14 Drought Monitoring State of the Science: Where are we now? WCC-3,GDPN/GEOSS is a way to learn/leverage from one another Canada/Mexico/United States UN/WMO/others Many regions/countries are working together to better monitor drought Monitoring of impacts globally is virtually nonexistent Early warning/monitoring just one key: THEN WHAT? Need linkages to risk/vulnerability assessment and planning for adaptation Many indicators/indices don t reflect reality in various regions, or for various season(s) or for both!

15 Drought Monitoring State of the Science: Where are we now? Heightened awareness as a result of IPCC AR4 An explosion of good work/tools/products out there over the past 5 years Impediments remain Lack of coordination Lack of trigger ties to any drought plans Resources Lack of data/long-term data Lack of impact data/collection Lack of institutional cooperation Lack of drought mitigation plans

17 Approaches to Drought Assessment Single index or indicator (parameter) Multiple indices or indicators Composite Indicator

18 The U.S. Drought Monitor Since 1999, NOAA (CPC, NCDC, WRCC), USDA, and the NDMC have produced a weekly composite drought map with input from numerous federal and non-federal agencies Western Region Climate Center on board 2008 CalDry listserver hosted by CA DWR 10 authors in all Incorporate relevant information and products from all entities (and levels of government) dealing with drought (RCC s, SC s, federal/state agencies, etc.) (~260 experts)

19 The Drought Monitor Concept A consolidation of indices and indicators into one comprehensive national drought map Convergence of evidence approach Trying to capture these characteristics: the drought s magnitude (duration + intensity) spatial extent probability of occurrence Impacts Rates drought intensity by percentile ranks

32 Why Track Drought Impacts? Establish an impacts baseline for monitoring Climate change To know where to direct relief To reduce vulnerability in advance of the next drought Ground truth indices No single method exists for collecting and/or quantifying drought losses Very little in the way of environmental or qualitative collection

33 Some DIR Factoids Established in 2005 DIR DB now contains ~12,000 impacts 1,891 impacts added in 2009

35 Initial Remote Sensing Efforts to Support the USDM 1. Vegetation Drought Response Index (VegDRI) integrates satellitebased vegetation index (VI) observations, climate based drought index data, and general environmental information (e.g., LULC type, soils, and elevation). o NDMC and USGS Center for EROS are working to develop a MODIS based VegDRI to replace the current AVHRR VI based operational VegDRI products.

38 What is the National Land Data Assimilation System (NLDAS)? The Land Data Assimilation System (LDAS) consists of uncoupled models forced with observations, satellite data and radar precipitation measurements, and is therefore not affected by Numerical WP forcing biases. Near real-time using existing Surface Vegetation Atmosphere Transfer Schemes (SVATS) by NCEP, NASA, Princeton University, and the University of Washington at 1/8 degree (about 14 kilometer) resolution across North America and at 1/4 degree resolution globally. Outputs: soil moisture, snow water equivalent, total runoff, streamflow, evaporation and precipitation. The SM anomalies and percentiles are based on a 28 year climatology ( )

39 USDM Concept Expanded to North America The monthly North American Drought Monitor (NADM) was introduced in 2003 and built upon the USDM concept. Challenges: 1.Limited number of data inputs compared to the USDM 2.Data inconsistencies (e.g., specific measure, format, and quality) among countries 3.Currently, limited use of remote sensing-derived inputs (primarily NDVI).

40 National Integrated Drought Information System (NIDIS) A NOAA-led Federal, State, Tribal and Local Partnership (Public Law , 2006) Goal of NIDIS: Improve the nation s capacity to proactively manage droughtrelated risks by providing decision makers with the best available information and tools to assess the impact of drought and to better prepare for and mitigate the effects of drought.

41 NIDIS Implementation Team Partners (to date): Other Partners: Western Governors Association (WGA) National Drought Mitigation Center (NDMC) Regional Climate Centers American Association of State Climatologists Indigenous Waters Network Weather Channel Numerous Universities including: University of Oklahoma, University of South Carolina, University of Washington, South Dakota State University, and Cornell University.

43 Moving Forward: Scales Immediate future development in the USDP will be aimed at: Spinning up regional pilot activities and regional depiction of drought What tools are currently in place that we can leverage in the SE US and the upper Colorado Basin for purposes of mitigation of impacts and adaptation? Are tools applicable to local/regional level or are they transferable nationwide? Who are the key local/regional players? What else have we missed? Working with GEO to begin addressing global and international drought monitoring and forecasting

44 NIDIS Pilots A Geographic Framework for Developing Drought Early Warning Systems (EWS) for Local-Scale Decision Making Integrated Climate, Ecosystems, Hydrology, & Remote Sensing Info & Data NIDIS Pilot Areas + = Watershed, state, tribal, local: Experience & Knowledge Decision Support Issue-based EWS tailored to the critical decisions and issue facing each basin Each EWS will be unique with specific inputs and methods developed and implemented by local experts Partnerships between: 1) federal, state, and local agencies, 2) tribal groups, 3) other types of NGOs; and 4) private sector

45 Moving Forward: Call for Content The USDP is looking for partners to contribute the following four types of information (in priority order): Web Mapping Services (WMS) that meet the standards of the Open Geospatial Consortium (OGC) 1.0 or higher. Drought-related maps and web sites that are regularly updated and can be rendered in a USDP portlet. Drought-related maps and web sites that are regularly updated and can be made available only as a stand-alone page. Non-regularly issued reports related to drought, of a non-time sensitive nature.

46 WCC3 Executive Summary concluded: that present capabilities to provide effective climate services fall far short of meeting present, and future needs and benefits, particularly in developing countries; that the most urgent need is for much closer partnerships between the providers and users of climate services; that great scientific progress has been made especially by the World Climate Programme and its associated activities over the past 30 years, which provides already a firm basis for the delivery of a wide range of climate services; and that major new and strengthened research efforts are required to increase the time-range and skill of climate prediction through new research and modelling initiatives; and to improve the observational basis for climate prediction and services, and the availability and quality control of climate data;

47 called for major strengthening of the essential elements of a global framework for climate services: The Global Climate Observing System and all its components and associated activities; and provision of free and unrestricted exchange and access to climate data; The World Climate Research Programme, underpinned by adequate computing resources and increased interaction with other global climate relevant research initiatives. Climate services information systems taking advantage of enhanced existing national and international climate service arrangements in the delivery of products, including sectororiented information to support adaptation activities; Climate user interface mechanisms focused on building linkages and integrating information, at all levels, between the providers and users of climate services; and Efficient and enduring capacity building through education, training, and strengthened outreach and communication. supported the development of the proposed Global Framework for Climate Services.

48 What is GEOSS?: The Global Earth Observation System of Systems The Global Earth Observation System of Systems will provide decision-support tools to a wide variety of users. As with the Internet, GEOSS will be a global and flexible network of content providers allowing decision makers to access an extraordinary range of information at their desk.

51 Global Drought Preparedness Network Individually, many nations will be unable to improve their drought coping capacity. Collectively, through global, regional, and national partnerships, we can share information and experiences to reduce the impacts of drought.

52 Potential Regional Networks Southeastern and Central European Network North American Network Mediterranean Network West Asia Network Caribbean Network Asian Network South American Network Sub-Saharan African Network

53 Future Drought Monitoring Challenges The Big Five: Impact collection/quantification Soil moisture (especially in situ) Hydrology (surface and groundwater) Application of remotely sensed/modeled products operationally (trust) (operational) Ecological/Environmental (D-x E?) If a drought occurs in the desert, does anybody see it?

54 Summary Drought is not just a physical event Vulnerability matters Impacts (establish a baseline) Global DEWS: Heighten Awareness and act as a Focusing Tool for Policy Makers Planning, policy, mitigation, adaptation Promote and Encourage Citizen Science
