5th COPS Workshop
Main Objectives
- Add supplemental NRT GPS stations in France for real time assimilation at a regional scale (50 km spacing between GPS).
- Densify the transect between all supersites for tomographic inversions (pixel size: 10 km in horizontal and 500m in vertical).
- Dense instrumentation from the valleys to the crest to measure orographic moisture fluxes and convergences.
- IASI retrievals of moisture validation
6 NRT + 16 non-NRT French GPS installed for the 3 months of the COPS field experiment

To be done before June:
- Site survey for the french GPS in Germany (a German speaking help is welcome!)
- Coordination with other ground networks (Flux, Mesonet, Sodar)
- NRT communication and data processing tests
- Installation of the GPS stations in late May.
