Biodiversity SBA – Status Biodiversity community had a meeting in early March and discussed biodiversity priority observations. Results of meeting TBD.
In discussion with Michele Walters (GEO BON Exec. Officer) about a Biodiversity SBA report
- Need to follow the 9-step process for consistency- Report outline and observation list to combination into Cross-SBA
Timeline TBD
When/if they produce a report, this will require a revision to Final Cross-SBA report

US-09-01a Gap AnalysisReport Recommendation: Conduct an assessment of the current andplanned availability of the priority Earth observations.
Assess Current and Planned Availability of Observat ions- Up to 15 years for planned missions- Approx. top 30-35 observations from report- Initial Focus on Satellite observations
Use CEOS Mission, Instruments, and Measurements” databaseas primary source
Parameters to CaptureSatellite name, instrument, and primary agencyType of satellite (GEO or LEO) and geographic coverageMeasurement type (e.g., precipitation rate) and unitsTemporal and spatial resolutionSatellite launch date and planned end of life date
Identify any temporal or geographic measurement gap s
Gap Analysis: Process
1. Use the entries in the CEOS Measurements, Instruments, and Missions (MIM) database (http://database.eohandbook.com/) as a basis for determining available satellite measurements.
2. For each listed instrument/satellite in CEOS database, conduct internet searches to locate specific measurement information and datasets, and record measurement information (when available):– Satellite name, instrument, and primary agency
– Type of satellite (GEO or LEO) and geographic coverage
– Measurement type (e.g., precipitation rate) and units
– Temporal and spatial resolution
– Satellite launch date and planned end of life date
9
Gap Analysis: Results to Date
• Analysts have gathered information on measurements for 5 of the top 10 highest-ranked parameters (precipitation, soil moisture, surface air temperature, vegetation cover, NDVI)
• Example – excerpt of results for precipitation :
Current Planned
Currently there are: 40 measurements from 14 instruments on 26 satellitesfor precipitation
In planning stages, there are17 instrumentsfor precipitation

Gap Analysis: Findings to Date
• Ease of public access to on-line measurement datasets varies by sponsoring agency
• Existence of multi-observation blended products is a complicating factor (not listed in CEOS database)
• In some cases, there is limited information on specific measurements for planned satellite missions– Limits the ability to assess transition from current to planned
satellite products

US-09-01a Parameter CharacteristicsReport Recommendation: Gather information and engage users on specific characteristics of the priority Earth observations, especially Precipitation.
Users and ApplicationsExamine users and applications across SBAs as systematic way to capture breadth of needs (e.g., famine early warning, agriculture production, hydropower, flood prediction, landslides, tropical cyclones, numerical weather prediction systems, groundwater recharge)
Parameter CharacteristicsAssess the needed parameters in the breadth of applications and users to identify common loci of common parameter needs- e.g., some may need weekly averages at 1km resolution, some mayneed 1º x 1º every hour
This activity is currently being done for precipitation , could be repeated for other observations, such as soil moisture or land cover.
Parameter CharacteristicsProcess
Activity in Process:1.Assemble a preliminary list of users, purposes, and
required characteristics of precipitation info from:- Documents cited in individual SBA reports (over 50 documents
already analyzed) to capture details- Documents provided by other precipitation working groups
(Step 1 is ~70% complete)
Next Steps:2.Gather feedback via presentations/discussions with 12-15
relevant organizations (including GEO CoPs)3.Compile final results.

Parameter Characteristics: Excerpt of User Needs Analysis
Parameter Characteristics
Findings to Date – Part A
• Certain user types are well-represented in literature:– Climate researchers
– Emergency/disaster response managers
– Resource managers (water, forests)
– Forecasters (weather, hydrologists)
• These tend to be users of primary precipitation data.
• There is especially strong user interest in forecasts.
19
Parameter Characteristics
Findings to Date – Part B
• Certain user types are under-represented in literature:– Financial Sector Managers (e.g., Risk Assessors)
– Policy Makers (e.g., Advisory Organizations, Elected Officials, and Policy Analysts)
– Regulators (e.g., Permitting Agencies, Energy Commissions)
– Engineers (e.g., Civil Engineers, Chemical Engineers)
– Various others: Coastal Managers, Aviation Industry/Pilots Electric Grid Operators, Utility Companies, Journalists,
– Private Citizens & Civic Leaders
• These tend to be users of secondary precipitation products.
20
Next Steps
• Complete the Gap Analysis (satellite measurement availability) for top 30-35 highest-ranked observations– Several high-priority indirect/modeled observations (e.g.,
urbanization, stream/river flow, cultivation, deforestation, soil composition) are not categories in the CEOS database and will beexcluded or treated separately
• Use initial results from the Parameter Characteristics to reach out to GEO COPs and other user organizations to identify additional information on specific user needs for precipitation
Estimated date of completion for Activities: Fall 2011
21
Uses of Gap Analysis and Precipitation Characteristics Results
• GEO Members can:– Use results to support planning for future satellite missions– Identify key opportunities to serve their users’ needs
• GEO Committees and Tasks can:– Examine access to high priority observations through GEOSS– Identify key gaps in current and planned availability of priority
observations
• COPs can:– Inform members about available satellite measurement for high
priority observations
• Users can: – Advocate to fill gaps and weaknesses of high priority observations– Recognize users with similar needs and collaborate

Panels 5 & 6 are interactive. We have a hand-out with instructions. Also, there are color stickers (panel 5) & and a card (panel 6).
For Panel 5, people can “vote” for five observations. The panel has a large table of SBAs (along top) and Observations (along left side). Each person will get five colored stickers to affix to the panel. They can put their stickers in boxes corresponding to an observation and a SBA associated with their priority. We’ll tally the results at the end.
Voting multiple times over multiple days is not permitted.

For Panel 6, people can identify an important observation that doesn’t appear on Panel 5. It’s their chance to tell us of an additional observation. There will be cards for people to fill-out and then affix to Panel 6. The cards ask them to identify:
- Observation- Name, Organization, Email- How observation is used & why it’s important
