ERDDAP is an environmental data server providing a simple, consistent way to:
It transparently acts as a middleman between you and environmental
data on disparate data servers.
- perform data analysis and visualization, e.g. to make maps and plots of
- download subsets of gridded and tabular scientific datasets in the file
formats of your choice
- use programming languages such as R and Python to access
and analyze data from within your own programs
Please use the following CoastWatch servers. Note that generally each server
hosts different data sets with some overlap. East Coast Node is in the
process of adding data sets to the CoastWatch-Central ERDDAP server.
Caribbean/Gulf of Mexico Node
West Coast Node
Pacific (Hawai'i) Node
Online tutorials for using ERDDAP:
Some ERDDAP features:
- Make customized maps and time series plots and export them as .png
or .pdf images.
- Include a customized map or plot in your own web pages using just a URL
to the ERDDAP server. The URL permits automatic real-time satellite updates
of your map or plot on your website.
- Export data in the format of your choice, e.g.
.html table, ESRI .asc and .csv, Google Earth .kml, .mat, .nc, .txt, .csv,
.json, and .xhtml
- Both satellite (grid) and in-situ (tabular) data are included on
ERDDAP servers, facilitating analyses for spatial and temporal environmental
ERDDAP is created and maintained by NOAA Fisheries Service, Southwest Fisheries
