STRENGTHS:-GEWEX HAS A SYSTEM FOR GENERATING GLOBAL DATA SETS:

WEAKNESSES:-CHARACTERIZATION OF ERRORS -RESOURCE CONSTRAINTS LIMITAGENCIES IN SUPPORTING THEREPROCESSING OF THESE GLOBALPRODUCTS.

GEWEX Objective #1:Produce consistent research quality data sets complete with error descriptions of the Earth's energy budget and water cycle and their variability and trends on interannual to decadal time scales, for use in climate system analysis and model development and evaluation.

GEWEX Objective #2:Enhance the understanding of and quantify how energy and water cycle processes contribute to climate feedbacks.

STRENGTHS:GEWEX THROUGH ITS FIELD PROJECTS HAS THE POTENTIAL TOOBSERVE AND ANALYZE FEEDBACK PROCESSES.

WEAKNESSES:1. GEWEX ONLY ADDRESSES SOME

FEEDBACK PROCESSES AND MUSTCONSIDER THESE IN A BROADERCONTEXT

2. GEWEX DOES NOT HAVE A CLEARMODEL PLATFORM FORSENSITIVITY EXPERIMENTS.

GEWEX Objective 3:Improve the predictive capability for key water and energy cycle variables and feedbacks through improved parameterizations to better representhydrometeorological processes, and determine the geographical and seasonal characteristics of their predictability over land areas.

STRENGTHS:1. GEWEX HAS DONE SOME WORK ON

PREDICTABILITY (GLACE, LBA) 2. GEWEX HAS CONSIDERABLE EXPERTISE

IN REGIONAL MODELING

WEAKNESSES:1. TOOLS FOR PREDICTABILITY STUDIES

NEED FURTHER DEVELOPMENT2. GEWEX DOES NOT FORMALLY DO

MODEL DEVELOPMENTIn between, soil

wetness sensitivity and conditional instability both

have some effect.Arid Humid

(KOSTER ET AL. 2004)

GEWEX Objective 4:Undertake joint activities with operational hydrometeorological services, related ESSP projects like the GWSP, and hydrological research programs to demonstrate the value of GEWEX research, data sets and tools for assessing the consequences of climate predictions and global change for water resources. STRENGTHS:1. GEWEX HAS ATTRACTED A CADRE OF EXCELLENT HYDROLOGISTS2. GEWEX HAS MANY LINKS WITH EXTERNAL HYDROLOGY

GROUPS (IAHS, UNESCO IHP, WMO HWR, ETC)

WEAKNESSES:1. FEW COUNTRIES HAVE PROGRAMMATIC LINKS

BETWEEN WEATHER AND HYDROLOGIC SERVICES.

2. GIVEN THE PREVASIVE NATURE OF USERS OF WATERINFORMATION IT HAS BEEN DIFFICULT TO SELECT THE“RIGHT” USER COMMUNITIES WITH WHICH TO WORK.

A Project of Projects

NEESPI and CEOP share an objective of better understanding of underlying energy and water cycle

processes to enhance our ability to describe the Earth Climate System and predict its changes with a particular

focus to preserve the legacy of these studies.NEESPI and CEOP efforts will feed each

other because:

• One of the NEESPI objectives is the same as CEOP’s• NEESPI has an open data policy• Rich historic in-situ data sets, modernization of

existing networks, introduction of new modern instrumentation to the NEESPI domain from the Arctic to the Central Asian and Gobi Deserts will be of help to the CEOP data collection strategy

GEWEX CONTRIBUTIONS TO IPY RELY ON NEESPI

GOAL: GEWEX SEEKS TO UNDERSTAND THE SIGNIFICANCE OF HIGHLATITUDE PROCESSES FOR THE MEASURMENT, MODLEING AND UNDERSTANDING OF THE GLOBAL ENERGY AND WATER CYCLE.

RECENT ACCOMPLISHMENTS:GEWEX HAS ADOPTED NEESPI ASA NEW RHP (FORMERLY CSE).NEESPI HAS A MAJOR IPY COMPONENTWITH USA AND RUSSIAN FUNDINGAND ADDRESSES IPY ISSUES.

PLANS:CEOP WILL ESTABLISH SOME NORTHERNREFERENCE SITES AND GEWEX WILL LAUNCH AN IPY FIELD AND MODELING STUDY OF THE EFFECTS OF AEROSOLS AT HIGH LATITUDES (DEPENDING ON FUNDING)

BALTEXTERRITORY

• Observe, simulate, and predict the diurnal, seasonal, annual and interannual cycles

• Determine climate system variability and critical feedbacks

• Demonstrate improvements in predictions of water-related climate parameters

• Demonstrate the applicability of techniques and models for other regions

• Assess the human impact on hydroclimate variations, including vulnerability to climate change

• What Pasha promised on behalf of NEESPI…..

GEWEX CSE Scientific Criteria:

GEWEX CSE Technical Criteria:• Numerical Weather Prediction Center for provision of

atmospheric and land surface data assimilation [BCC, RCC-M]• Atmospheric-hydrological models for studying transferability

and climate variability [WRF, VIC, need regional reanalysis]• Mechanism for collecting and managing adequate

hydrometeorological data sets [5 NEESPI SDS Centers]• Participate in the open international exchange of scientific

information and data [NEESPI Data Policy]• Interaction with hydrological services and related groups• Evaluation of GEWEX global data products [mutually

beneficial proposals should be written]• Contribution to CEOP in situ, remote sensing and model

output databases [collaboration already started; 2 tiers]

Summary: NEESPI has the scope, breadth of scientific endeavor, and the broad international

involvement to be an effective Regional Continental Scale study within GEWEX

• NEESPI has a completed Science Plan and a wide range of pilot funded projects. This will be supplemented with an Implementation Plan that (among other issues) will show how NEESPI addresses specific issues of relevance to GEWEX

• NEESPI has a handful of recently funded projects focused on integration; NEESPI scientists published ~120 refereed papers in the past year (including 5 books)

• NEESPI has established Science Advisory Panel (1st Meeting was held in Feb. 2006); NEESPI Coordinating and Steering Committee (NCSC; Reps. of Funding Institutions and Agencies) met at the same time and the second meeting is scheduled in Helsinki in May 3-4, 2007

• NEESPI International Coordination Office in Europe is under construction

1. Provide a framework for guiding decisions on priorities and strategies regarding water cycleobservations for:

- Monitoring climate variability and change,- Effective water management - Societal applications for resource

development and environmentalmanagement,

- initial conditions for weather and climate forecasts,- Research on priority water cycle questions

2. Promote strategies that facilitate theprocessing, archiving and distribution of watercycle data products

NEESPI ON THE GEWEX ORGANIZATION CHART

As a result of this agreement GEWEX is now trackingNEESPI progress and interacting with NEESPI scientistswhere ever appropriate to ensure that the:- NEESPI contributions to GEWEX objectives are integrated

into the GEWEX program.- NEESPI plans take into account the need for field validation

of GEWEX data products in the NEESPI region.- NEESPI scientists are aware of the data processing

capabilities of GEWEX infrastructure and take fulladvantage of these services.

- Scientists from the NEESPI region have opportunity to befully involved in all aspects of the GEWEX project.

- within its limited capabilities, GEWEX provides the supportnecessary to the development of the NEESPI program toenable its success.

-NEESPI can provide process understanding needed forparameterization of unique processes in Euroasia
