Thank you to all those who have already submitted responses to the NWP SAF 1D-Var user survey. If you haven’t been able to respond to the survey yet, there is still time to provide your input. In order to give everyone a chance to take part, the survey will remain open until Friday 24 April. This is a good opportunity to have your say about the future development of the 1D-Var code. As a reminder, the link to the survey is: https://www.surveymonkey.co.uk/r/DJSZ3QC
