Comparison of temperature-dependent calibration methods of an instrument to measure OH and HO₂ radicals using laser-induced fluorescence spectroscopy [PDF]

Atmospheric Measurement Techniques, 2023
Laser-induced fluorescence (LIF) spectroscopy has been widely applied to fieldwork measurements of OH radicals and HO2, following conversion to OH, over a wide variety of conditions, on different platforms and in simulation chambers.

Errors in stereoscopic retrievals of cloud top height for single-layer clouds [PDF]

Atmospheric Measurement Techniques
Multi-angle stereoscopic methods are a promising means for retrieving high-resolution cloud volumes and their temporal evolution. Stereoscopic retrievals assume that light emerges from localized points on a surface.

Benchmarking and improving algorithms for attributing satellite-observed contrails to flights [PDF]

Atmospheric Measurement Techniques
Condensation trail (contrail) cirrus clouds cause a substantial fraction of aviation's climate impact. One proposed method for the mitigation of this impact involves modifying flight paths to avoid particular regions of the atmosphere that are conducive ...

Riming-dependent snowfall rate and ice water content retrievals for W-band cloud radar [PDF]

Atmospheric Measurement Techniques
Accurate measurements of snowfall in mid-latitudes and high latitudes are particularly important because snow provides a vital freshwater source and impacts glacier mass balances as well as surface albedo.

Radiative closure assessment of retrieved cloud and aerosol properties for the EarthCARE mission: the ACMB-DF product [PDF]

Atmospheric Measurement Techniques
Measurements made by three instruments aboard the EarthCARE satellite, plus data from auxiliary sources, will be used synergistically to retrieve estimates of cloud and aerosol properties. The ACMB-DF processor consists of a continuous radiative closure

Atmospheric stability from numerical weather prediction models and microwave radiometer observations for onshore and offshore wind energy applications [PDF]

Atmospheric Measurement Techniques
Atmospheric stability controls the evolution of wind turbine wakes and thus the yield and performance of wind parks. For estimations of wind park power output and for improving analyses of wind park wakes, crucial parameters were found to be profiles of ...
