Hi, Zilore ?
There is some documentation on plotting station models at http://cola.gmu.edu/grads/gadoc/usingstationdata.html#model, which has some tips in there regarding what happens when some data values are missing. Also, try changing ?set dignum? to increase the number of significant digits.

Subject: [EXTERNAL] [gradsusr] Plotting station data in Grads

I did find a solution to write binary station data using gfortran, which, if may help someone else is:
access="stream" in place of recordtype="stream".
however I need help to understand the following:
Firstly I attach the station data which was written to binary (and two plots from that data). When I display the data with:
set gxout model
d u;v;t;d;slp,0.0.cld,wx,vis
Only the wind is displayed correctly. Only the first letter is displayed for temperature, dew point temp and pressure.. The cld, wx and vis variables seem. to be unused. When I multiply every variable by 10 (except for wind), temperature, dew point and pressure display correctly but missing values, set to -99, display as -9.
I am using Grads-1.8SL11.fedora on Centos 6.7. I have difficulty installing newer versions of Grads.
I have used station data before and have never experienced this problem. I will appreciate any assistance.

Thank you Jennifer,
My question was really to find out:
1. Why I have to multiply by 10 to have temperature,dew point and pressure.
I have used this for years and I do not remember multiplying by 10.
2. Why visibility and present weather, visibility and clouds are not
plotted.
Am I right to suspect that the gfortran compile is not good enough for this?

Subject: [gradsusr] Help Regarding additon of extra t dimension ina grd file
Message-ID: <002801d5ab57$0561af10$10250d30$@barc.gov.in>

Dear GrADS users,

I have a file grd file (also having netcdf file) of t dimension varying from 1 to 120.

Now I want to make a file of t dimension of  1 to (120+12= )132.

The first 12 data which I am going to add is just the repetition of  second 12 data in new file. (or saying in another way, I want to repeat the first 12 data of old file in t dimension to make new file with total 120+12=132 t dimension)

 

Any idea regarding this using GrADS will be appreciable.

Thank you in advance of reading my problem.

Dear Tanmoy
I don't think it's easier in grads and consequently it is problematic
to write multi-timestep netcdf file in grads. However, it's very easy
to implement using cdo (as you told you have corresponding netcdf
file). The procedure will be the following:
Lets suppose you first file name (that having 12 timestep) is file120.nc. Then
cdo seltimestep,1/12 file120.nc first12.nc
cdo mergetime file120.nc first12.nc file132.nc

Now, file132.nc will contain 132 timesteps where first 120 timesteps
will be from file120.nc (original) and rest 12 timestep will be from
first12.nc (first 12 timestep of file120.nc).

I hope it will solve your problem.

Cheers!!!!!!

Dear Sir,
Thank you so much for your reply. I have used this option. It is creating merged *.nc file. But that merged file is not opening using GrADS. It is giving some error saying "time unit has too small and increment".
Don?t know why I am not able to visualize. That why I am confused.

Hi Tanmay,
I've addressed before by writing a ncap script (http://nco.sourceforge.net/nco.html)to convert the time increment to a larger value. I don't have access to my files right now, but I can post an example later.

Dear Tammy
Is it possible for you to share your netcdf file? If the sige is big then
cut it to a smaller domain by cdo sellonlatbox.
I will check it and reply accordingly.

I don't think Suman's CDO solution may not work.
cdo mergetime file120.nc first12.nc file132.nc

first12.nc's timesteps are the part of file120.nc, so in the cdo mergetime
output may not write the same timesteps twice. Therefore, the file132.nc
may have only 120 timesteps; however, I may be wrong as well.

Thank you Kishore. You are correct. The year of the file first12 should be
changed using cdo settime and settaxis. After that only mergetime will work.

I don't think Suman's CDO solution may not work.

cdo mergetime file120.nc <http://file120.nc/>  first12.nc <http://first12.nc/>  file132.nc <http://file132.nc/>

Dear Tanmoy
I don't think it's easier in grads and consequently it is problematic to write multi-timestep netcdf file in grads. However, it's very easy to implement using cdo (as you told you have corresponding netcdf file). The procedure will be the following:
Lets suppose you first file name (that having 12 timestep) is file120.nc. Then cdo seltimestep,1/12 file120.nc first12.nc cdo mergetime file120.nc first12.nc file132.nc

I hope it will solve your problem.

Ok sir,

Sorry for delayed reply. I missed your mail. This is nothing but our NCAP simulation files. You can take any sector *.nc file for any species.

I have one more Idea, that I am going to try.

I will convert the files to *.grd(grads format) then for first 12 timestep I will write another *.grd file. Then I will merge two file (new one and the old one) using cat command in Linux.

I will try and let you know.

The option what I mentioned earlier is working well.

Thanks

Ok sir,

Sorry for delayed reply. I missed your mail. This is nothing but our NCAP simulation files. You can take any sector *.nc file for any species.

I have one more Idea, that I am going to try.

I will convert the files to *.grd(grads format) then for first 12 timestep I will write another *.grd file. Then I will merge two file (new one and the old one) using cat command in Linux.

I will try and let you know.

Dear Tammy

Is it possible for you to share your netcdf file? If the sige is big then cut it to a smaller domain by cdo sellonlatbox.

I will check it and reply accordingly.

Dear Sir,
Thank you so much for your reply. I have used this option. It is creating merged *.nc file. But that merged file is not opening using GrADS. It is giving some error saying "time unit has too small and increment".
Don?t know why I am not able to visualize. That why I am confused.

Dear Tanmoy
I don't think it's easier in grads and consequently it is problematic to write multi-timestep netcdf file in grads. However, it's very easy to implement using cdo (as you told you have corresponding netcdf file). The procedure will be the following:
Lets suppose you first file name (that having 12 timestep) is file120.nc. Then cdo seltimestep,1/12 file120.nc first12.nc cdo mergetime file120.nc first12.nc file132.nc

Now, file132.nc will contain 132 timesteps where first 120 timesteps will be from file120.nc (original) and rest 12 timestep will be from first12.nc (first 12 timestep of file120.nc).

I hope it will solve your problem.

Cheers!!!!!!

Best
Suman

Hi Sumant,

Here?s an example of how I use the NCO utility NCAP2 to change seconds to minutes so that I can read a file in GrADS:

ncap2 -O -s "time=time/(60)" -s "time at units=\"minutes since 1979-01-01 00:00:00\"" $infile $infile # change time units

The online reference is here: http://nco.sourceforge.net/nco.html#ncap2-netCDF-Arithmetic-Processor
