Read particular band from air temperature image among MOD07 air products [message #54457]

Goodday, Everyone! I would like to ask how to process MODIS 07 air
product.

I am working on 3D-MOD07 image. As most of you may know, the dimension
of this file is, at least in my knowledge....

sample number(ns): 270, Line number(nl): 406, 그리고 band number(nb): 20

In order to get the map of band20, I wrote a source code below, but
this procedure is not working properly.

-----------------------------
pro test
close, /all
ns = 270
nl = 406
nb =20
file = 'MOD072003001.0130_Ta_5km.img'
openr, 1, file

image = bytarr(ns, nl, nb)
readu, 1, image
close, 1

tvscl, image(*, *, 19)

end

-----------------------
In my opinion, there must be something wrong at this line shown
below...

"image = bytarr(ns, nl, nb)"

However, I don't know how to solve this problem... I tried read_jpg,
and read_gif instead of bytarr, but all of these trials were not so
successful.

Please give me any suggestions. Thanks.

Harry
