measurement strategy and data set collected during the COTUR (COherence of TURbulence with lidars) campaign. This field experiment took place from February 2019 to April 2020 on the southwestern coast ... -
Differential absorption lidar for water vapor isotopologues in the 1.98 μm spectral region: Sensitivity analysis with respect to regional atmospheric variability
(Journal article; Peer reviewed, 2021)Laser active remote sensing of tropospheric water vapor is a promising technology to complement passive observational means in order to enhance our understanding of processes governing the global hydrological cycle. In ... -
Exploring the potential of the RPA system SUMO for multipurpose boundary-layer missions during the BLLAST campaign
(Peer reviewed; Journal article, 2016-06-24)In June and July 2011 the RPAS (Remotely Piloted Aircraft System) SUMO (Small Unmanned Meteorological Observer) performed a total number of 299 scientific flights during the BLLAST (Boundary Layer Late Afternoon and Sunset ... -
A flexible device to produce a gas stream with a precisely controlled water vapour mixing ratio and isotope composition based on microdrop dispensing technology
(Journal article; Peer reviewed, 2023)Here we describe a versatile device to produce a gas stream with a precisely controlled water vapour mixing ratio and stable water isotope composition based on microdrop dispensing technology. To produce a moist ... -
A modular field system for near-surface, vertical profiling of the atmospheric composition in harsh environments using cavity ring-down spectroscopy
(Journal article; Peer reviewed, 2023)Cavity ring-down spectroscopy (CRDS) has allowed for increasingly widespread, in situ observations of trace gases, including the stable isotopic composition of water vapor. However, gathering observations in harsh environments ... -
Observing atmospheric convection with dual-scanning lidars
(Journal article; Peer reviewed, 2023)While convection is a key process in the development of the atmospheric boundary layer, conventional meteorological measurement approaches fall short in capturing the evolution of the complex dynamics of convection. To ... -
Proof of concept for turbulence measurements with the RPAS SUMO during the BLLAST campaign
(Peer reviewed; Journal article, 2016-10-06)The micro-RPAS (remotely piloted aircraft system) SUMO (Small Unmanned Meteorological Observer) equipped with a five-hole-probe (5HP) system for turbulent flow measurements was operated in 49 flight missions during the ... -
Rotary-wing drone-induced flow - Comparison of simulations with lidar measurements
(Journal article; Peer reviewed, 2024)Ultrasonic anemometers mounted on rotary-wing drones have the potential to provide a cost-efficient alternative to the classical meteorological mast-mounted counterpart for atmospheric boundary layer research. However, the ... -
An unmanned aerial vehicle sampling platform for atmospheric water vapor isotopes in polar environments
(Journal article; Peer reviewed, 2021)Above polar ice sheets, atmospheric water vapor exchange occurs across the planetary boundary layer (PBL) and is an important mechanism in a number of processes that affect the surface mass balance of the ice sheets. Yet, ... -
A versatile water vapor generation module for vapor isotope calibration and liquid isotope measurements
(Journal article; Peer reviewed, 2024)A versatile vapor generation module has been developed for both field-based water vapor isotope calibrations and laboratory-based liquid water isotope measurements. The vapor generation module can generate a stream of ...
