The artificial night sky brightness mapped from DMSP satellite Operational Linescan System measurements
We present a method to map the artificial sky brightness across large territories in astronomical photometric bands with a resolution of approximately 1 km. This is useful to quantify the situation of night sky pollution, to recognize potential astronomical sites and to allow future monitoring of trends. The artificial sky brightness present in the chosen direction at a given position on the Ea...
متن کاملNight sky brightness at sites from DMSP-OLS satellite measurements
We apply the sky brightness modelling technique introduced and developed by Roy Garstang to high-resolution DMSP-OLS satellite measurements of upward artificial light flux and to GTOPO30 digital elevation data in order to predict the brightness distribution of the night sky at a given site in the primary astronomical photometric bands for a range of atmospheric aerosol contents. This method, ba...
متن کاملMaps of Artificial Sky Brightness and Upward Emission in Italy from Dmsp Satellite Measurements
We obtained the map of the zenith brightness of the night sky in Italy, constructing a simple model. The artificial sky brightness in each site is given by the integration of the contribution produced by each unitary area of surface obtained by applying a propagation function to the upward emission in the area. This operation is a convolution of the upward emission with the propagation function...
متن کاملMapping the Artificial Sky Brightness in Europe from Dmsp Satellite Measurements: the Situation of the Night Sky in Italy in the Last Quarter of Century
We present a project to map the artificial sky brightness in Europe in the main astronomical photometrical bands with a resolution better than 3 km. The aim is to understand the state of night sky pollution in Europe, to quantify the present situation and to allow future monitoring of trends. The artificial sky brightness in each site at a given position on the sky is obtained by the integratio...
متن کاملThe Artificial Sky Brightness in Europe Derived from Dmsp Satellite Data
We present the map of the artificial sky brightness in Eu-rope in V band with a resolution of approximately 1 km. The aim is to understand the state of night sky pollution in Europe, to quantify the present situation and to allow future monitoring of trends. The artificial sky brightness in each site at a given position on the sky is obtained by integration of the contributions produced by ever...
