DOI: 10.1007/s00128-017-2058-x
Abstract: In this study, ambient NH3, NO, NO2, CO and SO2 were measured continuously from February, 2008, to December, 2016. The annual average mixing ratios (mole/mole) of NH3, NO, NO2, CO and SO2 were 17.8 ± 3.4 ppb; 21.2 ± 2.3 ppb,… read more here.

DOI: 10.1111/1365-2656.12850
Abstract: The vast majority of species interactions are seasonally structured and depend on species' relative phenologies. However, differences in the phenologies of species naturally vary across years and are altered by ongoing climate change around the… read more here.

DOI: 10.5194/angeo-39-255-2021
Abstract: Abstract. Ground-based observations show a phase shift in semi-annual variation of excited hydroxyl ( OH∗ ) emissions at mid-latitudes (43 ∘ N) compared to those at low latitudes. This differs from the annual cycle at… read more here.
