1 Linking GDIS Data Sets Using the NIDIS Drought Portal Richard R. Heim Jr. Michael J. Brewer NOAA/NESDIS/ Asheville, North Carolina International Global Drought Information System Workshop: Next Steps Caltech (Pasadena, CA, USA), December 2014

2 Overview ü What is the NIDIS Drought Portal, GEO/WMO linkages ü How the Portal is being used to support the Global Drought Monitor (GDM) ü How the Portal can support the Global Drought Information System (GDIS)

3 National Integrated Drought Information System (NIDIS) Goals & Objectives ü The NIDIS Act Public Law ( , December 2006), reauthorization PL (2014) better informed and more timely drought-related decisions leading to reduced impacts and costs Goal: Enable the USA to move from a reactive to a more proactive approach to managing drought risks and impacts (PL ) 3

4 The NIDIS U.S. Drought Portal ( Ø Service-oriented architecture Ø GIS interface for spatial overlays Ø Data & metadata services Ø OGC-Compliant Web mapping services Key Clearinghouse Functions: Credible, Accessible, Timely Information Where are drought conditions now? Does this event look like other events? How is the drought affecting me? Will the drought continue? Where can I go for help?

5 North American Drought Monitor (NADM) Web Services ü NADM housed NIDIS Drought Portal environment to provide OGCcompliant interactive web services ü NADM indicators overlay and analysis with NADM map boundaries using various visualization tools ü NADM indicator station, divisional, and gridded (from LBPD) data in relational data base for efficient access & analysis & interoperability between various projects & applications

6 ü The growing problem of drought and its impact on long-term sustainability of Earth s water resources has been recognized for many years. At a 2007 GEO Ministerial Summit, the event concluded with a U.S. proposal that technical representatives from participating countries build upon existing programs to work toward establishing a Global Drought Early Warning System (GDEWS) within the coming decade to provide: A system of systems for data & information sharing, communication, & capacity building to take on the growing worldwide threat of drought Regular drought warning assessments issued as frequently as possible with increased frequency during a crisis

7 Use NIDIS Drought Portal as IT Foundation for Clearinghouse for International Drought Information and Services ü Global Drought Assessment Workshop, April 2010, Asheville, NC, USA ü Workshop on the Development of an Experimental Global Drought Information System (GDIS), April 2012, Frascati, Italy ü With a web-services-based Global Drought Monitor Clearinghouse foundation (Global Drought Monitoring web portal), a GDEWS could be constructed atop it by integrating continental and regional Drought Monitors & services.

8 Global Drought Monitoring Conceptual Framework An Integration of Continental / Regional Drought Monitors NOAA s 8

9 NADM Global Drought Monitor European Drought Observatory African Drought Monitoring Centers, Princeton University Australian Bureau National of Meteorology Climatic Data Center

10 Missing Drought Information and Services ü Australia q Info from Australia s The Monitor was included in the GDM Interactive Map Viewer, but is not available now ü Africa Global Drought Monitor Ø Monthly rainfall percentiles Ø 3-Month rainfall percentiles Ø Soil moisture (2 layers) q ICPAC Flood and Drought Monitor information no longer available (no longer updated by provider)

11 GDM Current Conditions ü Grown to the 3 rd most hit page across all of drought.gov Simple assessment with a few impacts from NDMC Overview of conditions through various drought and indicator maps

12 GDM Current Conditions ü Currently 5 global drought indicators: q SPI computed from GPCC gridded precipitation q 1-month, 2-month, 3-month SPI from GHCN-Monthly station data q NOAA VHI ü Can have more (up to ~10) q GDIS community needs to agree on which products to use

13 Global Drought Information System (GDIS) IT Conceptual Framework Components ü Use a similar bottom-up approach for developing the GDIS as is used for the GDM Drought Monitoring GDM Drought Forecasting WCRP (CPC) Drought Research Drought Catalogue Drought Catalogue Drought Education Liaison with Decision-Makers & Managers for Drought Mitigation Drought Management

14 GDIS Components ü Drought Monitoring Global Drought Monitor ( Where is drought now ) ü Drought Forecasting CPC & other forecasting agencies under auspices of WCRP ( Where will drought happen in the future ) ü Drought Research case studies and other drought research to develop national & international collaborations to study the mechanisms and predictability of high profile drought and heat wave events ( Why does drought happen ) q Drought Catalogue ü Drought Education outreach component ( What is the GDIS, What do you do, etc.) ü Drought Management GDIS not involved directly in management, but provide access to tools (drought preparation plans, recovery plans, etc.) for decision-makers & managers to use to manage resources for drought mitigation if they choose ( What can we do to recover from drought, mitigate drought impacts, prepare for drought )

15 GDIS Components ü Each component is developed and functions in the most effective and appropriate manner for that component Ø Drought Monitoring bottom-up approach where each region contributes to GDM, moderate number of overarching global monitoring products and brief monthly narrative Ø Drought Forecasting perhaps top-down approach where global forecast is made of drought-related variables, and local/regional authorities translate that into a local/regional drought forecast GDIS forecasting community needs to decide on (1) which models to use, (2) who runs them, (3) who & how to interpret output (possibly need national interpreters)

16 GDIS Components (cont.) ü Each component is developed and functions in the most effective and appropriate manner for that component (cont.) Ø Drought Research collaboration amongst local/national/ regional participants Ø Drought Education outreach by participants Ø Drought Management tools are made available for decision-makers & managers to use

17 GDIS Components IT Linkages to GDIS ü Each component is developed separately ü Linkage to GDIS Drought Portal Options: 1. Component IT is developed to OGC specifications for direct linkage to GDIS and use Portal web services (e.g., map viewer, time series, etc.) 2. Component is not OGC-compliant (not interactive, just display static products/images) 3. Links to data stores (e.g., netcdf or ascii files) 4. Other ü For Forecasting Component: NIDIS Portal can incorporate model output through NOMADS archival system (e.g., CFS model forecasts) Forecast Component model output can go through NOMADS for it to utilize Portal web services (need archive agreement with NOMADS) Or, Portal could just grab forecast product (e.g., still picture)

19 OGC Compliant Web Services ü OGC Open Geospatial Consortium standards for geospatial content and services, GIS data processing, and data sharing Ø International industry consortium of 507 companies, government agencies and universities participating in a consensus process to develop publicly available interface standards. Ø OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services and mainstream IT. Ø The standards empower technology developers to make complex spatial information and services accessible and useful with all kinds of applications. Ø Standards for catalogue services, processing services, encodings, data services, web mapping services, coordinate reference systems, others
