Weather forecasting for a Swiss science expedition

This summer Greenland Guidance initiated a new service: expedition weather forecasting. Especially important for expeditions taking place in remote regions where internet access is virtually impossible. Three scientists from the University of Fribourg camped on the ice sheet while investigating meltwater in snow. We sent them detailed weather forecasts that they received on their Iridium satellite phone each morning before breakfast. We included reports on longterm stability and/or storms approaching so they could plan their activities accordingly.

The forecasts turned out particularly relevant when the team was trying to charter a helicopter for their departure, but cloud fields were causing frequent white-out conditions during which helicopters can’t fly. At an earlier date we warned them for heavy snowfall and strong winds for their location, which is extremely rare in July.

Heavy snow accumulation during the team’s expedition recorded by a nearby PROMICE weather station. 15 cm is a lot of snow for this location in summer!

Upon safe return, we received useful feedback from the field party, allowing us to finetune our Iridium messaging forecast service. The team was pleased with the accuracy of the forecasts and reported “they were very valuable and helpful!”
