Measurements in the lower free troposphere
Research gap analysis derived from 3 earth_science papers in our local library.
The gap
However, measurements in the lower free troposphere – a representative atmospheric layer characterizing regional background conditions in aerosol transport and atmospheric evolution – remain sparse, especially in regions influenced by both anthropogenic emissions and long-range transported air masses.
