JULES 4.7 Northern Hemisphere Animations
Sample JULES4.7 Northern Hemisphere Land Surface Processes Simulation
(by Patrick McGuire, Pier Luigi Vidale, Alberto Martinez de la Torre and Grenville Lister)
- Monthly Average Precipitation, used as one of the WFDEI driving factors
- Monthly Average Total Soil Moisture, one of the outputs of the JULES simulation
- Monthly Average Net Primary Production (NPP), one of the outputs of the JULES simulation
These animations were produced from the Rose/Cylc suite u-ar428 with JULES4.9 (with 0.5 hour time steps) that dumped the data to disk every 6 hours of simulation calendar time, by using:
i) a CSH script (see below) that uses CDO to do the monthly averaging for the 11 year data set, which creates a new NETCDF file;
ii) the interactive software, Panoply (version 4.8.5), that uses the new monthly-averages NETCDF file and saves the PNG animation frames to disk (the MP4 export option didn’t work); and
iii) this ImageMagick command to merge the PNG frames into an animated GIF:
convert -set delay 0 -colors 256 -dispose 1 -loop 1 precip*.png precip_1979_1989.gif
