What is PO.DAAC?

The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is an element of the

Earth Observing System Data and Information System (EOSDIS).

The EOSDIS provides science data to a wide community of users for NASA's Science Mission Directorate.

What does podaacpy offer?

The library provides a Python toolkit for interacting with all PO.DAAC Web Services v3.2.2 APIs, namely

• PO.DAAC Web Services: services include

• Dataset Metadata - retrieves the metadata of a dataset

• Granule Metadata - retrieves the metadata of a granule

• Search Dataset - searches PO.DAAC's dataset catalog, over Level 2, Level 3, and Level 4 datasets

• Search Granule - does granule searching on PO.DAAC level 2 swath datasets (individual orbits of a satellite), and level 3 & 4 gridded datasets (time averaged to span the globe)

• Image Granule - renders granules in the PO.DAAC's catalog to images such as jpeg and/or png

• Extract Granule - subsets a granule in PO.DAAC catalog and produces either netcdf3 or hdf4 files

• Metadata Compliance Checker: an online tool and web

  service designed to check and validate the contents of netCDF and HDF granules for the

  Climate and Forecast (CF) and Attribute Convention for Dataset Discovery (ACDD) metadata conventions.
• Level 2 Subsetting: allows users to subset and download popular PO.DAAC level 2 (swath) datasets.
• PO.DAAC Drive: an HTTP based data access service. PO.DAAC Drive replicates much of the functionality of FTP while addressing many of its issues.

Additionally, Podaacpy provides the following ocean-related data services

• NASA OceanColor Web:
• File Search - locate publically available files within the NASA Ocean Data Processing System (ODPS)
• Bulk data downloads via HTTP - mimic FTP bulk data downloads using the HTTP-based data distribution server.
