wrf-suews's Issues

SCM for WRF-SUEWS

@sunt05 I just tried to run a very very simple case (just a simple homogeneous domain) for SCM of the coupled version, and it seems it is working! Although it is a very simple case, but it seems promising.

Problem with Compiling WRF 4.0

I am having a problem for initial compilation of WRF. I suspect that since we are using Intel compiler, but NetCDF uses PGI. Do you have any idea? Here is the error I get:

**The following indicate the compilers selected to build the WRF system
Serial Fortran compiler (mostly for tool generation):

which: no pgf90 in (/apps/intel/2016.1/compilers_and_libraries/linux/mpi/intel64/bin:/apps/intel/2015.0.090/composer_xe_2015.0.090/bin/intel64:/apps/intel/2015.0.090/composer_xe_2015.0.090/debugger/gdb/intel64_mic/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/platform_mpi/bin:/apps/lsf/9.1/linux2.6-glibc2.3-x86_64/bin:/apps/lsf/9.1/linux2.6-glibc2.3-x86_64/etc:/home/users/homidvar/bin)

Meeting Today 21 June

Note: this post is edit by TS to reorganise the issues

  • Paper (WRF-SUEWS London/Swindon) --> in progress

  • Licence --> transfer to SUEWS

  • WRF-SUEWS for Reading? (simple Grass surface?) Maybe testing Reading with SUEWS offline by Shui (testing g1-6) --> transfer to Shui's MSc project

  • Land cover fraction for Shanghai area

    • --> set up a Shanghai project
      --> new issue under Shanghai project
  • Offline test of Shanghai (FX)- what kinds of crops? --> new issue under Shanghai project

  • WRF-SUEWS London: comparing results with and without using landcover fraction (different time of the year)- To show we need a solution to get landcover fraction better (other places)

    --> Hamid'd proposal

  • Pavement to building devision?? (maybe ask people in Sri Lanka) Tandem-X

    --> potentially related to the above one

  • Write a paper about WRF-SUEWS Shanghai

    --> new issue under Shanghai project

Problem with Qn calculations over London

@sunt05 I opened this issue to discuss about the problem we are having with new runs over London. I outputted the radiation components from SUEWS, and it is compiling now. I will run it , and will keep you posted here. If you get any new opinion what could be the source of problem (except Lup), please let me know

Key questions to think about before we start

I think there are two major questions we need to answer: (1) Which direction SUEWS should move to: a full-function land surface model or a empirical/(or semi-empirical UCM model) ?

Then question (2) If the answer is the first one, what is the potential performance for SUEWS to simulate for different land covers (like bare soil, cropland, shrubs, forests), if the second one, what the benefits SUEWS has than other UCMs (currently we have Kusaka-Chen UCM, Martilli BEM and BEP, Oleson’s CLM-U and maybe in very near future the SSIB-urban) and how SUEWS should work with the specific LSMs

Issue for calculation of qn, qf

In order to get more familiar with WPS and the process, I am trying to run a case for Colombo, Sri Lanka. I changed all the variables accordingly, and was able to start the WRF run for this case (I reduced the resolution as well). However, It seems I am encountering a problem related to calculation of qn and qf for 3rd domain, which I suspect it is related to high resolution fact.

fatal error in SUEWS:Bad input for OHM/AnOHM storage heat flux calculation. Check qn, qn_Sn, qf for issues

@sunt05 can you please tell me more about these variables?

add REGISTRY terms

add REGISTRY terms according to requirement of SuMin
design IO scheme for SuMin (namelist? SUEWS-compatible look-up tables?)
modify slab (or other scheme) to create a suitable container for SuMin

possible inconsistency in preprocessing of `wrfinput`

Something that we have not fixed yet and I think it is essential to fix (or justify it) in this stage is the following:

  • When changing wrfinputs for each specific area from the suitable parameters, we add SUEWS related parameters to all domains (1,2,3, or 4 in this case). For domains 3 and 4 there is no problem since we can modify them based on the specific city (London or Swindon). However, it is not clear what should we do for domain 1 and 2 and which parameters should be given to each grid in these domains.

  • So far, for example for 3 domains run of London/Swindon, the same parameters as domain 3 would be added for domains 1 and 2, and for urban related parameters (e.g. population, building height etc..), the values are scaled based on the urban fraction.

  • I know that it might not have lots of impacts on the final results as long as we put correct parameters in the smallest domain, and semi-correct ones in bigger ones, but how can we justify this is the best approach?

Runing WRF: Stack memory problem

I am writing this issue to address a problem new users might encounter when running WRF on head nodes. If you see a Segmentation fault error after a short time of running wrf.exe, there is a possibility (not always) that there is an insufficient stack memory. A possible fix for this problem is ulimit -s unlimited command.

abnormal first value in LW output

Great!
Now let's see the results of longer series.

And Let's open the abnormal first value Ldown as a separate issue to deal with later; but do plots excluding the first value of LW-related variables.

Demonstrative case for WRF-SUEWS coupled system

Let's discuss here about what we want to focus on to show the ability of WRF-SUEWS in the paper.

I think we are able to now to have a run to compare various fluxes of the model and the data for London (and potentially for Swindon).
What else do we need to talk about in the paper?

List of todos to improve the results of WRF-SUEWS

Here are what should be done based on my last discussion with Ting to improve results of WRF-SUEWS as of here:

  • Turn on Q_f in the runs. To do so, we need to correct the values of AHprofile in namelist.SUEWS.

  • OHM coefficients need to be fixed, and more realistic coefficients need to be considered.

  • We can impose better initial conditions for SUEWS by running it offline.

  • We need to release some of the fixed parameters in SUEWS to put it in namelist.suews.

First vertical point in WRF

@sunt05 :
I am a bit confused about the variable we should use for the height of first grid point.
There is Z variable in surface_driver, which is explained [here](Which of the following elevation should we use for this:
https://www.openwfm.org/wiki/How_to_interpret_WRF_variables#Location)
z_at_w is not in surface driver, but it is just staggered version of Z where velocities are stored there. I tried to look at this variables (for the lowest grid), and they change with time, and also for different domains! a little bit confusing.
There is another variable which is dz8w which is dz of velocity grids which is seems is around 50m for our setup, and does not change between domains!

add support for WRFV4

we should plan to support WRFV4 as it has been officially released.
maybe try to incorporate it as a submodule.

Grid level parameters: sensible inputs for e.g. urban fraction

For some of the parameters that are released on the grid level, we need to make sure that their value make sense for each specific grid. For example, Traffic rate cannot be same value for all the grids and should be valid for urban areas. Right now, same value goes to the wrfinputs and this leads to having a non-zero Qf everywhere in the domain. To fix this, I will implement a process that we will be able to mask urban areas and give suitable values for each grid level parameter

QF application for WRF-SUEWS

I am trying to use the high resolution data over London and population density data to run a case for London. This is to demonstrate the spatial variability of QF based on the population density variability. in the data, I can see that there are some parts of Central London with very high density such as 1400 per ha. Is this a normal value for that part?
