Dear iEMSs Members and Friends,

You can find more information on the conference on the website here, and we will keep updating this site with all the details as they emerge. Make sure you mark your calendars for next year.

We are still calling for workshop proposals and are currently assessing all session proposals received, to put together an exciting programme for everyone. Registration for the conference and the call for abstracts will open after the summer. So please watch this space and get in touch with us if you have any thoughts or suggestions.

Please share and advertise the conference widely in your networks! We look forward to seeing you all in East Lansing next year.

Obituary: Dr James (Jim) Ascough III

A tribute in memory of Dr. James (Jim) C. Ascough II

Timothy R.Green, Olaf David, Holger R.Maier

This is a tribute to Dr. Jim Ascough, who was an enthusiastic member, officer and medalist of the International Environmental Modelling & Software Society (iEMSs). Sadly, Jim died of a heart attack on 1 December 2016. This shocked his family, friends and colleagues, who knew Jim as an active person who rarely lacked energy for any endeavor. Jim is survived by his wife, Dr. Lois Deer-Ascough (Deer-Ascough et al., 1995; Ascough et al., 1998), son TJ (age 22) and daughter Katie (age 18).

Outside of work, Jim was fully engaged as a husband and father, who expressed his love to his family in words and actions. Even during the work day, it was not uncommon to hear Jim talking on the phone to one of his kids or his wife. He was an active participant in their school and athletic activities, even coaching soccer and playing tennis with his children. The family took vacations together, attended church regularly, and participated in many outdoor activities, like hiking in the Rocky Mountains.
