Cloud Computing for Science Data Processing in Support of Emergency Response

The new package can be quickly deployed on a cloud computing platform only for as long as processing of the time series data is required. Stennis Space Center, Mississippi In a crisis, up-to-date information is one of the most important commodities for decision-makers. Remote sensing data have been instrumental in regional scale damage detection and recovery progress monitoring after significant disasters. However, using remotely sensed data to support an emergency response requires not only the availability of hardware, software, and manpower to process and analyze the data, but also the time to stage the datasets that are required for analyses. Additionally, the volume of remote sensing data that needs to be processed to detect temporal changes accurately in a terrestrial or oceanic ecosystem can easily exceed several terabytes, even for a small region. This is because emergency response requires the use of well-calibrated remotely sensed data products, like those that are generated by the MODIS (Moderate Resolution Imaging Spectroradiometer) Adaptive Processing System (MODAPS). These data sets are stored and distributed by the Level 1 and Atmosphere Archive and Distribution System (LAADS), both located at Goddard Space Flight Center (GSFC), and are necessary to create the custom data products that are needed and used for emergency management situations. Generally, the MODIS datasets are downloaded from GSFC, stored at the user’s facility, and then processed locally. This approach is standardly used by researchers worldwide.

Simulating Images of a Rising or Setting Sun

NASA’s Jet Propulsion Laboratory, Pasadena, California This software simulates Sun images observed on the ground and from space with an easy-to-use analytical approach and with high accuracy. It is a simple, analytical approach with the accuracy of a rigorous, multilayer model. The existing analytical approach cannot predict when the image of the Sun is blocked by the surface of the Earth, but the current approach can.

Partition Level Application Test for Orion (PLATO)

Lyndon B. Johnson Space Center, Houston, Texas For Orion Exploration Flight Test One (EFT-1), the unit-under-test for flight software verification has been chosen as the entire integrated flight software load. At the time of this reporting, the unit test tool, while powerful, operates on very small units, usually classes. This leaves a sizable gap between unit testing and verification. Orion flight software is divided into ARINC 653 partitions, and partition level testing is in this large gap.

Simulating Data Flow via Multiple Secure Connections

Goddard Space Flight Center, Greenbelt, Maryland A software simulator was developed to simulate data flow from the Interface Data Processing Segment (IDPS) to the Science Data Segment (SDS) for the NPOESS Preparatory Project (NPP) via multiple Secure FTP (sftp) connections. The simulator is a multi-threaded Java program that handles the continuous sftp transfer of large amounts of data with some error-handling capabilities built in.

Gridded Atmosphere Products from GPS Radio Occultation Measurements with Bayesian Interpolation Technique

NASA’s Jet Propulsion Laboratory, Pasadena, California GPS radio occultation measurements are vital for climate monitoring and atmospheric temperature change detection. However, the data are irregularly distributed in space and time, which makes it inconvenient for many applications.

Goddard Mission Services Evolution Center Compliance Test Suite

Goddard Space Flight Center, Greenbelt, Maryland To reduce the cost of building specialized interfaces, missions can adopt Goddard Mission Services Evolution Center (GMSEC) technologies and applications. Assurances need to be made that application implementation should follow the GMSEC messaging standards. The GMSEC Interface Specification Document (ISD) sets forth definitions for all GMSEC message types.
