The two nested domains have 9 km resolution with 82x82 grid points and 3 km resolution with 109x109 grid points. The final domain is identical to the model (CAMx) master domain, with a 1 km resolution generated by <a href="/MANUALS/AIRWARE/MM5toCAMx.html">MM5toCAMx</a>:</p> <p>Central coordinates for mother (largest) outer model domain are: 51.24°E, 35.67°N The projection used in MM5 computations is Lambert-Conformal projection. The MM5 model output is converted to a UTM grid after the model run using MM5toCAMx postprocessing program.</p> <p>Vertical resolution of the model domain consists of 17 levels plus surface (1000 mb). The model has a high vertical resolution near the surface to cover layering used by CAMx. The vertical levels are distributed as follows (in mb): 1000, 997, 994, 988, 976, 940, 883, 850, 780, 700, 600, 500, 400, 300, 250, 200, 150, 100.</p> <p>The computational time step for the largest domain is 81 s. The timestepping increases by factor 3 for nested domains. Approximately 3 times horizontal grid resolution in km. Model output frequency is 1 h.</p> <p>Integration time of the model is 2+24 hours for three consecutive days.</p> <p>MM5 data (except precipitation and cloud water) are calculated from midnight to midnight next day in local time, 00:00 local time till 24:00 local time, all together included = 25 timesteps. Last timestep (24:00 local time) is overwritten with the next day forecast (00:00). Precipitation and cloud water data have 24 timesteps from 00:00 local time till 23:00 local time.</p> <p>There is also one version starting at 18:00 UTC and finishing at 24:00 UTC next day = 30 hours. The first 2 hours "startup" are discarded, that means it would import data from 20:00 UTC or midnight local time. The simulation finishes at 24:00 UTC or 3:00 local time next day. The last 3 hours are redundant, but they are necessary for historical scenarios because boundary conditions are only available at 24:00 UTC. FNL data don't have output at 21:00 and the model needs boundary conditions for the whole duration.<br> The last timestep imported is 21:00 UTC or midnight next day local time. Last 3 hours are not used.</p> <p>Starting at 18:00 UTC and finishing at 21:00 UTC next day = 27 hours. 25 hours from local midnight to midnight next day.</p> <p>The toal forecast peropd displayed is 3*24 (72 hours) without any overlapping.</p> <p>The model setup takes into account the local time shift from UTC of 4 h (not 3.5 hours). Start time of forecast simulation is at 18:00 UTC "today" and end time of forecast simulation is 24:00 UTC "tomorrow".
