Utilization of the Suomi National Polar-Orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band for Arctic Ship Tracking and Fisheries Management

摘要: Maritime ships operating on-board illumination at night appear as point sources of light to highly sensitive low-light imagers environmental satellites. Unlike city lights or from offshore gas platforms, whose locations remain stationary one the next, typically are ephemeral. Fishing boat most prevalent near coastal cities and along thermal gradients in open ocean. commercial also operate that can be detected space. Such observations have been made a limited way via U.S. Department Defense satellites since late 1960s. However, Suomi National Polar-orbiting Partnership (S-NPP) satellite, which carries new Day/Night Band (DNB) radiometer, offers vastly improved ability for users observe shipping remote areas such Arctic. Owing S-NPP’s polar orbit DNB’s wide swath (~3040 km), same location Polar Regions observed several successive passes overlapping swaths—offering track ship motion. Here, we demonstrate monitor Imagery DNB is compared with heritage sensor, Operational Linescan System (OLS) on board Meteorological Support Program (DMSP) satellites, evaluated context tracking individual under both moonlit moonless conditions. In statistical sense, show how East China Sea correlated seasonal fishing activity, while revealing compelling structures related regional fishery agreements established between various nations.
