Challenges

• How can GES DISC tools be reused for new missions to reduce mission costs, while providing the flexible system needed to facilitate science?

• How can GES DISC expertise be utilized in the formulation of new missions?

• Are the GES DISC work directions consistent with the objectives of the NASA Earth science program and its research communities?

• Integrating information services as a commodity item in the science community.

MEaSUREs Projects at GES DISChttp://disc.sci.gsfc.nasa.gov/measures

ESDRs generated by projects funded by the NASA MEaSUREs progra will be archived at various NASA data centers. The GES DISC MEaSUREs portal will include data from seven projects:•Reprocessing and Goddard Satellite-based Surface Turbulent Fluxes (GSSTF) Data Set for Global Water and Energy Cycle Research•Creating a Long Term Multi-Sensor Ozone Data Record•Consistent Long-Term Aerosol Data Records over Land and Ocean from SeaWIFS•GOZCARDS: Global OZone Chemistry And Related Trace Gas Data Records for the Stratosphere•Earth Surface and Atmosphere Reflectivity Since 1979 from Multiple Satellites (TOMS, SBUV, SBUV-2, OMI, SeaWiFS, NPP, and NPOESS)•A Multi-Sensor Water Vapor Climate Data Record Using Cloud Classification•Developing Consistent Earth System Data Records for the Global Terrestrial Water Cycle

Earth Science Data Recoveryhttp://disc.sci.gsfc.nasa.gov/nimbus

Nimbus II, III, IV IR data have been recovered from reel to reel tapes, have been validated, and are now available on-line. Besides making historical data available, it provides lessons for preparing data for long termdata access.

NEESPIhttp://disc.sci.gsfc.nasa.gov/neespi

Allows analyses of interdisciplinary parameters from multi-satellites observations and numerical models over the Northern Eurasia (ACCESS)

ATDDhttp://disc.sci.gsfc.nasa.gov/atdd

Processes, archives, allows access to, visualize, analyze and correlate distributed atmospheric measurements from A-Train instruments.  Provides easy on-line data access and services for science, applications, and educational use so that users get exactly the co-registered data they want. (ACCESS)

NASA Imagery in Virtual Globeshttp://disc.sci.gsfc.nasa.gov/googleearth/overview/

Some GES DISC data is available on Google Earth to facilitate scientific research. Imagery includes two dimensional (2D) flat data and three dimensional (3D) vertical data.

YOTChttp://disc.sci.gsfc.nasa.gov/YOTC

Year of Tropical Convection (YOTC) provides a unique and comprehensive multi-sensor satellite and model data set that is designed to facilitate the study and model improvement of “tropical convection” and its multi-scale organization.

The Atmospheric Composition Constellation (ACC) and the Workgroup for Information Systems and Services (WGISS) within the Committee on Earth Observation Satellites (CEOS) is developing a portal to support interoperability among the atmospheric composition research and applications communities.

Atmospheric Composition Portalhttp://wdc.dlr.de/acp/

Giovanni is augmented with semantic web technologies and ontologies to support data inter-comparisons; Data provenance is added to help researchers make valid data comparisons and draw quantitative conclusions on specific analysis; Encode dataset variable characteristics to derive inter-comparison rules (ESTO)

AeroStatOnline platform for the statistical intercomparison of aerosols, provide online environment for convenient access to satellite and ground-based aerosol data, quality information and provenance, and calibration/validation data. Provides multi-sensor services: intercomparison, cross-sensor bias adjustment, merging. Creates collaborative environment for aerosol researchers. (ACCESS)

Agriculture Decision Supporthttp://disc.sci.gsfc.nasa.gov/agriculture

Monitoring global agricultural crop conditions and estimating seasonal production are critical for market development of U. S. agricultural products and global food security. Operational users of precipitation (TRMM) and soil moisture (AMSR-E/UAH) data for global crop monitoring are the USDA Foreign Agricultural Service (FAS), the USDA World Agricultural Outlook Board (WAOB), and the U.N. World Food Program (WFP). (REASoN, ACCESS)

GLORY launch: Mar. 2011

Glory is a remote-sensing Earth-orbiting observatory designed to achieve two separate mission objectives. One is to collect data on the chemical, microphysical, and optical properties, and spatial and temporal distributions of aerosols. The other is to continue collection of total solar irradiance data for the long-term climate record.
