Sample exercise data products processed and produced in ‘real-time’ by exercise participants. a The top panel shows surface displacement from day 1 to day 3 from GPS (black arrows) and InSAR (acquired on day 2). The middle panel shows the modelled displacement (Bagnardi and Hooper 2018) and the bottom panel shows the residual for the InSAR data, as well as a comparison of GPS data-model using black and red arrows respectively. The data reveals a deflation signal caused by a shallow source that is located at ~ 2500 +/− 200 m depth, centred beneath Katla, according to the best model solution. b Cumulative tephra deposit as computed by the VOL-CALPUFF model (Barsotti et al. 2008). The contours show the tephra loading in kg/m2 at the end of the eruption. c Students at the University of Iceland testing new ASH-SIZER instruments (Marchetti et al. 2014) in Reykjavik during the exercise. The instruments were streamed in real-time to both UI and IMO. d Estimate of the mass eruption rate (MER) made using the PlumeRise model (Woodhouse et al. 2016). e Range of MER estimates from the REFIR integrated system (Dürig et al. 2018)
