Good evening CMAQ users:
I have been struggling on the MCIP during the past a few weeks. Most of the issues have been solved, and now it stuck on the generation of PURB, for which I could not find out the solution.
I used NAM to generate the WRF output file (https://nomads.ncdc.noaa.gov/data/nananl/). The MCIP output was successfully generated by the wrfout file. However, when I check the GRID_CRO_2D file generated by MCIP, the variable PURB was not generated. As a result, when I tried to run CCTM, it shows
*** ERROR ABORT in subroutine INIT_MET on PE 000 Error interpolating variable PURB from GRID_CRO_2D
(I am using CMAQ5.2, and version 4.3 for MCIP)
My questions are:
a). Is PURB required for running CCTM? Is there anyway to disable it?
b). If PURB is required, how could it be generated by MCIP? Is there some settings in MCIP or WRF to make this happen? Or it is due to the input files of WRF? How could I prepare it?
