SWOT Data Access Workshop by NASA’s PO.DAAC

In person at AGU Chapman: Remote Sensing of the Water Cycle


Cassie Nickles & Catalina Taglialatela


Welcome to the 2024 SWOT Data Access Workshop hosted by PO.DAAC!

The workshop will take place in person at the AGU Chapman: Remote Sensing of the Water Cycle Conference on Tuesday, February 13, 2024 from 9am-12:30pm in Honolulu, HI.


Workshop Goals

  • Provide an inclusive place to learn about and experience working with SWOT’s Hydrology Data;
  • Provide strategies and best practices for finding and accessing NASA Earthdata in the Cloud. Specifically, participants will learn how to access data from AWS S3 buckets and have a better understanding of the Python ecosystem used to analyze the data depending on size and data formats;
  • Better understand the needs of Earthdata data scientists by providing a post survey and engaging in discussions with workshop participants;
  • Practice using popular open source tools and utilities.

Workshop Description

The Surface Water and Ocean Topography (SWOT) satellite, a joint NASA-CNES venture, provides unprecedented measurements of surface water extents and elevations for hydrologic science and applications. The observations are offered through a range of data products including river and lake vector data in shapefiles, and raster, pixel cloud, and pixel vector data in netCDF. The shapefile products will also contain estimates of river discharge and lake storage change. In this pre-meeting workshop, participants will be introduced to SWOT and the various ways to access and utilize its data products, including via cloud computing, local download, and data transformation tools. Participants will be able to utilize a provided cloud computing environment accessed via personal laptops, or their own laptop’s compute power to explore SWOT data using data recipes by PO.DAAC, NASA’s Physical Oceanography Data Active Archive Center. No prior cloud computing experience is necessary. We welcome all to come and see how SWOT data could augment existing workflows or initiate new, innovative science and applications! The data tutorials at the workshop will use Python, but no prior experience is needed.
