ECV Inventory Survey Approach

• ECV Inventory Database gathers user input data from an enhanced survey web site: http://ecv-inventory.com/ecv2/

This is a second generation site. Redesign was necessary for integration with the EOHandbook database.

Contains two questionnaires, one for current/existing and one for future climate data records

45 total questions based on 5 topics (General, Usage, Stewardship, Properties, Access)

Many questions use menu selections (12 menus). Some example menus are: Agency, Project, ECV, Satellite, Data Format.

Site has limited search and analytical capabilities. Intended use is strictly to gather data

All data records can be exported to an Excel spreadsheet for analysis purposes or for integration to other applications

Envision this as a living database with the record information updated as agencies desire

Need to decide if a formal annual call to update is appropriate, similar to the MIM 2WGClimate Meeting, Darmstadt, March 4 – 7, 2014

ECV Inventory / Access to Data

• ECV Inventory Database is integrated with the EO Handbook Database (EOHD) for user viewing, searching, and analyzing of climate data records (CDRs)

All CDRs are imported to the EOHD automatically via the Excel interface mentioned earlier

The EO Handbook Database (EOHD) site, formerly referred to as the CEOS Missions, Instruments, and Measurements (MIM) Database contains official agency reported information

EOHD site links the CDRs to the extensive official mission, instrument, and measurement information contained in the EOHD

The EOHD site provides mission timeline analysis for various measurements to promote gap analyses. A similar timeline analysis capability will be available for the CDRs.

- Need to decide if timelines should be displayed for measurements or for ECVs, etc.

Site has good search and analytical capabilities. Intended use is to educate and for users to gather usable information for decision-making

User Specified ECV Inventory Data Query Capability

• Planned Query Capability Search by

Responsible organization, ECV type, TCDR, Physical Quantity (or type of measurement), Satellite, and Instrument

Display records by Calendar timelines for multiple records grouped by ECV type, TCDR, and

Physical Quantity. View additional information beside the timeline? Could include responsible organization, satellite, and instrument

Advanced query of records by Sorting timelines by responsible organization, satellite, and instrument Providing statistics summary counts of number of records per agency, per ECV

type, per TCDR type, etc

Future Plans

• Define Query Capabilities and Expand the EO Handbook to include the ECV Inventory data

• Decide on future survey needs; once a year or ongoing through the ecv-inventory.com site. Data would periodically be imported to the EO Handbook for updates

• Future surveys could be tied to the MIM annual call that goes out in May of each year

• How will this data be used? Will agencies use it to coordinate where to invest resources to obtain a global, continuous climate record?
