MY NASA DATA (MND) is a tool that allows anyone to make use of satellite data that was previously unavailable.Through the use of MND’s Live Access Server (LAS) a multitude of charts, plots and graphs can be generated using a wide variety of constraints. This site provides a large number of lesson plans with a wide variety of topics, all with the students in mind. Not only can you use our lesson plans, you can use the LAS to improve the ones that you are currently implementing in your classroom.

This link provides information and additional metadata related to the NASA Socioeconomic Data and Applications Center (SEDAC) Global Volcano Hazard Frequency and Distribution dataset. A direct download is available at https://sedac.ciesin.columbia.edu/downloads/data/ndh/ndh-volcano-hazard-frequency-distribution/gdvol.zip (note: Earthdata Login required for download: https://urs.earthdata.nasa.gov/)Background on Hazard Explorer Tool:The Hazard Explorer Tool is a web mapping application available in FEMA's Preparedness Toolkit that allows exercise planners to identify hazards that exist in their community, where their population is most vulnerable, and where their critical infrastructure/key resources are at risk.The Hazard Explorer Tool was developed under the National Exercise Program, which serves as the principal mechanism for examining the preparedness and readiness of the United States across the entire homeland security and management exercise. Communities design, coordinate, conduct, and evaluate exercises across the US as a part of their preparedness efforts.The Map Journal serves as a tool to help you identify and evaluate potential exercise scenario locations, hazard exposure, and other risk-related factors to support exercise planning. In this tool, you will identify:Which hazards exist near your location;Where your population is most vulnerable; andWhat infrastructure and resources would be most impacted in your selected scenario location.The final output of this tool is a basic PDF map of your selected scenario location, as well as links to data sources that you can share with your GIS staff to conduct more in-depth analysis for use in planning and conducting your exercise.For more information on the Hazard Explorer Tool, please visit: https://preptoolkit.fema.gov/web/hazard-explorer/hazard-explorer-tool

Motivation/Problem Statement: DEREChOS is a natural advancement of the existing, highly-successful Automated Event Service (AES) project. AES is an advanced system that facilitates efficient exploration and analysis of Earth science data. While AES is well-suited for the original purpose of searching for phenomena in regularly gridded data (e.g., reanalyses), targeted extensions would enable a much broader class of Earth science investigations to exploit the performance and flexibility of this service. We present a relevancy scenario, Event-based Hydrometeorological Science Data Analysis, which highlights the need for these features that would maximize the potential of DEREChOS for scientific research.

Proposed solution: We propose to develop DEREChOS, an extension of AES, that: (1) generalizes the underlying representation to support irregularly spaced observations such as point and swath data, (2) incorporates appropriate re-gridding and interpolation utilities to enable analysis across data from different sources, (3) introduces nonlinear dimensionality reduction (NDR) to facilitate identification of scientific relationships among high-dimensional datasets, and (4) integrates Moving Object Database technology to improve treatment of continuity for the events with coarse representation in time. With these features, DEREChOS will become a powerful environment that is appropriate for a very wide variety of Earth science analysis scenarios.

Research strategy: DEREChOS will be created by integrating various separately developed technologies. In most cases this will require some re-implementation to exploit SciDB, the underlying database that has strong support for multidimensional scientific data. Where possible, synthetic data/inputs will be generated to facilitate independent testing of new components. A scientific use case will be used to derive specific interface requirements and to demonstrate integration success.

Significance: Freshwater resources are predicted to be a major focus of contention and conflict in the 21st century. Thus, hydrometeorology and hydrology communities are particularly attracted by the superior research productivity through AES, which has been demonstrated for two real-world use cases. This interest is reflected by the participation in DEREChOS of our esteemed collaborators, who include the Project Scientist of NASA SMAP, the Principal Scientist of NOAA MRMS, and lead algorithm developers of NASA GPM.

Relevance to the Program Element: This proposal responds to the core AIST program topic: 2.1.3 Data-Centric-Technologies. DEREChOS specifically addresses the request for big data analytics, including tools and techniques for data fusion and data mining, applied to the substantial data and metadata that result from Earth science observation and the use of other data-centric technologies.

TRL: Although AES will have achieved an exit TRL of 5 by the start date of this proposed project, DEREChOS will have an entry TRL of 3 due to the new innovations that have not previously been implemented within the underlying SciDB database. We expect that DEREChOS will have an exit TRL of 5 corresponding to an end-to-end test of the full system in a relevant environment.

The NASA Technical Standards Program provides access to NASA developed standards and handbooks. The NASA Standards and Technical Assistance Resource Tool, or START, is a Web tool sponsored by the NASA Technical Standards Program. The idea is to make it simpler for technical people to access great NASA technical information quickly and conveniently.

M2TMNPTRB (or tavgM_3d_trb_Np) is a 3-dimensional monthly mean data collection in Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2). This collection consists of assimilations of turbulence diagnostics on 42 pressure levels, such as total scalar diffusivity, total momentum diffusivity, momentum diffusivity from Louis, and Richardson number from Louis. The information on the pressure levels can be found in the section 4.2 of the MERRA-2 File Specification document. The collection also includes variance of certain parameters.

MERRA-2 is the latest version of global atmospheric reanalysis for the satellite era produced by NASA Global Modeling and Assimilation Office (GMAO) using the Goddard Earth Observing System Model (GEOS) version 5.12.4. The dataset covers the period of 1980-present with the latency of ~3 weeks after the end of a month.
