Thank you Dr
Thanks prof
Thanks for the playlist. Could you kindly provide the documents?
It’s on my atmosfera.usm.my website.
Why did I still go wrong by following each step
Did you try using Ubuntu 18 instead of the latest version OS?
Thank you for your videos.But when I write this command(./build.roms.sh -j 2),my machine occurs a lot of problems(mkdir: cannot create directory ‘/Build_romsG’: Permission denied and ake: *** No rule to make target '/Build_romsG/netcdf.mod', needed by '/Build_romsG/MakeDepend'. Stop.)I can't solve them.Thank you so much
and I try to install the make
You have to check your permisssions. Maybe it is in a root folder that you are not allowed to use.
I understand the pain in installing of basemap.😄🥲
Yes, the prerequisites are many.
❤😂🎉😢😢😮😅😅
🎉🎉😂😅😊

Thank you for your helpful videos. when I write this command (cp ~/roms/trunk/ROMS/External/varinfo.dat .) my machine cannot find it from my truck (cp: cannot stat ‘/home/rbadpa/roms/trunk/ROMS/External/varinfo.dat’: No such file or directory), I search for it but also I couldn't find it. I tried different Linux machines, but I received this error again. I check the directory carefully. there is no variinfo.dat in the ~/roms/trunk/ROMS/External. Thnk you so much
Hi, I had it problem, i think that is for type of archive. Is diferent, .yaml i was working with .yaml is that's ok, but dont know if is correct compilar with .yaml
Excuse me, how did, you had some solution to problem?
Yes, I haven’t worked on it for some time but I think the extension changed to something else other than .dat.
It's very useful to us, because of I am the meteorology student,sir I have found one doubt sir what is pop sir, should be explain briefly sir
What do you mean by “pop?”
Well Explained 👏, Thank you
Thanks!
Dr, I want to ask a question. Do you have any suggestions for me to understand this subject more deeply?
You can read the Boundary-Layer Meteorology book by Stull.
Very helpful video, Thanks Dr
You are welcome!
Thanks Dr. Yusri, Really helpful. much appreciated.
Thanks for the comment.
Thank you sir for making this. After finished the compiling , the terminal only shows the ROMS Version and the date when I executed the model. I wonder if there is something I missed, thanks.
I’m not quite sure. If you can see the version it means that it is installed.
Hi Dr. Yusup - there used to be an introductory video on how to run AERSCREEN. I watched that a couple of months ago, however, I cannot find that video anymore on your channel. Would be interested in watching the video again. Thanks.
Hi. Thanks for you interest. Send me an email and I will forward you the link.
I am trying to compile the upwelling case and I got this error message: [proxy:0:0@localhost.localdomain] HYDU_create_process (utils/launch/launch.c:73): execvp error on file romsM (No such file or directory). Any idea ??
The error message appears when I write the command "mpirun -np 4 romsM roms_upwelling.in"
@@mapo601 Hello, disable all the MPI headers on the build_roms.cs file, if u r using revision 11 do not use gcc7.
I’m sorry but I didn’t face this before. Maybe something to do with the file name romsM?
Hi, with the FREE Format grid properties the orthogonality ERROR is to high (is in red in your example), how that error affect the result of the model? I read in the manual that changing the max range you can avoid grid problems.
The velocity was unrealistic at some domain edges but the model eventually blew up at longer run times.
I am PhD student at Umaine. I really appreciate your videos, they have been very helpful for me. I am trying to compile the UPWELLIN case, but when ROMS tries to create the file called roms.G, I got this error: cannot find libasan_preinit.o: No such file or directory. Any idea ???
Thanks for the message. Like the error said, it can’t find the file. So my first guess is that the path pointing to the file is incorrect or not updated in the make settings file. I know my answer is general because I don’t know your configuration, but it should give you a hint in solving it.
libasan is a library located in lib /LIB, r u using Mac? o linux?, this example works fine if you compile the code using the same software, like gfortran-7, gcc-7,n-c, all loaded on the ubuntu 20.04 version repository. Ubuntu 22 LTS use a different kernel, and different repository, if you install gfortran will install g-fortran 11 with is incompatible with the lib, etc...so make sure u r using the same software and the same ROMS revision 1052. For revision 11, g-fortran 7 did not work with the files .ylm, so you need to update to g-11 or compile with ifort, and more and more details....If you wanna run the code easily, install ubuntu 18 LTS and download the revision 1052.
Hi @@cl4udioiturra, thank you for your comment. I wanted to let you know that I was able to solve my problem by following this tutorial: ruclips.net/video/afcGwBWlVhE/видео.html . It is about how to install COAWST in Centos 7, COAWST is a numerical model which uses ROMS so the complementary software is the same, so I could install ROMS on Centos 7 by following that tutorial. Just in case someone else is sticky in that part.
Hi I too got the same error could you kindly tell me how to resolve it
Dear Yusri, Thank you so much for the videos. Can I ask you if installing pyroms via git and conda works in the same way that the demonstrated in the video? Im interested in generate a basic model of inertial oscillations with ROMS, mostly forced by wind. I will appreciate any suggestion. Thanks and take care.
Thanks for the comment. However, I can’t answer on whether what you suggest will work or not because we haven’t tried it ourselves. Good luck though!
Hi thanks for this...but I don't understand how to access lessons in the repository. I don't see swc file types I see "R", "yaml"...is there a tutorial on this?
You can download it manually from any github page that has a SWC file. An SWC file is the swirl course file. Try googling for some sample lessons.
@@YusriYusup Hi thanks but on the repository on swirl there are folders and no SWC files, folders titled "data analysis etc I just can seem to know what to do with them?
@@MrMenace3210 Here is a link that has some SWC samples: github.com/yusriy/R_swirl/tree/master/Courses
@@YusriYusup I am very grateful for you taking the time to help me, seriously. I can see some .swc files here - but that makes me wonder what are al of the .R files for on the learning space? how are they used with swirl?
@@YusriYusup For example the course R programming E is already installed on swirl so I can easily run it. But the folders for that course on the link you sent contain "customTest.R" and "lesson.yaml"
I have radiosonde temperature data upto 30 km. h=bo +b1QBO +b2ENSO +b3SSN +b4IOD, how can I get bo,b1,b2,b3 and b4? thank you
Thanks for the message but I don’t have experience working with radiosonde data. You could try to use multivariable linear regression fitting on the data and get the coefficients from the results because the regression would provide those constants.
how can I calculate the least square and mean squared error from multivariable regression?
I don’t know from the top of my head because I don’t memorize the functions, but the specific functions to calculate them should be built in MATLAB.
Very interesting AP Dr Yusri
Thank you!
Remove the NA and odd values from the vector V passed as the function parameter.plz code for this question
Thanks for the video suggestion but I’m not sure when I will get around to creating one. However, you can try to use an if statement in the function to search for these values, but you would need to use a for loop too. Not the most efficient code but it works.
Thanks
Welcome!

You’re welcome!

Welcome.
Excellent lecture!! Thank you so much.
You are welcome!
yes, I am watching your video for some 5th or some time, bhae. Why does this looks to me like a wittily written movie version of installing something like ROMS, you go installing stuff with a linux that doesn't have the obvious packages... and then feels like,,,poof its not gonna install.. something is bad.... and you make it work...mahn. 😂 I love how everything fell into place with you, and the person's guidance. I'm really happy for the happy ending, occuring in mere 48 mins. Never have I ever seen someone install something in such a less time, following instructions and calm... i'm used to shouting/hearing others shout if the installation seems to be not in the right path. thanks for the great video.😍👍👍🤘
Haha, thanks for the great comment!
If you r using UBUNTU 18 LTS, should have the same package library! Under 20.04 (20.02 IS THE SAME AS 18)the kernel was updated and the package library r not the same. If you wanna run the same example, use Fortran and netcdf 7, both under ubuntu 18 LTS!
at 30:33, yusriy declares that the first entered command svn isn't necessary, but in the document you've provided, it's still there. It's astounding to see making same mistake again. SO, is it necessary or unnecessary. I presume, that this was some kinda last moment prepped discussion, sorry, but atleast modify the document provided in the link. thanks.
The svn command is repetitive, but it won’t disrupt the general flow of installation. So, we felt that there is no harm in just leaving it in. At most, you just have to delete the additional folder.
@@YusriYusup thanks for the info. Though it was hauling and not to forget, Litt bit confusing with two directories.. copying, one inside other etc..anyway. it was very informative watch.
I'm having issue with the varinfo.dat file copying, I manually checked there is no such file in the ROMS/External directory.
instead i have a varinfo.yaml file
I think the ROMS developer changed the default varinfo file type to yaml. You can try to simply replace the dat file with the yaml file.
@@YusriYusup haa. I have proceeded assuming that.. and it worked.
@@ranjankumarsahu998 HI! If after running the example you have a memory leak ERROR, you have to update your gcc, gcc7 did not work ok with .yaml files.
Which website I go for start i doesn't understand
There’s a lot of websites for help, so I can’t recommend any particular one. I think you can start by reading the read me doc.
Thanks for your video! It help me a lot. But I need doc file, sometime I can't hear clearing or maybe all the time....😂 So I hope you can upload the doc file that I can understand clearly. Thank you!
Please see the video description for the link.
@@YusriYusup Thanks!
hello im talking about new directory., how can one organize the folder structure?
Just place the files into the new folders and open a new project in there.
hello teacher, what about when use the first directory? Any , this case is clear, thank you and God bless you
I don’t quite understand your question, but if you have an existing folder, you can rearrange the contents into the new folder and create a project in the new folder.
please could you send me code for 3 D (thank you lot)
Thank you sooo much for the video, I will appreciate some help here...my eta and xi variables in the gridbulder are 20 x10, but when I run de roms this error appears NETCDF_CHECK_DIM - inconsistent size of dimension: xi_rho 10
I am not sure but sometimes roms will create an additional cell for the border. You can check for those.
@@YusriYusup Thanks Yusri
Do you have a copy of the data set you used?
Hi, the data is built-in MATLAB.
@@YusriYusup Thanks very much.
Sorry can I ask one more question? Why did you use mldivide in calculating b1?
@@davidbarnwelljr103 because we want to get the slope. We use the left divide to solve the simultaneous equations in the form of a matrix to calculate it.
@@YusriYusup Ahh, thanks.. but in the second b. The b in which the y intercept is not zero. Why is this value thw y intercept, 1.427120171726537? While this value, 0.000001256394274 is the slope? I'm still trying to figure that and the purpose of the ones vector?
Hello sir, can this program be installed on Windows? Thank you
Nope, it can only be installed on Linux. You can also use the Windows Subsystem for Linux to run it.
@@YusriYusup thank you sir
Can you make one for Mac OS Monterey!?
It should be the same method for all versions of OS.
If all instructors were like you, learning would be as simple as saying good morning because you do not skip the smallest step in explaining processes. Great job!
Thank you for being to the point
