Hi Kevin and Aubrey,
Thank you so much for your instruction. I have tried without CSV and could past the error and produced the outputs. I attached here a piece of time of CHRTOUT_GRID1 for streamflow and run log (successful one) for checking. I still have some issues:
- Upside down streamflow in QGIS, I guess it was because QGIS reads the coordinates differently as you and Aubrey helped me explained before. I will try to find more solutions as my project requires it should be read by QGIS. Please let me know if you have any solutions.
- The streamflow and TOPOGRAPHY data are not aligned in QGIS (I used the one from Fulldom_hires as attached in mataura_test_001.zip)
- When I tried on python they all align well and not upside down at all. I will use python for visualisation for temporary. Please let me know if you have any other suggestions for QGIS.
- Large values and negative values for streamflow. I guess this is because I use the forcing data from WRF model output (I changed the name into *.LDASIN_DOMAIN1, FORC_TYP=1, to be able to run the wrf-hydro), the RAINNC (unit is in mm, not mm/s or kg/m^2) is the reason making the streamflow values strange like that. If using FORC_TYP = 3, I don't know why the wrf-hydro cannot work (based on the error, it looks like the wrf-hydro cannot find out my forcing data files). I attached the WRF output after regridding (please note it is under 7zip file) and the run log error (failed one) for further reference.
For the csv file for forecast points, I tried it again with changing the points into different places. It worked this time, but the frxst_pts.tif did not show the forecast point using the <Build_Routing_Stack.py>, but when I checked by using the <Examine_Outputs_of_GIS_Preprocessor.py>, the result "frxst_pts.tif" did show it. Please help me check on this one.
The code fore Build_Routing_Stack.py is: python Build_Routing_Stack.py -i C:\Users\mng42\wrf_wps\example_nz_033_full_100m\
geo_em.d01.nc -b False -r True -d C:\Users\mng42\wrf_wps\example_nz_033_full_100m\mataura_4326.tif -R 4 -t 2000 -o C:\Users\mng42\wrf_wps\example_nz_033_full_100m\output\mataura_test_001.zip
Apart from those files attached, I also included other files - namelist.wps, hydro.namelist, and namelist.hrldas. Please let me know if you need further information.
I really appreciate for all your patience and big helps.
Kind regards
Martin Nguyen
