Examples

data <- data.frame(Latitude = 32, Longitude = -117,
                   UTC = as.POSIXct('2000-01-01 00:00:00', tz='UTC'))
## Not run: 
# not run because download could take time
# download jplMURSST41 dataset
edi <- erddapToEdinfo('jplMURSST41')
ncFile <- downloadEnv(data, edi, 'sstData.nc')

# browse suggested sst datasets, then download
edi <- browseEdinfo(var='sst')
ncFile <- downloadEnv(data, edi, 'sstData.nc')

## End(Not run)
