Journal Citation Reports is a database that, among other features, will provide you with a list of top journals in your chosen subject area...atmospheric science, ecology, environmental science, fisheries, forestry, soil science, wildlife. (For some areas, you will have to compile two or more subject lists.)
After you've searched for your topic in a database and found citations to articles, while still in the database, you'll usually see this button, near the citation.
Just click on and often you'll be taken directly to the full text (usually a PDF) of the article.
Below is a list of databases or electronic indexes that will allow you to search by topic keyword, author, etc. to find citations, abstracts, and full-articles from thousands of journals, magazines, and other sources.
Ellis Library also has a collection of recently published print journals. The newest print journals are arranged in alphabetical order on the shelves in the Reference stacks in Information Commons 2 (IC2), just north of the DVDs and East of the Government Documents. Older volumes/years are stored in the regular shelves of Ellis Library. To find older journals, you can look up the journal by name in MERLIN to get its call number.
