ISS nocturnal images as a scientific tool against Light Pollution.https://hdl.handle.net/20.500.14352/45905The potential of the pictures of the Earth taken at night from the International Space Station (ISS) with a Nikon D3s digital camera to fight against light pollution is shown. We show that RAW pictures should be used to obtain fluxes. We have developed a method to perform absolute photometric calibration measuring fluxes of the stars recorded in the pictures and also calibrated sources at earth.engconference paperopen access52-3352Light pollutionRemote sensingPhotometryContaminación lumínicaAstrofísicaAstronomía (Física)
