Dark skies can affect our experience of nature, landscapes and greenspaces and can benefit our health and wellbeing and local wildlife.


The Dark Sky and Light Pollution Dataset for Wales has been created to identify the strategic and local resource in remote, rural, peri-urban and urban areas for use as an evidence base to inform policy intent, practice and provision for benefits to benefits to wellbeing.


The dataset is based upon satellite imagery taken at 1:30 A.M in December 2019 by the United States National Oceanic and Atmospheric Administration (NOAA) Suomi National Polar-orbiting satellite with the Visible Infrared Imaging Radiometer Suite (VIIRS) capturing visible and infrared imagery used in this dataset and later processed in 2021.


A set of maps have been created to display the dark skies data against the following geographical boundaries:


- Local Authority areas

- Future Wales boundaries

- Designated landscapes (AONBs and National Parks)

- NRW Operational Areas

- National Landscape Character Areas

- LANDMAP Visual & Sensory aspect areas

Gall awyr dywyll effeithio ar ein profiad o fyd natur, tirweddau a mannau gwyrdd a gall fod o fudd i’n hiechyd a’n lles a’n bywyd gwyllt lleol. Mae Set Ddata Awyr Dywyll a Llygredd Golau Cymru wedi’i chreu i nodi’r adnoddau strategol a lleol mewn ardaloedd anghysbell, gwledig, ardaloedd trefol a’r ardaloedd o amgylch trefi i’w defnyddio fel sylfaen dystiolaeth i gyfarwyddo bwriad, gweithrediad a darpariaeth polisi ar gyfer buddion llesiant.


Mae'r set ddata yn seiliedig ar ddelweddau lloeren a gymerwyd am 1:30 AM ym mis Rhagfyr 2019 gan loeren Partneriaeth Suomi National Polar-orbiting a’r United States National Oceanic and Atmospheric Administration (NOAA) gyda'r VIIRS (Visible Infrared Imaging Radiometer Suite) sy’n cipio delweddau gweladwy ac isgoch a ddefnyddir yn y set ddata hon ac a broseswyd yn ddiweddarach yn 2021.


Mae set o fapiau wedi'u creu i ddangos data'r awyr dywyll yn erbyn y ffiniau daearyddol canlynol:

Ffiniau Cymru'r Dyfodol

Tirweddau dynodedig (Ardaloedd o Harddwch Naturiol Eithriadol a Pharciau Cenedlaethol)
