Performance

Performance test in various configurations:

• for grid resolution (glevel 4,5,6: 2562, 10242, 40962 points in mesh)
• 40 vertical levels (one test with 80 vertical levels)
• iso/non-iso
• wavelength resolution r5, r50, r500 (35, 323, 3192 bins)

Noted the time taken for one step. Estimated the time to run 1500 simulation days. (one simulation step is 300s, estimated run time for 432000 steps)
