it includes all the input file (wrfbdy, wrffdda, wrflowinp, and wrfsfdda) for the entire year of 2016 for the base line case, a case for modifying these input with keeping 3, 4, and 5 significant digits, respectively. This dataset is not publicly accessible because: it is about 0.5TByte of data. It can be accessed through the following means: it is on EPA HPC archival system, asm (/asm1/dwong03/data_compression/wrf/input). Format: WRF input files for entire year of 2016. This dataset is associated with the following publication: Wu, S., D.C. Wong, J. Wang, Y. Jin, J. Li, and C. Lu.
