He is currently working on improving mesoscale weather prediction models for improving monitoring and forecasting of high-impact weather.   Dr Dinand Scheppers: After finishing his BSc and MSc from Delft University he has worked as a research intern at the SRON Institute for Space Research in the Netherlands and at Wuhan University GNSS Research Centre in China. He then went on to study for his PhD at SRON and is now working at ECMWF on the ERA-CLIM2 climate reanalysis project

WG1 Deliverables Year 1 Year 2 Year 3 Year 4 Support for establishment of new GNSS ACs, to cover gaps within Europe X Develop new multi-GNSS processing algorithms (GPS+GLONASS+Galileo ready) in collaboration with the IGS and EUREF working groups GNSS processing Workshop on 1) GPS and GLONASS processing and 2) assessment of new GNSS tropospheric products (gradients, slant delays, etc). Develop tropospheric models based on NWP data for enhancing real-time GNSS processing in close collaboration with WG2 Develop new operational GNSS tropospheric products (gradients, slant delays, 3D water vapour and refractivity by tomographic reconstruction) in close coordination with WG2

WG2 Deliverables Year 1 Year 2 Year 3 Year 4 Establish database of obs. and products for severe weather case studies X Evaluation of data quality of GNSS processing algorithms including GLONASS Evaluation of new operational GNSS tropospheric products (gradients, slant delays, 3D tomography) based on selected test cases in collaboration with WG1 GNSS nowcasting workshop on tools and practices for monitoring and forecasting severe weather QC of the operational GNSS tropospheric products delivered by the new ACs Develop/fine tune and test methods for initialisation of NWP models with the new GNSS troposheric products Test impact of new operational GNSS troposheric products for selected severe weather cases Development of operational tools for severe weather forecasting, in collaboration with E-GVAP and EUCOS.

WG3 Deliverables Year 1 Year 2 Year 3 Year 4 Detect and mitigate discontinuities in the ZTD and IWV time series. X GNSS climate Workshop on climate trends and variability of water vapour on regional and global scales. Exploit reprocessed GNSS tropospheric products for evaluation of NWP reanalysis products, in collaboration with WG2 (e.g. ERA-Interim, MERRA, CFSR) and climate models simulations (e.g. IPCC-AR5, CORDEX) in collaboration with climate community. Development of relevant diagnostics and indexes for quantifying climate trends and variability.
