Halo articles in English by FHON members

Here is a list of halo related articles in English language which are published in scientific publications by FHON members. 

The first Finnish made article was by Hakumäki and Pekkola about elliptical halos in Weather in 1989. Most articles are published in Applied Optics by Optical Society of America (OSA) or in Weather by Royal Meteorological Society. 

Articles are in chronological order. The most recent one is on top.
