Retrieving Environmental Data in R

Eric introduces how to retrieve environmental data from open sources, specifically using NOAA's Air Dub. He guides viewers through accessing the site, exploring available variables like chlorophyll a, and selecting data based on time and location. Eric demonstrates how to download the data in NC file format and use it in R for further analysis.
