Abstract During spring 2020, the COVID-19 pandemic caused massive reductions in emissions from industry and ground airborne transportation. To explore resulting atmospheric composition changes, we conducted BLUESKY campaign with two research aircraft measured trace gases, aerosols, cloud properties boundary layer to lower stratosphere. From 16 May 9 June performed 20 flights early lockdown phas...

This study aimed to observe the influence of weather parameters (irradiation, ambient temperature, PV module wind speed, and direction). Performance evaluation rooftop systems is carried out according IEC 61724-1:2017. The measured are solar irradiance using a pyranometer, surface temperature sensor, direction Smart Weather Sensor Lufft type WS500-UMB. analysis was performed under three differe...
