To assess the user satisfaction with the TIGGE/TIGGE-LAM archives and the quality of the service provided by ECMWF, a survey was issued on 26 November 2018 to 3,791 users who had registered to access (but not necessarily retrieved) the data. The survey was open for a few weeks, during which 10.3% (383) of invitees responded.
Initial survey results have been summarised and presented at the Workshop on Predictability, dynamics and applications research using the TIGGE and S2S ensembles (see e.g. "The technical development of the TIGGE and S2S databases"). A full survey report is also available.
