For a quick introduction to ERDDAP, watch the first half of thisvideo. (5 minutes)
In it, a scientist downloads ocean currents forecast data from ERDDAP to model a toxic spill in the ocean using NOAA's GNOME software (in 5 minutes!). Thanks to Rich Signell. (One tiny error in the video: when searching for datasets, don't use AND between search terms. It is implicit.)
ERDDAP shares a lot with Pydap, my own data server. I should check if I can use GNOME with Pydap like in this video example; it would be interesting, specially now with the Chevron oil spill in Brazil.
