[G06-1-04] Main achievements of the Working Group 1 “Advanced GNSS Processing Techniques" of the COST Action ES1206: GNSS for Severe Weather and Climate (GNSS4SWEC)
We give an overview of WG1 activities and focusing on achievements within Benchmark and Real-time Demonstration campaigns. For the Benchmark campaign a complex data set of GNSS observations and various meteorological data were collected for May-June 2013 which included severe weather events in central Europe. An initial processing of data sets from GNSS and numerical weather models (NWM) provided independently estimated reference parameters – ZTDs and tropospheric horizontal gradients. The Benchmark data set is used for development of an optimal strategy for real-time processing and a validation of tropospheric horizontal gradients and line-of-sight tropospheric slant total delays from GNSS, NWM-raytracing and Water Vapour Radiometer solutions. Real-time campaign is used to demonstrates products achieved in operational GNSS real-time analysis.
