binary data format

[Smita B]

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 ,lat,log are non linear values:

        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 is  a 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           tb2         date
87.809998   6.700000   500.000000   161.089996   90.379997  22102000
89.230003   6.400000   500.000000   159.869995   90.180000   22102000
86.870003   25.709999  500.000000   260.489990   243.809998   22102000
85.300003   25.400000  500.000000   258.839996   240.649994   22102000
83.730003   25.100000   500.000000   262.769989   246.820007   22102000

The grads plots I get is covering whole globe inspite of lat ,logs
confined to indian region,and frankly output i get is junk.

plz can u tell me,IS this the right way in which ASCI structure(meanin how
binary data shuld look like when converted frm asci to binary) shuld look
like.Basing on tht ill convert the same structure 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 somethins wrong in the way i am takin
the binary 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.
