Argo ERDDAP Use Cases

In this repo, we'll show some use cases of the Argo data ERDDAP API hosted by Ifremer:

You can run and edit example notebooks by running this repo on Binder (thanks Pangeo):

Argo Data Fetcher

We develop high level helper methods to load Argo data that is available for the Ifremer erddap server. The argopy library is still in active development.

Usage to fetch Argo data from the erddap:

    from argopy import DataFetcher as ArgoDataFetcher

    argo_loader = ArgoDataFetcher()
    argo_loader = ArgoDataFetcher(backend='erddap')
    argo_loader = ArgoDataFetcher(cachedir='tmp')

    argo_loader.profile(6902746, 34).to_xarray()
    argo_loader.profile(6902746, np.arange(12,45)).to_xarray()
    argo_loader.profile(6902746, [1,12]).to_xarray()

    argo_loader.float(6902746).to_xarray()
    argo_loader.float([6902746, 6902747, 6902757, 6902766]).to_xarray()
    argo_loader.float([6902746, 6902747, 6902757, 6902766], CYC=1).to_xarray()

    argo_loader.region([-85,-45,10.,20.,0,1000.]).to_xarray()
    argo_loader.region([-85,-45,10.,20.,0,1000.,'2012-01','2014-12']).to_xarray()
