  We are investigating the possible origin of small-scale anomalies, like the
annual stratospheric temperature anomalies. Unexpectedly within known physics,
their observed planetary "dependency", does not match concurrent solar
activity, whose impact on the atmosphere is unequivocal; this points at an
additional energy source of exo-solar origin. A viable concept behind such
observations is based on possible gravitational focusing by the Sun and its
planets towards the Earth of low-speed invisible streaming matter; its influx
towards the Earth gets temporally enhanced. Only a somehow "strongly"
interacting invisible streaming matter with the small upper atmospheric
screening can be behind the observed temperature excursions. Ordinary dark
matter (DM) candidates like axions or WIMPs, cannot have any noticeable impact.
The associated energy deposition is $\mathcal{O}(\sim 1000\,
\mathrm{GeV}/{{\mathrm{cm}}^2}/\mathrm{sec})$. The atmosphere has been
uninterruptedly monitored for decades. Therefore, the upper atmosphere can
serve as a novel (low-threshold) detector for the dark Universe, with built-in
spatiotemporal resolution while the solar system gravity acts temporally as a
signal amplifier. Interestingly, the anomalous ionosphere shows a relationship
with the inner earth activity like earthquakes. Similarly investigating the
transient sudden stratospheric warmings within the same reasoning, the nature
of the assumed "invisible streams" could be deciphered.
