Comments on Air Mass


I think there might be a mistake in the AM formula for the shadow stick.
sqrt(1+(h/s)^2) is what I derived

Estimo que tu error esta en haber considerado el angulo de altitud solar no el de cenit. La expresion utilizada en el texto esta correcta.

Respected Sir/Madam,
Our team is going to publish a Chapter in book namely, "Borate Phosphors Processing to Application" in CRC Press, Taylor & Francis Group, LLC.
In this book of chapter 8, I am going to use a Air mass ratio above figure from this site"
So please kindly convey your permission or NOC for the same.

with regards

I stumbled upon this page when trying to figure out sunset on planets other than Earth. Unfortunately, your formula is assuming no curvature of the planet. Put in an angle of 90 and nothing comes through--but that's not what we see when we watch a sunset.
