Comment ce site est financé, et ce que cela change ou ne change pas.

Northern Lights Index has not published any tours rows yet. The first check is pending, so nothing on this site is a measured figure.

A comparison page is published once we can count at least 5 tours on it.

We may earn a commission if you book through links on this page, at no extra cost to you. No booking links are live yet.

The full note is this page. Rankings follow the dataset, not the payout.

## Where does Northern Lights Index get these numbers?

Nothing is sourced yet. When the first check runs, every row will carry the operator or marketplace listing it was read from and the date it was read. Clear-sky and dark-hours figures will be computed from public climate normals and from astronomy formulas, and the methodology page will name each source and its reuse terms.

## Do you earn money from the links?

We may earn a commission if you book through links on this page, at no extra cost to you. No booking links are live yet.

## Why is a place missing?

A place is published once we can count at least 5 tours there. Smaller places wait until the list is more useful.
