ARPS IHOP 4 (on Boomer) New!
3 km domain --- from 23 UTC (assimilation,
directly using Donghai's data):
* 153×103×53 grids, covering 450 km × 300 km area;
dtbig = 5s; explicit ice-phase microphysics only.
[results very similar to Donghai's using ARPS 4.5.1 and myself's
run on paige using ARPS 5.0.0Beta]
1 km domain --- 150 min simulation, starting from 2330 UTC
(without ADAS):
* 353×213×53 grids, covering 350 km × 210 km area
(60 processors are used on Boomer); dtbig = 1s; explicit ice-phase microphysics
only.
1 km domain --- 150 min simulation, starting from 2330 UTC
(with ADAS, NIDS radar only):
