Why Share Data?

As open data policies become commonplace, it is worth examining the history and value of open data, and discuss why we share it in the cloud. The idea of sharing data dates back at least to the 1950s, when the International Council of Scientific Unions established World Data Centers to facilitate sharing of data among scientists. In recent years, governments have created open data policies that require government agencies to share data with the public.

Estimating Hurricane Wind Speeds with Machine Learning

Better estimates of hurricane wind speeds can lead to better decisions around evacuations and general hurricane response planning, saving both lives and property. Hurricane windspeed estimates are currently made using the manual Dvorak technique. The National Hurricane Center releases them every three to six hours. Artificial intelligence (AI) experts with the IMPACT team at NASA’s Marshall Space Flight Center and Development Seed created the Deep Learning-Based Hurricane Intensity Estimator to automate this process.

The ERA5 Reanalysis Dataset Provides a Sharper View on Past Weather

Reanalysis is the term for using modern-day technology to analyze weather data from the past. By doing so, meteorologists and climatologists can produce a more accurate analysis of previous weather conditions, which is important for climate change research. The European Centre of Medium Range Forecasts (ECMWF) is producing its latest reanalysis dataset, called ERA5. Recently, Chris Kalima and his team at Intertrust, in conjunction with the AWS Public Datasets Program, have been working to bring the ERA5 data to AWS.

Hubble Space Imagery on AWS: 28 Years of Data Now Available in the Cloud

Since going live in 1990, the Hubble Space Telescope has delivered groundbreaking images to broaden our understanding of the universe. Each image captured by the telescope is archived and made publicly available, free of cost, by NASA through the Space Telescope Science Institute (STScI). The Hubble images archive is used by a global community of astronomers, researchers, and engineers and has led to the discovery of distant galaxies and nebulae. “The legacy is a treasure trove of data that can be mined in the future,” Arfon Smith, head of data science at STScI, said.

Achieving Sustainable Development in Africa with Open Data

Achieving sustainable development and addressing local and national needs requires access and analysis of large datasets and the use of complex tools and algorithms. This creates barriers for many users, particularly for communities in developing countries where resources for data storage and data analysis are limited. The African Regional Data Cube (ARDC), a new data management technology developed on AWS, hopes to address this challenge by building capacity in those communities to access large datasets in support of their local and national needs framed around the Sustainable Development Goals (SDGs) and the broader development priorities.

Urban Climates: Calculating the Sky View Factor for the Netherlands

Imagine you are on a city street surrounded by skyscrapers. When you look up to the stars, you will only see the part of the sky that is not blocked by buildings. This type of vision is called sky view factor (SVF). The SVF denotes the ratio between the radiation received at a point on Earth and the available radiation for a hemisphere over that point. Dr. Andrea Pagani, a data scientist at the DataLab of the Royal Netherlands Meteorological Institute, has been looking at how to efficiently compute the SVF for the Netherlands. Read on to learn more about Dr. Pagani’s work to help us understand what’s between us and the sky – and why that matters.

The Opioid Council: Public Health Leaders Address Addiction

To kick off the AWS Opioid Crisis Council’s inaugural meeting, AWS public health leader, Michael Jackson, convened a panel of healthcare experts at the AWS Public Sector Summit in Washington, DC. Government health officials, research scientists, pharmacy executives, and industry pioneers examined proposed solutions with open data, and shared ideas for attacking this complex issue. All stakeholders rallied around a common customer: our community.
