Meteorological, Climatological  & Atmospheric Science Professionals from 2026 Federal Directory

Notes: 

1. The Federal Directory of Scientists & Professionals was removed from on line listings in March 2026.  We have captured photos and information on many scientists and researchers who were listed there.   Several are also seen at recent CMOS congresses, presenting, mentoring or chairing sessions.

2. Information on 44 scientists was captured, but only 33 mug photos were downloaded before the firectory was permanently removed.  Photos of 11 more scientists were found from other recent sources and are likely the same as on the deleted Directory. Both groups are posted in alpha order by surname; Please scroll down.
