This article aims to evaluate impact of image saturation on radiometric intercalibration Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) stable nighttime light (NTL) images. We simulated two sets NTL images, one with and the other without saturation, by using DMSP/OLS radiance calibrated images saturation. For each dataset, we intercalibrated seven years a quadratic regression model. found that saturation-derived difference is more obvious in areas where...
We proposed a method for intercalibration between DMSP/OLS radiance calibrated images and NPP/VIIRS based on stable pixels, while the challenge is that these two datasets do not have overlapped periods. In this study, outliers, which are changed were iteratively removed considering radiometric spatial differences kinds of images, then pixels obtained. Using intercalibrated regression model. Taking mainland China as an experimental region, we obtained DMSP-like VIIRS from 2013 to 2019. The...
Abstract Estimating ice resistance and ship motion in ice-covered region is important for the planning of operations transport routes. This paper proposes a numerical simulation method predictions loads motions level ice. The dynamic interaction between considered on basis nonlinear finite element method. Numerical simulations are carried out by LS-DYNA software. material model which can simulate crushing bending failure modes used. To consider net thrust during ship-ice interaction,...
Two types of nighttime light products were derived from the Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS). One called stable (NTL) is saturated in urban centers, and other radiance calibrated (RCNTL) does not have saturation. This study compared these two images three perspectives. For radiometric attributes, fitted well by both power function logarithmic whole China with lowest R2 value 0.867 highest 0.937, fitting performed better. In addition, complex...
