Community Based InitiativesGES DISC UWG 2011 Meeting
An Acronym Field Guide to Communities
Earth Science Data Systems Working Group (ESDSWG) 4 Working Groups: Metrics, Reuse, Technology
Infusion, Standards and Processes Federation of Earth Science Information Partners
(ESIP) Global Energy and Water Cycle Experiment
(GEWEX) Committee on Earth Observing Satellites (CEOS)
Working Group on Information Systems and Services (WGISS)
Atmospheric Composition Constellation (ACC)
ESIP Discovery Cluster
Began in 2008 at ESDSWG Meeting “Why So Difficult?” rant
Federated solution proposed to community Federated Recursive OpenSearch Toolset (FROST)
Federated Search cluster founded in 2009 Federated Search combined with data- and
service-casting to form Discovery Cluster in 2010 Push harder in this area?
Extensions to ESIP Convention? Reference implementations?
ESIP Information Quality Cluster Objectives
Bring together various disciplines to assess aspects of quality of remote sensing and model data
Share best practices Develop a framework for consistent capture,
harmonization and presentation of data quality Current Activity
Prepare for ESIP Summer Meeting with theme “Data and Information Quality”
Long-term White paper describing needs, standards and
recom-mendations for handling remote sensing data quality
ESDSWG Technology Infusion Working Group
Mandated as part of ACCESS Project wins Standards and Processes Group
E.g., Capability Vision, Decadal Survey Use Cases
Services, Interoperability, and Orchestration Spinoff of Federated Search
Semantic Web Semantic Web tutorial at ESIP Technology infusion into GES DISC
Data Stewardship Kind of lurking so far
WGISS Architectural Development Committee
Ad hoc participant Co-authored white paper on “Challenges
to Seamless Data Discovery and Access to Remote Sensing Data” Also an IGARSS Paper this year What next??? (How to solve???)
Consulting on CEOS WGISS Integrated Catalog (CWIC) Federated search based on OGC standards
Push to solve Challenges to Seamless Data Discovery?
WGISS / Atmospheric Composition Portal
Originally formed out of CEOS Atmospheric Composition Constellation Now under WGISS
Joint project between NASA and DLR (German space agency)
Brings DLR, DataFed and GES DISC data together Level 3 gridded data only
Interesting technology testbed WCS as data exchange Common Style Layer Descriptors for data
comparisons BUT: needs more science direction
GEWEX / CEOP
Coordinated Energy and Water Cycle Observations Project Spearheaded by T. Koike
Developing AIRS subsets for ingest into CEOP Satellite Data Gateway L1 and L2 for Reference sites (250 x 250
km) L2 Monsoonal subsets Reproject/grid and reformat to CEOP
format Mostly best-effort basis
GEWEX Aerosol Assessment Panel (GAAP)
NASA Radiation Science Program, requested by GEWEX Radiation Panel
Evaluate State-of-the-Science of the efficacy of commonly used satellite aerosol products.1.Assess literature on satellite remote sensing of
aerosols and application to the science community.
2.Identify gaps and key stumbling blocks in the use of such data.
3.Based on 1) and 2), conduct key experiments and studies to clarify product efficacy.
4.Make recommendations on programmatic and developers level to improve product quality and applicability.
GAAP Reports
In the first report, provide a broad overview of available and a thorough literature review of past work.
Identify key milestones and areas of concern and provide recommendations for the scientific community and further investigation.
In subsequent reports, provide independent evaluation of baseline and aggregated products.
GES DISC: Gregory Leptoukh, active in multi-sensor aerosol data intercomparison.
Community-Based Giovanni Designed to allow people external to the GES DISC to
support their own datasets and portals e.g., CERES, TES, MODIS...
Conditions for community providers Standard file format and/or protocol
HDF-EOS*, netCDF/CF OPeNDAP (preferred), anonymous FTP
ESIP OpenSearch support (ECHO or own server) Level 3 regular grids only NAMS/IdMAX identity
Prototype Data wizard Portal Constructor (in progress)
Other Community Initiatives Simple Subset Wizard: 10 EOS Data
Centers(!) Giovanni for external data
e.g., ASDC for CERES, TES, MODAPS for MODIS atmospheres products
Data Quality Screening Service: partner with MODIS
Collaborative Energy and Water Cycle Information Services (CEWIS): workshop
Geodata 2011: data lifecycle, integration and citation
CUAHSI*: working on time series capability*Consortium of Universities for the Advancement of Hydrologic Science, Inc.
Discussion
Not enough or too much involvement in technology-oriented communities?
Not enough involvement in science communities? Typically need an invitation...
