With that location data, the program calculates altitude and azimuth for various objects and also helps the user keep track of other important variables like moon illumination and angle above the ...

A method is presented for calculating the apparent elevation angle to be expected for an object situated in the troposphere at specified values of geometrical elevation angle and height.

The simulation accuracy of the particle-tracking model (PTM) primarily depends on wind and current, among various parameters. This study explored the effect of wind on particle tracking using drift ...
