For over 20 years, ESIP meetings have brought together the most innovative thinkers and leaders around Earth science data, thus forming a community dedicated to making Earth science data more discoverable, accessible and useful to researchers, practitioners, policymakers, and the public. The theme of this year’s meeting is "Data for All People: From Generation to Use and Understanding."

Unlocking ARCO: Analysis-Ready Cloud-Optimized Data transformation in practice

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Feedback form is now closed.
Experience is the best teacher. Data providers need a space to share their experiences generating ARCO (analysis-ready cloud-optimized) datasets and use the ESIP Winter session to collect best practices and examples.

The Cloud Computing Cluster is excited to organize this session which will produce “real outputs” in the form of best practices, guidance and use case driven workflow with examples which will be formalized in github repositories and shared through social media such as LinkedIn, twitter and slack.

The Cloud Computing Cluster is composed of members from data and service providers such as USGS, NASA, NOAA, cloud providers such as AWS and Microsoft, and academic institutions such as UCAR/NCAR and the University of Washington. The January meeting provides an opportunity for these organizations to share and coalesce on best practices for analysis-ready cloud-optimized (ARCO) data.

Lightning Talks

Four (4) 5-minute lightning talks
  1. Dieu My thanh Nguyen on Zarr chunking strategies research 
  2. Anderson Banihirwe on producing Zarr data store for the complex climate model data (Community Earth System Model Large Ensemble (CESM LENS) Data Sets on AWS - Datasets - DASH Search - PRODUCTION)
  3. Lucas Sterzinger on Fake it until you make it — Reading GOES NetCDF4 data on AWS S3 as Zarr for rapid data access
  4. Landung (Don) Setiawan on building data portals for OOI and other NASA-funded projects requiring large-scale data conversion and utilization of both COG and Zarr.
pangeo-forge with Charles Stern

Pangeo Forge is an open source tool for data Extraction, Transformation, and Loading (ETL). The goal of Pangeo Forge is to make it easy to extract data from traditional data repositories and deposit in cloud object storage in analysis-ready, cloud-optimized (ARCO) format.

Kerchunk with Lucas
Cloud-friendly access to archival data. Kerchunk is a library that provides a unified way to represent a variety of chunked, compressed data formats (e.g. NetCDF, HDF5, GRIB), allowing efficient access to the data from traditional file systems or cloud object storage.

  • Keywords Cloud Computing, Data Stewardship
  • Collaboration Area Tags Cloud Computing, Community Data
  • Target Audience The target audience is anyone who is interested in generating cloud-optimized data archives and/or has experience doing so. The cloud computing cluster is composed of data providers and technologists who have affiliations from federal agencies to academic institutions and share the mission of making Earth observation archives more accessible to a greater number of people. We believe creating more and better cloud-optimized data archives will make that possible.
