In recent years, the field of videography (the process of obtaining
video imagery) has taken on greater significance in remote sensing
applications. Today studies are being conducted to determine the potential
uses and capabilites of airborne video imagery. In the past, satellite or aerial
photography analysis and interpretation has been...
A nested, nondivergent barotropic numerical weather prediction model for forecasting tropical cyclone motion out to 48 h is initialized at time t = 0 by assimilating data from the preceding 24 h. The assimilation scheme finds the generalized inverse of the model and data for −24 ≤ t ≤ 0....
