🔭 Excursion to De Groene Jonker
08:00-13:00
Round off the conference with a morning in the field at De Groene Jonker, a classic Dutch wetland of reeds, open water, and wet grasslands just south of Amsterdam, and a wonderful spot for wetland birds and insects (see recent observations). We will go for a 2-hour walk on flat terrain and the tour will be guided by Hans van Gasteren and supported by other local colleagues. A small bus leaves Amstel Station (precise location t.b.d.) at 8:00 and returns around 13:00. Please bring your own food, drinks and binoculars; the organisers will bring a spotting scope to share.
Places are limited to 30 participants and allocated on a first-come, first-served basis. To help cover transport, we ask for a contribution of €25 (payment by invoice is not possible). To join, edit your registration and complete the payment. Your place is guaranteed once payment is received.
Training workshop
The pre-conference workshop will be a two-day long immersive training in the use of weather surveillance radar data for applications in aeroecology. We will cover the basics of radar remote sensing, data visualization, and data processing. Early-career professionals, practitioners, and students are encouraged to participate.
For inquiries about the workshop, please contact Kyle Horton.
