Assessment of Product Documentation for Climate Modelling User Group
Assessment of product documentation
PURPOSE: to update the existing report (currently 3-years old)
1.
To assess project deliverable documents such as:
-
Product validation and inter-comparison Report
-
Climate Assessment Report
-
Comprehensive Error Characterisation Report
-
Others e.g. Product specification document, User requirement document
2.
Give feedback to ESA and the CCI teams:
-
Through assessment of Quality, Uncertainty, and Maturity of the product
Assessment of product documentation
Existing ECVs

For Essential Climate Variables:
Land ECVs
*new ECV
Ocean ECVs
*new ECV
Atmosphere ECVs
*new ECV
Cyrosphere ECVs
*new ECV
Assessment of product documentation
•
Quality:
Product validation and inter-comparison report (2017).
Visual quality of the SR composite from AVHRR (sufficient), PROBA-V, MERIS FR
and RR (very good)
Missing lakes, NaN in bright areas e.g. desert, cloud/snow/ice discrimination,
undetected clouds
•
Uncertainty:
Comprehensive characterisation report (2015)
•
Maturity:
Climate Assessment Report (2017)
Outcomes of assessment of various land cover products
Future opportunities for improvement of land cover maps
Assessment of product documentation
•
Quality:
Product Validation Plan (2014)
Good overview of data required for validation (point scale, global/regional, long-
term trends)
•
Uncertainty:
Comprehensive characterisation report (2017)
Error characterisation at various stages in the processing chain
•
Maturity:
Climate Assessment Report (2017)
Has been used in various applications e.g.
Relative dynamics are well captured but absolute values may differ
Assessment of product documentation
•
Quality:
Product Validation Report (2018)
Validation of the fire_cci for different sensors applied
•
Uncertainty:
Comprehensive Error Characterisation Report (2014)
Reported uncertainties are very different between products
•
Maturity:
Climate Assessment Report (2017)
Assesses the conservation of fire patch morphological features across products,
uncertainty and relationship to fire size.
Potential to increase resolution to determine fire perimeters, propagation and
ignition
Assessment of product documentation
•
Quality:
Quality Assessment Report (no PVIR)
•
Uncertainty:
Comprehensive Error Characterisation report (2017)
Error and uncertainty for: Surface Elevation Change, Glacial Mass Balance, Ice
Velocity, Grounding Line Location
•
Maturity:
Comprehensive Error Characterisation report (2017) (no CAR)
Provides some guidelines for Surface Elevation Change, Glacial Mass Balance, Ice
Velocity, Grounding Line Location
Assessment of product documentation
•
Quality:
Product Validation and Inter-comparison Report (2018)
Validation of Surface Elevation Change, Ice Velocity, Grounding Line Location,
Calving Front Location, Gravimetric Mass Balance
•
Uncertainty:
Quality Assessment Report (no CECR)
Each parameter has their own uncertainty
Grounding Line Location difficult to validate, missing values around ice sheet
margins due to steep relief
•
Maturity:
Quality Assessment Report (no CAR)
Ice Velocity, Surface Elevation Change, Gravimetric Mass Balance products applied
Future improvements should focus on investigating systematic biases
Product validation and inter-comparison report: Steps and strategies used for the validation
Climate assessment report: an assessment of trends and variability in the CCI products compared to other products
Uncertainty characterisation report: document the best current understanding of uncertainties (i.e., components of error distributions)
Product specification document: complete description of the products
User requirement document: derive the specifications
Quality: Product validation and intercomparison report, product validation report, product validation plan
Uncertainty: Comprehensive error characterisation report
Maturity: Climate assessment report, user requirement document, product specification document,
Conducting an assessment to update the existing report on project deliverable documents, including product validation, inter-comparison reports, and error characterization. Providing feedback to ESA and CCI teams on the quality, uncertainty, and maturity of the product documentation related to various Earth Climate Variables (ECVs) for the Climate Modelling User Group.
