Manuscript on the evaluation of moisture from NWP models with the advanced geostationary imager measurements published: A manuscript titled "Evaluation of Environmental Moisture from NWP Models with Measurements from Advanced Geostationary Satellite Imager—A Case Study" has been published in Remote Sensing (2020, 12(4), 670; https://doi.org/10.3390/rs12040670). Three numerical weather prediction (NWP) models—Global Forecast System (GFS), Unified Model (UM), Weather Research and Forecasting (WRF), are evaluated with brightness temperature (BT) measurements from the three moisture channels of Advanced Himawari Imager (AHI) onboard the Himawari-8 satellite. It is found that the three NWP models have similar performance for lower tropospheric moisture, and GFS has a smaller bias for middle tropospheric moisture. In addition, there is a close relationship between moisture forecasts in the environment and the tropical cyclone (TC) track forecasts in GFS. When the infrared and microwave sounder radiance measurements from polar orbit satellite are assimilated in regional WRF, it is clearly shown that the environment moisture fields are improved compared with that with only conventional data are assimilated. Coauthors are Xiaowei Jiang (CMA and AOS/UW-Madison), and Jun Li (CIMSS, the corresponding author) et al. (Jun Li, Jun.Li@ssec.wisc.edu, 608-262-3755)
