Cylindrical solar altitude and azimuth graphs. Available in 5 minute, 15 minute and 60 minute durations. Then, we used those coordinates to calculate look angles (azimuth and elevation) from the observer's position to an orbiting satellite. Launch azimuth calculator. Airmassor secz:another measure of altitude is Airmass, which measures path-length. Inspired by the calculator request /3004/: "There is an excellent, in my understanding, calculator that helps to calculate sun azimuth for each point on the globe and its angle to the horizon at a given time. Then determine the arcsine of the result, which will give you the azimuth angle.
