Thermospheric Energy and Heating Due To Upward Propagating and in Situ Generated Tides During Solar Cycle 24

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigate vertical and horizontal energy transport and associated heating in the thermosphere due to both upward propagating and in situ generated migrating and nonmigrating diurnal and semidiurnal tides over the solar cycle 24 (2009–2019).

Noise hazard to the population of areas connected with functioning of roadway frontier crossings

open access: yesArchives of Acoustics, 2014
In spite of Polish observing the Schengen Convention connected with the freedom of internal moving in European Union, the problem of operating the external frontiers is still valid. Such border crossings can be crossed only at the special border crossing

Determination of combustion gas temperatures by infrared radiometry in sooting and nonsooting flames [PDF]

open access: yes
Flame temperatures in nonsooting and sooting environments were successfully measured by radiometry for pre-mixed propane-oxygen laminar flames stabilized on a water-cooled, porous sintered-bronze burner. The measured temperatures in the nonsooting flames

Passive Microwave Radiometry and Active Radar Sounding as Complementary Tools for Geophysical Investigations of Icy Ocean Worlds

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Juno Microwave Radiometer (MWR) observations of Europa and Ganymede offer critical insights into the icy shells of these moons ahead of NASA's Europa Clipper and ESA's JUpiter ICy moons Explorer (JUICE) missions. Both missions are equipped with active radar sounders designed to address key unknowns such as ice shell thickness, thermal state ...
