Fetching Argo meta-data¶
Since the Argo measurements dataset is quite complex, it comes with a collection of index files, or lookup tables with meta data. These index help you determine what you can expect before retrieving the full set of measurements. argopy
has a specific fetcher for index:
[2]:
from argopy import IndexFetcher as ArgoIndexFetcher
index_loader = ArgoIndexFetcher()
[3]:
idx = index_loader.region([-75, -45, 20, 30, '2011-01-01', '2011-05'])
idx
