Evaluating the Impact of Planetary Boundary Layer, Land Surface Model, and Microphysics Parameterization Schemes on Simulated GOES-16 Water Vapor Brightness Temperatures

The impact of several land surface models (LSMs) and microphysics (MP), planetary boundary layer (PBL), schemes on the accuracy simulated brightness temperatures (BTs) from water vapor (WV) sensitive bands was examined via comparison with observations GOES-16 Advanced Baseline Imager. Nine parameterization configurations were evaluated. Analysis revealed that, compared to Thompson MP scheme, National Severe Storms Laboratory scheme produced lower WV BTs in upper troposphere but higher middle troposphere. configuration Geophysical Fluid Dynamics hybrid eddy-diffusivity mass-flux (EDMF) PBL instead Mellor–Yamada–Nakanishi–Niino (MYNN) BTs. Yet, changing MYNN Shin–Hong or EDMF reduced Changing LSM Noah RUC also resulted BTs, which further enhanced GFS. location orientation upper-level jet streams troughs assessed using gradient objects.
