WP4 Assessment of reference data in global assimilation systems and characterisation of key satellite datasets
This workpackage is concerned with the potential utility of data-assimilation systems used in Numerical Weather Prediction (NWP) and reanalyses to use reference-quality data to make geographically broader implications about satellite-observational performance. The workpackage shall:
- Assess the performance of a number of new satellite systems using reference-quality data and data assimilation (Task 4.1).
- Develop infrastructure for near-real-time acquisition of reference-quality data (Task 4.2).
- Develop software systems to enable monitoring of reference-quality data streams using global data assimilation systems (Task 4.3).
- Develop a more general approach to use of reference-quality data in data assimilation, including for oceanic and terrestrial Essential Climate Variables (ECVs) (Task 4.4).
