xirrus darkness monitoring for Parks and Natural Preserves
For natural preserves and country parks, natural nightly darkness gains relevance.
The effect on biodiversity is undisputed, and observing the immaculate starry sky is very attractive.
- Dark spots and corridors are essential for night-active species.
- Extended dark areas are rare—a very special experience for park visitors that stay over night.
- The sight of a splendid dark starry sky is gorgeous.
The potential certification as internationally recognized dark sky reserve by UNESCO,
or as a star park by DarkSky International, points out the value of the nightly landscape,
that is only to experience if the dark area is vast.
We offer the following services in this sector:
- Night-time cartography
identifies the dark parts of the park, in order to preserve them,
and overly bright areas, in order to curtail their impact on the park.
Such information is helpful in regard to a certification.
- Site Analyses and night-time photography
including quantitive metering of light:
This is ideal for a before/after documentation when public lighting is refurbished,
for example near service facilities, car parkings, or illuminated landmarks.
Such a documentation proves the efforts to protect the darkness, to recognize its value, and
ro verify the success of a lighting management plan.
- Proof of night-time darkness: Using instrumentation such as Sky Quality Meter (SQM) and Sky Brightness Photometer (TESS), we are able to prove that your efforts satisfy the certification conditions.
- All-Sky-Cameras continuously record the darkness—night by night. Incident lights can be quickly recognized and reminded.
Nearby light gleams remain under control.
Trends in light pollution are detected in a short time scale by an automated correction of weather and moonlight.
- Workshops, seminars and conference contributions foster contacts, involve local population, and present the actions in a clear and comprehensible way to the public, authorities, and politics.
