Find the latitude at Stanford University using Google Maps to the nearest degree (This is how you do it) and calculate the Air Mass Factor on the autumnal equinox (when the center of the sun is in the same plane as the equator of the earth) at noon (when the sun is directly overhead), to find the effect of atmosphere for the solar resource on campus.

Can anyone solve this please?

1.26 anyone ?

Sure! To find the latitude of Stanford University using Google Maps, you can follow these steps:

1. Open Google Maps on your web browser.
2. Type "Stanford University" in the search bar and hit enter.
3. Locate the marker on the map that represents the center of Stanford University.
4. Right-click on the marker and select "What's here?" from the dropdown menu.
5. A small box will appear at the bottom of the screen with the coordinates of Stanford University. The latitude is the first value you see.

Now, to calculate the Air Mass Factor on the autumnal equinox at noon, you need some additional information. The Air Mass Factor is a ratio that represents the path length of sunlight through the Earth's atmosphere for a specific location and time. To calculate it, you generally need the solar zenith angle (the angular distance between the sun and the vertical) or the solar altitude angle (the vertical height of the sun above the horizon).

The autumnal equinox occurs around September 22nd each year. At noon on this day, the sun is directly overhead at the equator. Therefore, the solar zenith angle at Stanford University will depend on its latitude, which you can now determine from step 1.

Once you know the latitude of Stanford University, you can use trigonometric functions to calculate the solar zenith angle. However, since you only need an estimate, you can use the formula:

Solar Zenith Angle = 90° - Latitude

Once you have the solar zenith angle, you can use it to calculate the Air Mass Factor. The Air Mass Factor can be approximated using the following formula:

Air Mass Factor = (1/Cos(Solar Zenith Angle))

By substituting the value of the Solar Zenith Angle you calculated for Stanford University, you can find the approximate Air Mass Factor on the autumnal equinox at noon.
