format of binary data.

[smita]

Hi all,

  I am a project student at NATIONAL REMOTE SENSING AGENCY,HYD.
  I am working on a project to estimate large area soil moisture with the
data acquired by Multifrequency Scanning Microwave Radiometer (MSMR)
  In this context i would like to use GRADS.

  The data i have will be as specified in binary.I have for specific longitude and latitudes,
a group of variables tb1,tb2 being brightness values,at surface level
  for ex the binary values in asci:
  250(tb1)   228(tb2)   37.82(lat)   97.65(log) 20001022(date)
 254        226       37.04        93.78       20001022
 252        226       35.60        93.50       20001022

My question is how shuld this grads binary structure shuld look like for .ctl file to read.

  when I gave to Grads longitude,latitude,level[some const value],tb1,tb2,and date(const),this below data isa binary data,as a example how it looks like i printed values in asci here.But while giving to ctl file it reads binary data only not asci.

  lon                      lat         lev         tb1(var1)           tb2 (var2)        date
87.809998   6.700000   500.000000   161.089996   90.379997    22102000.000000
89.230003   6.400000   500.000000   159.869995   90.180000   22102000.000000
86.870003   25.709999  500.000000   260.489990   243.809998   22102000.000000
85.300003   25.400000  500.000000   258.839996   240.649994   22102000.000000
83.730003   25.100000   500.000000   262.769989   246.820007  22102000.000000

  The grad plots i get is covering whole globe instead of the lat and longitude range,in this covers only india,and frankly output i get is junk

  plz can u tell me,IS this the right way in which Asci values shuld look like.Basing on tht ill convert the same structure to binary(convert asci values to binary) and give to grads,

  Any examples,would be appreciated, or if u can correct how this asci format shuld look like.Cause i feel somethin wrong is being done in how i am inputting data.

  I also tried using station mappin I get Numbers how do i convert to plots or contours.

  Which is better to use Grads or station data mapping for land data mapping.
