Slide 2
Why MESoR ?
Many sources for solar resource knowledge are availableEvery source has its own access mechanism and data formatQuality of the sources is often not well knownResults are difficult to compare

There is quite a number of data sources, but this creates uncertainty of the results, especially if they do not agree

Project Objectives
GuidingBenchmarking of solar radiation ProductsGuide of best practice in using solar resource knowledgeRoadmap for future research and services
UnifyingUnifying access to solar resource dataBroker portal as one stop shop

Slide 4
Guiding: Benchmarking
Collection of a reference data set of high quality ground measurements
Baseline Surface Radiation Network (BSRN)International Daylight Measurement Programme (IDMP)Global Atmospheric Watch (GAW)Other high quality measurements
Common procedure for quality control of the ground data
Common set of benchmarking measures and rules

Slide 5
Benchmarking of Time Series Products
First order measures: Bias, root mean square error, standard deviation
Sometime this match is not necessary (e.g. system layout with historical data)
Second order measures:Based on Kolmogrov-Smirnov Test

Slide 9
Development of a Roadmap
We would like to know more about what is needed in solar resources:
Which products need improvement?
Which services need improvement?
Which new products would you like to see?
Which new services would you like to see?
Which new observation instruments do we need (ground and space based) ?
Please enter your ideas in the questionnaire

Slide 10
Unifying Access
Lessons learned from SoDa:General portal is beneficial for solar energy usersSoDa used proprietary software and communication standardsHigh maintenance efforts in operating the portal
New approach in MESoR:Open source software portal with large development community Internet standard communication protocolsGoogle Maps API for ease of useThe portal is a broker for data bases located elsewhere, it does not store and offer data itselfConnexion with larger intiative (GEO/GEOSS - IEA-Task36 SHC)

Prototype Architecture – Web Services
A standard mean to expose and consume local or remote dataProviders keep the overall control of the WSWritten in Java but other languages are possible (PHP, Python...)Should be deployed on a WS compliant platform (Community Portal)Contains executable that trigger the data accessExpose a WSDL file as a bridge to interoperabilityWSDL file expose location, input/output types and operations of the Web Service
