[gradsusr] Station data

[Thomas Davies]

Hi,

I am trying to plot station data recieved from UKMO datapoint. I have
written the data to a text file like this (Following the tutorial here:
http://cookbooks.opengrads.org/index.php?title=Recipe-013:_Gridding_and_Plotting_Station_Data
):

53.252 -4.537 1011 *

I wrote it in the exact same format as the link above and ran
station2modelgrid.c (using TCC compiler for windows), as well as stnmap
with this descriptor file:

*DSET ^station.dat*
*DTYPE station*
*STNMAP ^station.map*
*UNDEF -999.0*
*TITLE station data test*
*TDEF 1 linear 22Z17FEB2016 1mo*
*VARS 1*
*slp  0  99  SLP*
*ENDVARS*

However when I open station.ctl in GrADS and plot the slp variable no
values are displayed. I have tried changing the format of the text
file/C-script however nothing has worked for me.

If anybody can spot a problem or provide an alternative C script with notes
about the text file formatting (I don't know any C or Fortran)

Thanks in advance.
