Making NASA Data Sets Available with GIS-based Web-Applications for Energy: POWER/SSE v8 Paul Stackhouse, NASA LaRC Jason Barnett and Tyler Bristow, Booz-Allen-Hamilton at NASA LaRC William Chandler*, James Hoell, and David Westberg, SSAI at NASA LaRC And the Atmospheric Science Data Center * In memoriam to William S. Chandler, principle web developer for early versions SSE/POWER

POWER Overview Objectives: Improve the Nation’s public/private capability for integrating environmental data from NASA research to support increased renewable energy development, building energy efficiency and agricultural modeling. Goals: Through partnerships, derive/validate/provide parameters relevant to industry needs, link to decision support, and transition capabilities when possible.

Current POWER/SSE Renewable Energy Data Products Old POWER (SSE v6) Achievements: 22 Years (1ox1o, climatology) Over 200 parameters, many on the fly, customized for renewable energy Daily time series via Sustainable Buildings and Agroclimatology Data quality information Direct connection to 2 energy DSS tools SSE usage: >27 Million data requests fulfilled for v 6.0 Approx: 275K hits, 200K downloads, 4-6 GB and 15K users per month Data requests from 215 nations, islands and territories in 2017 alone Issues: Data sets becoming outdated Data served only in ASCII format Data backend production not scalable; requires a complete rewrite to reprocess Original graphics no longer supportable due to software and security issues http://eosweb.larc.nasa.gov/sse 10/10/17 ASES Solar 2017

New POWER/SSE (v8, GIS) Expands Accessibility with Web Services POWER Applied Science project aims to make NASA data more accessible Website is a Responsive Platform for Desktop, Tablet, and Smartphone New POWER Website serves as a platform for discovery of multiple data access points Updated data sets with future updates more easily implemented, documented and validated POWER web site now in beta: power.larc.nasa.gov/new 10/10/17 ASES Solar 2017

POWER (v8, GIS): From Data Source to User MERRA 2 Native meteorological model data is ingested and processed on a recurring cycle and stored. A A GEOS 5.12.4 1 Native solar model data is ingested on a recurring cycle and averages greater than daily are processed and stored. B 1 3 Data is served to users via Custom Python API utilizing OPeNDAP and Esri ArcGIS Server (Image Services). 2 2 SRB 3.0 3 Users can access the data in commercial and custom applications via Desktop, Tablet and smartphone technologies. B CERES FLASHFlux 2H-3C Native Gridded Model Data Data Not Distributed* Data Distributed Data Stored Recurring Python Scripts Server with Enterprise GeoDatabase Web Server Users Access On Responsive Platform * Data may become available in future depending on resources and user requirements.
