  The manifestation of the dark Universe begun with unexpected large scale
astronomical observations. Here we are investigating the origin of small scale
anomalies, like that of the annually observed temperature anomalies in the
stratosphere. Unexpectedly, we observe a planetary relationship of the daily
stratospheric temperature distribution. Its spectral shape does not match
concurrent solar activity, or solar EUV emission, whose impact on the
atmosphere is unequivocal. This behavior points at an additional energy source
of exosolar origin. A viable concept behind such observations is based on
possible gravitational focusing by the solar system towards the Earth of low
speed invisible matter. We denote generic constituents from the dark Universe
as invisible matter, in order to distinguish them from ordinary dark matter
candidates like axions or WIMPs, which cannot have any noticeable impact on the
stratosphere. The observed peaking planetary relations exclude on their own any
conventional explanation. Only a somehow strongly interacting invisible
streaming matter with the little screened upper stratosphere (noverhead about 1
gr/cm 2) can be behind the occasionally observed temperature increases. We also
estimate an associated energy deposition O(W/m 2), which is variable over the
11 years solar cycle. For the widely assumed picture of a quasi not interacting
dark Universe, this new exosolar energy is enormous. Since the atmosphere is
uninterruptedly monitored since decades, it can serve also parasitically as a
novel low threshold detector for the dark Universe, with built-in
spatiotemporal resolution and the solar system acting temporally as signal
amplifier. In future, analyzing more observations, for example, from the
anomalous ionosphere, or, the transient sudden stratospheric warmings, the
nature of the assumed invisible streams could be deciphered.
