We report high fidelity observations of the spatial and thermal structure of an individual cloud at high resolution (20 m) over DOE’s SGP site using DOE’s MTI satellite. These observations are compared with simulations using LANL’s new cloud resolving LES model with bulk microphysics whose dynamics is constrained by soundings at ARM’s Oklahoma site. We find that our simulations capture the shape, size, altitude and thermal gradients observed by the satellite. We identify spatio-temporal distribution of thermals as the key model parameter that leads to this agreement, and use ground based concomitant collocated micropulse Lidar measurements to constrain this.
This poster will be displayed at the ARM Science Team Meeting.
