  1. The Development of the Global Drought Monitor Portal and Summary of the April 2010 Global Drought Assessment Workshop Richard R. Heim Jr., Michael J. Brewer NOAA/NESDIS/National Climatic Data Center Asheville, North Carolina, USA Will Pozzi Group on Earth Observations (GEO) Architectural Implementation Pilot (AIP) Drought Working Group Lead NASA Global Drought Monitoring Workshop Silver Spring, MD – 11-12 April 2011

  2. Outline • Background • North American Drought Monitor (NADM) • Need for a Global Drought Early Warning System (GDEWS) • Summary of the April 2010 Asheville, NC, USA Global Drought Assessment Workshop • NIDIS – U.S. National Integrated Drought Information System • Global Drought Monitor Web Portal (GDMP) • Design and functionality -- GDMP as a conceptual “floor” or foundation for a GDEWS “building” • Global drought indicators • Integration of continental/regional Drought Monitors with capability to “drill down” to sub-regional, national, and local drought products

  3. Background – North American Drought Monitor • Agreement in principle between U.S., Canada, & Mexico to establish climate extremes monitoring partnership, beginning with continental drought monitor • Lead author coordinates & prepares monthly continental map & narrative • The national depictions (US, CN, MX) are prepared independently by experts within each country • NOAA, USDA, NDMC, AAFC, MSC, SMN http://www.ncdc.noaa.gov/oa/climate/monitoring/drought/nadm/index.html • Drought indices covering entire continent are needed – Continental Drought Indicators • Same indices, same analysis period, same methodologies • SPI, Palmer Drought Indices, Percent of Long-term Average Precip • Standardizing period is 1951-2001 • This consistency needed for depiction across international boundaries

  4. NADM Continental Drought Indicators • Other indicators from other sources are also used • NOAA/NESDIS Satellite Vegetation Health Index • NOAA/CPC Leaky Bucket Soil Moisture Percentiles

  5. National Integrated Drought Information System (NIDIS) Goals & Objectives Goal:Enable the Nation to move from a reactive to a more proactive approach to managing drought risks and impacts (PL109-430) The NIDIS Act Public Law (109-430, December 2006) “better informed and more timely drought-related decisions leading to reduced impacts and costs” 5

  6. The NIDIS U.S. Drought Portal (www.drought.gov) • Service-oriented architecture • GIS interface for spatial overlays • Data & metadata services • OGC-Compliant Web mapping services 1. 2. 3. 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? Portlets (DIR shown). Another example: NWS River Forecast Center Ohio River Water Resources Outlook- Ecosystem recovery

  7. NADM – Web Services • NADM web site – transitioning to interactive web site with OGC web services (within NIDIS Drought Portal environment) • NADM indicators – overlay and analysis with NADM map boundaries using various visualization tools http://www.drought.gov/portal/server.pt/community/nadm/303 Station Indicator Data NADM shapefiles Location of Indicator Stations • NADM indicator station, divisional, and gridded (from LBPD) data in relational data base for efficient access & analysis & interoperability between various projects & applications

  8. NADM – Web Services

  9. 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

  10. Drought monitoring, assessment, response, mitigation, adaptation, and early warning systems have been created in a number of countries around the world, and some regional and continental efforts have been successful … • … but a GDEWS remains elusive. • Faces hurdles that include technical, data, observation network, communications, administrative, and political issues across international borders. • How to solve these problems? • Build a foundation first – an international Clearinghouse for drought information upon which the GDEWS could be constructed.

  11. Global Drought Assessment Workshop 21-22 April 2010, Asheville, NC, USA • Gathering of international drought experts from across the world • Addressed two subjects: • Develop Recommendations to the WMO of specific characteristics of the Standardized Precipitation Index (SPI) (e.g., standardizing base period, time scales, probability distribution functions) that should be adopted by the National Meteorological and Hydrological Services around the world, as well as where this information should be integrated and hosted • Develop Recommendations for the creation of a Clearinghouse for international drought information and services

  12. Global Drought Assessment Workshop SPI Recommendations • Two options: • Compare SPI across space (e.g., within and between countries) • Best description of drought at a given location • Probability Distribution Function (pdf): • Across space—Incomplete gamma distribution • Best description—The pdf that best describes the station’s precipitation data • Standardizing Period: • Across space—At least 30 years, preferably 50 years common period (i.e., 1961-2010, or 1981-2010 if data not available from all of 1961-2010) • Best description—Entire period of record for station • Time Scales: • 1 month, 2 months, 3 months, & 6 months for meteorological drought • Computed by each Member country • Appropriate time scale depends on season, location, climatology

  13. Global Drought Assessment Workshop Clearinghouse for International Drought Information and Services Recommendations • Breakout groups discussed: • What pieces should be part of an international Clearinghouse • How should the Clearinghouse be housed, portrayed, and distributed • One suggestion was to use the NIDIS Drought Portal. • With a web-services-based Clearinghouse foundation (Global Drought Monitoring web portal), a GDEWS could be constructed atop it by integrating continental and regional Drought Monitors.

  14. A GDEWS Conceptual Framework – An Integration of Continental / Regional Drought Monitors GDMP – Global Drought Monitor Portal

  15. Continental / Regional Drought Monitors

  16. Global Drought Monitor Portal (GDMP) http://www.drought.gov/portal/server.pt/community/global_drought • Provide a web-services-based environment for: • Integration of Regional or Continental Drought Monitor(s) • Computation and display of spatially consistent drought indicators on a global scale – in situ (station) SPI, satellite-based indices, modeled soil moisture • Support for Drought Mitigation, Preparedness, & Response • Drought Education, Research, & Forecasting Tools & Products

  17. Global Drought Monitor Portal http://www.drought.gov/portal/server.pt/community/global_drought North American Drought Monitor European Drought Observatory Princeton University African Drought Monitor Participating Continents Current Global Drought Conditions – University College London

  18. Global Drought Monitor Portal Drill-down capabilities to access national to local products

  19. Global Drought Monitor Portal How the IT Functions • The GDMP is made interoperable with the GEO Global Earth Observation System of Systems (GEOSS) • by utilizing Open Geospatial Consortium (OGC) Web Mapping Services (WMS) and other web services • to exchange drought maps (and other information) among existing continental and regional drought monitoring efforts .

  20. In summary, the GDMP is a new tool that: • provides global drought indicator information, • provides an infrastructure which can be populated with drought information originating from nations across the world, and • provides data and web services capabilities for display and analysis of climatic & hydrologic data originating from participating nations; thus it • provides crucial support for drought monitoring and mitigation in semi-arid regions and other parts of the world, and • serves as a foundation for the creation of a GDEWS.

  21. How Can NASA Contribute? • Provide satellite-based global drought indicators • Provide global modeled drought indicators (soil moisture, ET, etc. • Other?
