1 WRF modelling of Flight B989 20th Oct 2016
WRF initialised with 0.5 degree NCEP GFS analyses 33 tracers added (see below) Simulation start (and tracer release): 06Z 20th Oct. Simulation end time: 0Z 21st Oct. 400 m resolution, 50 vertical levels. Underlying orography is USGS 30 arc-second. [SRTM or equivalent??] Run on ARCHER 512 processors ~ real time

2 Tracer locations All (?) 33 volcanoes (active and dormant) in Iceland, from Evgenia:

3 Actual WRF domain Orography contours every 50 m Volcanoes 1-33 (Evgenia’s numbering system)

4 Results Output is every 30 mins (can change to any desired frequency (subject to disk space…) Plots on the following levels: 30 m, 95 m, 186 m, 303 m, 450 m, 1094 m (can change) CURRENTLY plots are for tracer concentration at levels above ground level (can change)

5 Results contd. Concentrations are arbitrary and all plots are normalised so that the highest concentration in EACH plot is 1 arbitrary unit N.B. plots for 06Z show no tracer as this is the “moment” of tracer release.

22 14Z Direction ~ 175° 16Z Direction ~ 165°

23 tr_15, 14Z

24 Results for 08Z, 10Z, 12Z, 14Z, 16Z are online (1230 plots!)
and subdirectories. Filenames e.g. trac_all_0030_ _06:00:00 all volcanoes level (m AGL) date time (GMT) i.e. summation trac_01_0030_ _06:00:00 volcano number 01

25 Next? Extract concentration along flight path (all ; Katla ; …?) This is quite a time-consuming interpolation… Suggestions for times / Runs welcome
