erddap: ERDDAP Information

Description

NOAA's ERDDAP service holds many datasets of interest. It's built on top of OPenDAP http://www.opendap.org/. You can search for datasets via erddap_search, list datasets via erddap_datasets, get information on a single dataset via erddap_info, then get data you want for either tabledap type via erddap_table, or for griddap type via erddap_grid.

Details

tabledap and griddap have different interfaces to query for data, so erddap_table and erddap_grid are separated out as separate functions even though some of the internals are the same. In particular, with tabledap you can query on/subset all variables, whereas with gridddap, you can only query on/subset the dimension varibles (e.g., latitude, longitude, altitude). NOTE: With griddap data vai erddap_grid you can get a lot of data quickly. Try small searches of a dataset to start to get a sense for the data, then you can increase the amount of data you get. See erddap_grid for more details. The following are the ERDDAP functions:

• erddap_search
• erddap_datasets
• erddap_info
• erddap_table
• erddap_grid
