@jhamman
my guess is that you have an OUTVAR hanging around in your parameter file you cant see. beyond that, please ask the vic users email listserve

@wietsefranssen
@jhamman hi Joe, can you please help me with the 'system_tests.cfg'. I have never done this before. We need to change rout_stub into rout_rvic in the makefile. Thats the most difficult part for me I think. We also need to add af file like 'stehekin_parameters_01.rvic.prm.Stehekin.20150727.nc' to $test_data_dir/image/Stehekin/parameters/.
Wietse Franssen
@wietsefranssen
@jhamman btw din't look at the documentation yet. I only concentrated on the coding.
Joe Hamman
@jhamman
@wietsefranssen - the rvic parameters can go in here: https://github.com/jhamman/VIC_sample_data/tree/master/image/Stehekin/parameters (just open a pull request to that repo).
Joe Hamman
@jhamman
For the build, I think we should add command line option to the makefile make rout=rvic with a default value of rout=stub. That we will want to set here: https://github.com/UW-Hydro/VIC/blob/master/ci/image.travis#L64, try setting a environment variable like extension_options=“rout=stub” (or something like that) in one of the image driver build (https://github.com/UW-Hydro/VIC/blob/master/.travis.yml#L12). We could also create a new build for the image driver with extensions but this is fine for now.

One last thing. What if invoking the RVIC extension was a two step process. First, you have to build it e.g make rout=rvic, then you have to specify a parameter file. Your code would then check if it should run RVIC (both would have to be true).

For example, you might have a block of code that looks like this:

    // read global parameters
     vic_image_start();
     vic_image_start();

     if (options.rout) {
        // read global parameters for routing
        rout_start();   // Routing routine (extension)
    }
Just a few ideas.
Wietse Franssen
@wietsefranssen
@jhamman Can you please accept the pull request for the RVIC parameter file? This is needed to test travis with rvic enabled.
@jhamman by the way, we dont know if we configured travis correctly. Please have a look at the VIC pull request.
Wietse Franssen
@wietsefranssen
@jhamman We implemented the restart feature with rvic enabled today. The tests were satisfactory (meaning a difference of 0 discharge, between a normal run and a restart using an init_state file). We will cleanup the code and push it today or tomorrow.
Wietse Franssen
@wietsefranssen
@jhamman thank you for the hints you gave me the 9th of dec! I tried to play a bit with it (see commited code), as soon as the rvic param file is online I will play more. By the way: I don't understand your 'just a few ideas' example: why is there two times vic_image_start(); in the code?

Hi. I´m working on a climate change study, and I´m using VIC.4.2.d for this project. I would like to know whether the 12 albedo values in the "Vegetation Library File" and "Vegetation Parameter File" should represent the vegetation with or without snow in winter. Our study region is Norway, so I assume that it is important that I input the correct values into the model. Thanks for any advice.

Hi

I am working with VIC 4.0 version and using it for flood forecasting in North West Himalaya in India. The VIC model is showing the error:

  1. Maximum Energy Error
  2. Maximum Moist Error
  3. Error in vegetation file, grid cell 228 not found
    I have read the source code, read_vegparam.c . I checked for the 228 grid cell in my grid file and also in vegetation parameter file. It is present in both the files.

The code is showing that if 'vegcel' is not equal to 'gridcel', then this kind of error will come. I did not understand which two files I have to compare to check this vegcel and gridcel mentioned in the source code.

hi guys. I was wanting to run VIC model using the Stehekin data set but somehow I am not able to do it. Also, it says we have to download the source code off a git hub. I am confused about it. PS I am new to github, programming and would really appreciate any of suggestions to use VIC model.

Hello all, I'm having a bit of trouble with calibration. My monthly streamflow values are all nearly double what they should be. Divided the routing output by 2 and gave a 0.87 Effectiveness result. Any tips on which parameter I can adjust to greatly reduce this? Adjusting parameters mentioned on the calibration pages has resulted in only minimal changes to monthly discharge.

Dear All,
Dear All, I am running VIC model (VIC 4.2.c) and I found that the evapotranspiration becomes 0 a few days after precipitation is 0 which is not possible in actual case. Has anyone else faced this problem and is there any solution for it?

@Adrija1
@MuzzMuzzington_twitter Try with Ds and Ws parameter (Keeping a ratio almost 1), if you have minimized the b-inf parameter already.

Hi, everyone! I need to download the Global Meteorological Forcing Files at 0.5-Degree Resolution, but the web page ,"ftp://ftp.hydro.washington.edu/pub/global/1948/", cannot open.
Can you help me?

@hoseinsalehi
Hello to all
I run the model (VIC 4.2.d). The result is much more than the observation data.
I lowered Dsmax and Ds, and increased the depth of the soil layers, but the correlation coefficient decreases!
Can anyone help me?
Where can the problem be?
The total daily flow rate during the simulation period is 570, but the 7200 model simulates it.

Hello to all
I have run the vic model (4.2d) for my basin and I want to caliberate and validate now.
I am not getting enough material to learn about the same.
If anyone know the process, please explain me the processes.

There used to be some documentation on calibration at the old UW documentation website, but it appears to be down right now. The general procedure is to run the VIC model, route the runoff to the location of a discharge gauge, and compare the predicted discharge to the measured discharge. There are several parameters in the soil parameter file that you can adjust (Ds, Dsmax, etc.) to try to get a better match between your predictions and the measurements. You can find a description of all the parameters in the soil parameter file here: https://vic.readthedocs.io/en/master/Documentation/Definitions/#depth

Here is one example of a VIC calibration project: https://wwa.colorado.edu/climate/Wood_UTDWR_Report_2015.pdf

File conversions question:

Does anyone know of a tool for converting ASCII input files for VIC 4.2 to the NetCDF format needed for VIC 5's image driver? I have tried tonic (https://github.com/UW-Hydro/tonic), but it seems to still be in development. Specifically, I would like to convert the meteorological forcing files.
