Description
General purpose R client for ERDDAP servers
ERDDAP info
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
ed_search, list datasets via ed_datasets,
get information on a single dataset via info, then get
data you want for either tabledap type via tabledap, or
for griddap type via griddap.tabledap/griddap
tabledap and griddap have different interfaces to query for data, so
tabledap and griddap 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 via griddap 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 griddap
for more details.
