I work on ERDDAP, a free and open source data server that gives you a simple, consistent way to download subsets of gridded and tabular scientific datasets in common file formats and make graphs and maps. ERDDAP has been installed and used by more than 70 organizations around the world. ERDDAP is on NOAA's list of recommended data servers. See https://coastwatch.pfeg.noaa.gov/erddap/index.html
