Introduction
The TIGGE(global) archive consists of global ensemble forecasts from 11 NWP centres, starting from October 2006. The TIGGE-LAM is an extension of TIGGE archive to include ensemble weather forecasts from 7 limited area models (LAM), starting from January 2013. The data can be retrieved directly from the web interface or programmatically via a Web-API.
To assess the user satisfaction with the TIGGE/TIGGE-LAM archives and the quality of the service provided by ECMWF, a user survey was issued on 26 November 2018. The invitation was sent to 3,791 users who had registered to access (but not necessarily retrieved) the data. The survey was open for few weeks, during which 10.3% (383) of invitees responded.
