Hi Nega,

Look also here for a detailled "recipe" (assuming the earth's vertical circumference at 40,009km):

Hi again,

I remember I had this one in my computer. It is aimed at calculating Great Circle Distances ("A Great Circle Distance is the shortest distance between two points on a sphere. All lines of Longitude are Great Circles.") and it should be of interest to you. Please look at:

and dowload the file here:

It can be used with LibreOffice or OpenOffice Calc too.

what studies are available where students are the main informants for determining impacts of climate change on tourism?

Hi Haretsebe,

This is not the place to start a new question. This thread is about "Distance of a location from the equator".

I would suggest you start a new question on your topic. A the top of this page, on the right side of it you have a button "Ask your own question". You may wish to use it.

Regards,

Tito

Dears,

In association with my previous question about the distanceof a location from the equator, i would like to add another question:

It is clear that equator and areas in the vicinity of equator are warm compared to poles. When we move from the equator to the poles the temperature decreases, but is there a standard poleward decrease in temperature, that means is there temperature gradient when we move from the equator to the poles?

Hi Nega,

The rapid answer would be "off course yes". But clearly things are much more complex at any local level.

I am unsure of what you are looking for when asking your question.

May I suggest that you have a look at some "basics" here:

http://earthobservatory.nasa.gov/Features/EnergyBalance/printall.php

And also to read this book:

Marshall, J., and Plumb, R.A. (2008). Atmosphere, Ocean, and Climate Dynamics: an Introductory Text. Academic Press.

And particularly chapter 8: The general circulation of the atmosphere, which is available here:

http://paoc.mit.edu/labweb/notes/chap8.pdf

Hope this helps,

Tito

You can calculate the distance using the R package "geosphere" (https://cran.r-project.org/web/packages/geosphere/geosphere.pdf).

Make sure your coordinates are in decimal notation and then use one of the functions in this package (e.g. distGeo).

A demo script is attached and also available here: https://github.com/barnzilla/r-scripts
