Presentation Outline• Activities planned for 2012

– Review of EOSDIS evolution activities in which LANCE will participate• UWG comments are solicited on how these activities will

impact the NRT user community and areas for improvement– Specific enhancements LANCE

Integration with earthdata.nasa.gov

• Harmonize access to NRT and Science products with a consolidated website– Ensure sufficient guidance to inform

NRT or Science product selection by users

• Reduce barriers to accessing NRT products throughout EOSDIS and NASA – For example ocean products (GHRSST)

without extending the scope of LANCE by leveraging existing systems

– Linkages to Direct Readout Lab

• Support central/single location for tools, documentation, user support and user profile management

• Leverage and expose evolving EOSDIS-Wide capabilities – Collaboration (Wiki, Forum)– Web services (Simple Subset Wizard,

Other DAAC tools)05/04/23 3NASA LANCE UWG Meeting - Washington D.C.

Deploy EOSDIS-Wide URS• LANCE implemented a prototype

User Registration System in early 2010 which has been highly successful for communicating data/service issues to users and understanding usage

• An EOSDIS-wide system has been developed and will supplant the prototype for LANCE elements by late spring 2012– Highly stable and scalable system– User accounts will be migrated from

the prototype system; the transition will be communicated to users

– One Username One Password - The EOSDIS-wide URS will be rolled out to DAACs and other resources

– Management of accounts will be from earthdata.nasa.gov

Prototype Global Image Browse System Enhancements

• Global Image Browse System (GIBS) is comprised of the Tiled Web Map Server (TWMS) and an Openlayers Client (Worldview)

– Currently only NRT datasets are– Investigating science products from DAACs to

extend browse beyond 10-day LANCE rolling store – potentially to entire mission

– Rapid Response subsets will be powered by the TWMS simplifying sustaining engineering and subset creation and management

• Collaborations with brokerage users (Lots of interest)

– ECHO to test browse capabilities embedded in Reverb and powered by GIBS

– EPA for AIRNow

• Worldview enhancements– Add additional data layers from existing EOSDIS

WMS capabilities (SEDAC, PO.DAAC)– Specific user interface modifications were

covered in Ryan’s presentation

• Investigate/implement TWMS enhancements – Reduced product generation latency– Test scaling and certificate based access– Ensure attribution to NASA and lineage

Prototype Datacasting for LANCE

• Datacasting, developed by PO.DAAC, is an extension of RSS (Really Simple Syndication)

– Simplifies notifications for available data– Web services and RSS aggregators can

harvest feeds as they become available (Low Latency updates)

– Users can subscribe to Datacasting feeds and be notified when granules meeting search criteria are available

• LANCE can leverage this technology to populate the ECHO metadata repository

– One location to search for Science and NRT data

– Low latency because of immediate availability of feeds

– The ECHO Reverb search and order tool is being integrated into Earthdata for one stop shopping

• Technology enables multiple other mashups of data, geo tagged news and events

– Intersects RSS, GeoRSS and Datacast– Examples flooding in Thailand, fires in

Russia

FIRMS Integration• FIRMS will be integrated into

LANCE and subsequently earthdata.nasa.gov by late March 2012– Capabilities include (Interactive Web

GIS, Email alerts, Subsets of MODIS images, Active fire data downloads (KML, Shapefiles)

– Approximately 1600 fire alerts are distributed daily in the current system (dependent on fire activity)

• EOSDIS user registration, Worldview visualization, metrics and other capabilities will be incorporated over time.

• Investigations are being considered to extend FIRMS functionality to other instrument parameters (AOD, SO2, etc…)– Question for the UWG - Worthwhile?

Latency Improvements

• Additional EDOS enhancements are being considered to reduce latency for Aqua and Aura LANCE products

• Terri Wood (EDOS) will address this after lunch

05/04/23 8NASA LANCE UWG Meeting - Washington D.C.

LANCE Products• Helen Conover will discuss AMSR-E status and product options for

a number of different operating scenarios later this afternoon

• Implement NRL Assimilation product– Agreement reached with NRL in November to transfer AOD

processing code

• Implement Collection 6 MODIS Land Water Mask

• Implement KNMI OMI L3 products after the Ozone (OMTO3) product begins utilizing dynamic row anomaly handling

• Refine and add to application Use Case Matrix and product usage guidance

• The UWG is encouraged to suggest additional capabilities and products during the afternoon session.

New Product Request - AIRS• AIRS Deep Convection Product• Proposal:

– Add a product that conveys information on instances of deep convection to the suite of products available via WMS from LANCE AIRS. This product would support the severe storms use case from the LANCE Use Case Matrix. The product added to LANCE WMS is a daily global map brightness temperature from AIRS L1B radiances of the 1231 cm-1 channel.

– A deep convective cloud is any structure which causes the brightness temperature over non-frozen land or ocean in the 13 km AIRS footprint to be less than 210 K in the 1231 cm-1 window channel.

• Science Heritage – Yes. This is simply a threshold applied to an

existing AIRS product.

• Resources/Schedule– Approximate schedule: 4 weeks for dev/test, 1

week for implementation in Ops– Additional resources required for dev/test and

implementation: none– Projected availability of the global maps via

WMS: mid-201205/04/23 10NASA LANCE UWG Meeting - Washington D.C.

User Product Request – MODIS ET

• MODIS Evapotranspiration (ET)

• Proposal:– The purpose of the suggested enhancement is to generate georeferenced daily

Evapotranspiration (ET) analyses on a near real-time basis. Based on the MOD16 product developed by the University of Montana, this enhancement would provide information on a critical component of the water cycle in support of numerous applications. In particular, this data would be a significant contribution to the NASA partnership with USAID and the World Bank on the Middle East North Africa Water Information Systems Platforms project (MENA WISP).

• Science Heritage – Yes. MOD16

• Who is requesting the effort?  (User)– Shahid Habib is requesting the effort. Dr. Habib is Chief of the NASA GSFC Office of Applied

Sciences and the Project Manager for the NASA-USAID-World Bank MENA WISP project. End Users in this project include the national hydrological and meteorological agencies of Morocco, Tunisia, Egypt, and Jordan.

• Who is completing the effort?  (Provider)– LANCE MODIS

• Is there a HQ or Science sponsor?– At NASA HQ, this would fall under the purview of the Applied Sciences Program, Water

Management element (PE: Brad Doorn).

• Resources/Schedule– TBD
