1. Community Based Initiatives GES DISC UWG 2011 Meeting

2. 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)

3. ESIP Discovery ClusterESIP 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 2010Discovery Cluster  Push harder in this area?  Extensions to ESIP Convention?  Reference implementations?

4. ESIP Information Quality ClusterESIP 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

5. 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

6. 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?

7. 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

8. GEWEX / CEOPGEWEX / 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

9. GEWEX Aerosol Assessment Panel (GAAP)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.

10. GAAP ReportsGAAP 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.

11. Community-Based GiovanniCommunity-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)

12. Other Community InitiativesOther 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.

13. Discussion  Not enough or too much involvement in technology-oriented communities?  Not enough involvement in science communities?  Typically need an invitation...
