A consistently processed annual global nighttime lights time series (2012–2019) was produced using monthly cloud-free radiance averages made from low light imaging day/night band (DNB) data collected by the NASA/NOAA Visible Infrared Imaging Radiometer Suite (VIIRS). The processing steps are modified original methods developed to produce products nightly data. Only two years of VIIRS (VNL) were...

Abstract. Consistent and continuous data on glacier surface velocity are important inputs to time series analyses, numerical ice dynamic modeling mass flux computations. Since 2014, repeat-pass synthetic aperture radar (SAR) have been acquired by the Sentinel-1 satellite constellation as part of Copernicus program EU (European Union) ESA Space Agency). It enables global, near-real-time-like ful...
