AWS adds NEXRAD open data tools

As part of its research agreement with the National Oceanic and Atmospheric Administration, Amazon Web Services began housing a real-time feed and archived data from Next Generation Weather Radar (NEXRAD), providing researchers with high-resolution Doppler radar information they could use for storm predictions or weather related research.
In January, AWS also added two new tools for analyzing and using NEXRAD data through its Amazon Simple Storage Service.
The open-source Java tool WeatherPipe makes it easier to visually analyze NEXRAD data by structuring the information into usable formats and running the job in Amazon Elastic MapReduce to produce NetCDF files, according to AWS. This format allows users to display the data in visualization tools, such as Unidata’s Integrated Data Viewer.
The developers plan to use WeatherPipe to run more advanced and specific analyses, such as storm identification and classification, and eventually create a predictive model for high-impact weather events.
Additionally, AWS created a way to alert users that new objects have been added to Amazon S3.
The Amazon Simple Notification Service creates a notification for every new object added to the Amazon S3 buckets. Users can subscribe to these notifications using Amazon Simple Queue Service and AWS Lambda. This service lets users automatically add new real-time and near-real-time NEXRAD data into a queue or trigger event-based processing if the data meets certain criteria, such as geographic location, AWS said.
