22 new or updated open datasets on AWS: New polar satellite data, blockchain data, and more

The AWS Open Data Sponsorship Program makes high-value, cloud-optimized datasets publicly available on Amazon Web Services (AWS). AWS works with data providers to democratize access to data by making it available to the public for analysis on AWS; develop new cloud-native techniques, formats, and tools that lower the cost of working with data; and encourage the development of communities that benefit from access to shared datasets. Through this program, customers are making over 100PB of high-value, cloud-optimized data available for public use.

The full list of publicly available datasets are on the Registry of Open Data on AWS and are now also discoverable on AWS Data Exchange. This quarter, AWS released 22 new or updated datasets including Amazonia-1 imagery, Bitcoin and Ethereum data, and elevation data over the Arctic and Antarctica. Check out some highlights:

ArcticDEM and the Reference Elevation Model of Antarctica (REMA)

Launched this quarter, ArcticDEM and REMA are the result of an initiative between the National Geospatial-Intelligence Agency (NGA) and the National Science Foundation (NSF) to create a high-resolution, high quality, 3D digital representation of polar regions using high-resolution satellite imagery acquired by Maxar. Led by researchers at the University of Minnesota’s Polar Geospatial Center (PGC), REMA and ArcticDEM provide essential high-resolution terrain maps that help to inform climate policy and national security decision making. Both datasets include large area topographic mosaics and smaller time-dependent elevation data scenes that researchers can use to map the physical environment and observe change through time.

AWS Public Blockchain Data

Bitcoin and Ethereum blockchain datasets are now available in open, cloud-optimized Parquet format via Amazon Simple Storage Service (Amazon S3), managed by AWS. These two datasets simplify cross-chain analytics for researchers and others by providing blockchain data in a consistent format and schema. Additionally, these datasets provide and document a fully open source pipeline for customers wishing to reproduce these datasets or manage their own blockchain data. Read more about these datasets on the AWS Database Blog.

Co-Produced Climate Data to Support California’s Resilience Investments

The Co-Produced Climate Data to Support California’s Resilience Investments dataset includes next-generation climate projections to support energy sector resilience and adaptation planning. In addition, it supports a suite of climate-related research datasets produced for and by California’s Fifth Climate Change Assessment. Regionally downscaled Global Circulation Models (GCM) that contribute to the Coupled Model Intercomparison Project Phase 6 (CMIP6) project form the foundation of the advanced metrics and analytics datasets generated to make climate data actionable. This generation of regionalized data takes a major step forward in spatial resolution (from 6km to 2km) and temporal resolution (daily to hourly). This provides climate data at temporal and spatial scales relevant to infrastructure and community requirements for adaptation planning. In addition to temperature and precipitation, additional climate variables of relevance to stakeholders, such as wind speed and direction, surface solar radiation, relative humidity, and a suite of hydrological variables are regionally downscaled and included in the dataset.

Here is a full list of the datasets released or significantly updated this quarter joining over 350 datasets already available:
