Reporting of modelled data under the AQD IPR for e-reporting

Transcription

1 Reporting of modelled data under the AQD IPR for e-reporting RETROSPECTIVE OF PILOT TESTING IN 2012 & MODELLING DATA Tony Bush 6 th pilot meeting Copenhagen 8-10 October 2012

2 Introduction Where does modelled data sit within the e-reporting compliance package Scope of data type for today s discussions The IPR data requirements Proposed encoding Data reporting (delivery)

3 Modelled data within e-reporting IPR Modelled data is a form of supplementary assessment data as set out by Articles 7 and 10 of the AQD Article 4 of 4DD As for measurement methods, supplementary assessment methods need to be described Description allows methods to be identified and checked against the DQOs of the Directives Description forms part of Data flow D

4 Scope of supplementary data type The IPR provides for 3 similar supplementary assessment data types Indicative measurements Modelled data Objective estimation Indicative measurement metadata requirements map well to fixed measurements metadata profile Modelling and objective estimation data types have common metadata requirements which are subtly differ from measurements Metadata requirements for modelling and objective estimation may be grouped into a single metadata profile

5 Status of the metadata profile Data specifications established by IPR and split guidance Requirements seem to be sensible Some optimisations may be required subject to testing A workable platform to finalise the profile Wider initiatives $$$Dublin meeting will feed into the specifications and standard used

6 Assessment data types Objective estimation for an area Model observations on a irregular grid Model observations on a road network 3-dimensional model observations Model observations on a regular grid

7 Common metadata profile Data item Requirement Datatype D.7.1 Assessment ID M ID D Assessment method name M Text D Assessment method description M Text D Assessment method documentation M Text D Environmental Objective M codelist D Area of Assessment M Bounding box D Measurements used for model calibration C (M) xlink href D Measurements used for model verification C (M) xlink href or description D Model time reslution unit M codelist D Number of time units M number D Assessment period description M Text D Assessment period time unit M codelist D Number of time units M number D.7.6 Spatial resolution description M Text D DQO Uncertainty estimation C (M) number D DQO Documentation C (M) number D DQO Link to documentation report C (M) URL D Standard Databases V codelist D Other Databases V Text D Assessment method for WSS C (M) Text D Assessment method for NAT C (M) Text D.7.10 Used for compliance assessment under AQD M codelist

8 Metadata model for AQD measurement processes Comes close to the metadata requirements for supplementary assessment But, not quite there in some areas

9 Metadata model optimised for supplementary assessments Proposed solution is to extend ef:observingcapability Using ef:observingcapability data specifications where possible Extending to domain specific requirements as needed

10 Metadata model optimised for supplementary assessments Looking at the ef:observingcapability data specifications these may be reused as follows. Description Domain Time instant for the observation Localised name Unique ID Pollutant Observed feature (grid, road network, region)

11 Metadata model optimised for supplementary assessments Extending for data specs relevant to the requirements for supplementary assessments

12 Metadata model optimised for supplementary assessments Extending for data specs relevant to the requirements for supplementary assessments

13 Influence of other initiatives on modelling metadata The GEO AQ CoP Group on Earth Observation for Air Quality Community of Practice a self-organized voluntary group that fosters the application of Earth observations to air quality management and science. Workshop on Air Quality and Atmospheric Composition Metadata (Dublin, 5-7 Sept. 2012) Captured collective views on metadata (discovery, dataset, dataseries) Outcomes will be rolled into the emergent schema INSPIRE AC/MF version 3.0 community recommendations Draft schemas published July 2012 AC/MF specific content mysteriously absent from feature catalogue and SVN MOLES: Metadata Objects for Linking Environmental Sciences Developed by UK s NERC DataGrid A group documents which either provide descriptions of some key features of environmental data and their context or provide links to those descriptions.

14 AC/MF AC/MF data specifications Version Application schema for describing observations on A regular grid A trajectory A collection of points (irregular grid) Data models appropriate to core types of model outputs for air quality
