Fifth EUMETSAT ROM SAF user workshop on Applications of GPS radio occultation measurements
ECMWF, UK, 16-18 June 2014
ECMWF hosted the Fifth EUMETSAT ROM SAF user workshop on Applications of GPS radio occultation measurements, on June 16-18, 2014.GPS radio occultation (GPS-RO) measurements are now an important component of the global observing system, because they complement the information provided by satellite radiances. This workshop, jointly organized by ECMWF and the EUMETSAT Radio Occultation Meteorology Satellite Application Facility (ROM-SAF), will review the use of the GPS-RO data at the major NWP centres, and explore how the assimilation of the measurements can be improved using more sophisticated observation operators. The value of GPS-RO as "anchor measurements" for estimating both the bias correction of satellite radiances and the model error term in "weak constraint" 4D-Var will be emphasised. The workshop will explore the potential new applications of monthly-mean and seasonal GPS-RO climatologies in NWP/climate model development and testing. The latest work on climate monitoring with GPS-RO will be reviewed.
