DRL 2008 Highlights

Simulcast Version 4.1 Released – 8/5/2008

The DRL is pleased to announce a new release of Simulcast (Version 4.1). This release includes Simulcast Services for both Linux and Windows users, as well as Version 4.1 of the Simulcast Viewer for Windows, published as a self-installing package. 

Simulcast is a multi-mission tool that allows users to select and view quicklook instrument data, in real time and with a single Viewer. The Simulcast Services processes and visualizes instrument data in real time, and accepts as input CCSDS packet streams (e.g., RT-STPS).

Enhancements in v4.1:
Simulcast Version 4.1 addresses stability issues when multiple viewers are simultaneously connected to a server at resolutions greater than 1 km.  It is encouraged that all users update to v4.1

As an element of the IPOPP framework (a leveraged NISGS technology), Simulcast provides the real-time quicklook visualization capability.

MODLST_SPA Version 4.14 Released – 7/11/2008

The DRL is pleased to announce the release of the MODLST_SPA (Version 4.14).  The MODLST algorithm was provided to the DRL by the MODIS Land Rapid Response Team. 

This Land Surface Temperature (LST) algorithm uses brightness temperatures in MODIS bands 31 and 32 to produce day and night LST products at 1-km spatial resolutions in swath format. It uses MODIS Level 1B 1-km and geolocation HDF files and outputs LST in HDF.

The MODLST_SPA has been packaged with the DRL's algorithm wrapper, and fulfills the objectives of a Modular Components Approach (MCA) for Earth Science data processing implementation. 

The algorithm wrapper provides a common command and execution interface to encapsulate multi-discipline, multi-mission SPAs.  The wrapper also provides a structured, standardized technique for packaging new or updated algorithms with minimal effort.  All of the processing algorithms and processing packages released by the DRL conform to this common Application Programming Interface (API).

L2GEN_SPA Version 5.8.3 Released – 7/9/2008

The DRL is pleased to announce the release of the L2GEN_SPA (Version 5.8.3).  The science algorithms within L2GEN (formerly MSL12) are provided by the Ocean Biology Processing Group (OBPG). 

This implementation of L2GEN is a source of science-sanctioned MODIS Level 2 Ocean Color and Sea Surface Temperature products from inputs of MODIS Level 1B 1km (MOD021KM/MYD021KM) products, MODIS Geolocation (MOD03/MYD03) products, and other optional ancillary files.

The L2GEN_SPA has been packaged with the DRL's algorithm wrapper, and fulfills the objectives of a Modular Components Approach (MCA) for Earth Science data processing implementation. 

The algorithm wrapper provides a common command and execution interface to encapsulate multi-discipline, multi-mission SPAs.  The wrapper also provides a structured, standardized technique for packaging new or updated algorithms with minimal effort.  All of the processing algorithms and processing packages released by the DRL conform to this common Application Programming Interface (API).

MOD09_SPA Version 5.3.18 Released – 6/28/2008

The DRL is pleased to announce the release of the MOD09_SPA (Version 5.3.18).  This Land Surface Reflectance Science Processing Algorithm (SPA) uses the MODIS 1km, half km, and quarter km L1B Calibrated Geolocated Radiances HDF and MODIS Geolocation HDF input products, and utcpole, leapsec, and meteorology ancillary files, to create the MODIS Level 2 Land Surface Reflectance Product.

The MOD09_SPA allows processing of arbitrary sized granules, and simplifies the ancillary data requirements. The MOD09_SPA will work with either the grib1 or grib2 ancillary files. Beginning in September 2008, the NCEP meteorology data will be available in grib2 format only.

The MOD09_SPA has been packaged by both the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the DRL, and fulfills the objectives of a Modular Components Approach (MCA) for Earth Science data processing implementation.

The algorithm wrapper provides a common command and execution interface to encapsulate multi-discipline, multi-mission SPAs.  The wrapper also provides a structured, standardized technique for packaging new or updated algorithms with minimal effort.  All of the processing algorithms and processing packages released by the DRL conform to this common Application Programming Interface (API).

MODISL1DB_SPA Version 1.5 Released – 4/14/2008

The DRL is pleased to announce the release of the MODISL1DB_SPA (Version 1.5). The MODIS Level 1 Direct Broadcast Science Processing Algorithm (SPA) processes Level 0 MODIS data into Level 1A (MOD01/MYD01) and Geolocation (MOD03/MYD03) products. It also processes Level 1A and Geolocation products into MODIS Level 1B one km (MOD021KM/MYD021KM), half km (MOD02HKM/MYD02QKM), and quarter km (MOD02QKM/MYD02QKM) granules.

The MODISL1DB_SPA v1.5 package has been tested successfully on the following versions of Linux: CentOS, Fedora, Kubuntu, and SUSE. This release contains no processing code changes, however, the Ocean Biology Processing Group (OBPG) MODISL1DB 1.5 distribution has been updated to include statically linked binaries. This may allow users to run MODISL1DB on a wider variety of unsupported Linux systems.

This latest MODISL1DB SPA has been packaged with the DRL's algorithm wrapper, and fulfills the objectives of a Modular Components Approach (MCA) for Earth Science data processing implementation.

The algorithm wrapper provides a common command and execution interface to encapsulate multi-discipline, multi-mission SPAs.  The wrapper also provides a structured, standardized technique for packaging new or updated algorithms with minimal effort.  All of the processing algorithms and processing packages released by the DRL will conform to this common Application Programming Interface (API).

IPOPP Alpha Test Program – 2/22/2008

The DRL has launched an Alpha Test Program to deliver evolving NPP In-Situ Ground System (NISGS) technologies to Alpha test sites for evaluation on the road to NPP.  The International Polar Orbiter Processing Package (IPOPP) leverages the NISGS technologies to maximize the utility of Earth science data for real-time decision-making.  The DRL has delivered technolgies to the following Alpha test sites:

• United States Department of Agriculture (USDA) Forest Service Remote Sensing and Applications Center (RSAC)
• Oregon State University (OSU)
• University of South Florida (USF)
• National Institute for Space Research (INPE)
• National Commission for Biodiversity of Mexico (CONABIO)
• Center for Rapid Environmental Assessment and Terrain Evaluation (CREATE)
• Landgate Satellite Remote Sensing Services

It is important to note that the DRL continues to work closely with the science discipline teams from Land, Ocean and Atmosphere (respectively:  the MODIS Land Rapid Response Team, the Ocean Biology Processing Group, and the Cooperative Institute for Meteorological Satellite Studies) to bring you standalone versions of Science Processing Algorithms (SPAs). 

Click here to view the IPOPP User's Guide, Version 1.5a, included with the initial IPOPP Alpha Test Program release.
