The ASDC led a "Cloud Access Mini-Workshop" that demonstrated virtual dataset capabilities for satellite data analysis. Participants learned hands-on techniques for accessing TEMPO Level-3 data using the Openscapes 2i2c JupyterHub in AWS Cloud—approaches that directly support NASA's Open Science principles by making data more accessible and analyses more efficient and easy to collaborate on.

**Tackling Real Challenges Together**

The workshop addressed a common challenge: satellite data stored in traditional HDF and netCDF formats can be slow to access and download from the cloud. A collaborative team spanning NASA DAACs (Distributed Active Archive Centers), Openscapes, OPeNDAP (Open-source Project for a Network Data Access Protocol), and open source contributors is working to solve this through innovative approaches like DMR++ reference files and VirtualiZarr tools that create "virtual datasets" without requiring massive downloads.

The hands-on session featured engaging experimentation with TEMPO satellite data, where participants explored treating individual data granules as virtual datasets. The collaborative discussion also identified concrete opportunities to improve tools like earthaccess to make virtual datacube workflows even more user-friendly.
