Mass concentration estimates of long-range-transported Canadian biomass burning aerosols from a multi-wavelength Raman polarization lidar and a ceilometer in Finland [PDF]

Atmospheric Measurement Techniques, 2021
A quantitative comparison study for Raman lidar and ceilometer observations, and for model simulations of mass concentration estimates of smoke particles is presented. Layers of biomass burning aerosol particles were observed in the lower troposphere,

The Influence of Visibility on the Opportunity to Perform Flight Operations with Various Categories of the Instrument Landing System

Sensors, 2023
Meteorological conditions significantly affect air traffic safety and can also affect a pre-planned flight plan. Difficult meteorological conditions are particularly hazardous during take-off and landing procedures. Still, they can also cause disruptions

Merging regional and global aerosol optical depth records from major available satellite products [PDF]

Atmospheric Chemistry and Physics, 2020
Satellite instruments provide a vantage point for studying aerosol loading consistently over different regions of the world. However, the typical lifetime of a single satellite platform is on the order of 5–15 years; thus, for climate studies, the use of

Relation between substorm characteristics and rapid temporal variations of the ground magnetic field [PDF]

Annales Geophysicae, 2006
Auroral substorms are one of the major causes of large geomagnetically induced currents (GIC) in technological systems. This study deals with different phases of the auroral substorm concerning their severity from the GIC viewpoint.
