<div dir="ltr"><br>If you really want the orbital data, rather than a higher level gridded product, I'm pretty sure that you need an intermediate step to put the swath(s) in a grid that grads is friendly with. For MODIS L2 swaths, I used hdflook (on linux) to save lat-lon grids from the swaths. However it was very cumbersome, and you would not want to do that with large amounts of data. <br>
<br>I haven't seen grads open swaths (and the other replies confirm that), but I might make use of such a utility. So, you need an HDF tool, for the PC that will open swath, and write a grid. That grid would go into PCgrads.<br>

<div>Hello, </div>
<div> </div>
<div>I am trying to create plots derived from the TRMM 2A12 orbital product (it's the hydrometeor profile data) . It's not gridded data, but rather in orbital swaths. The files are HDF files, so that's why I thought that GrADS might be able to open them. However, I wasn't sure if the HDF files needed to be converted into a GrADS type file (like a .ctl file and the corresponding .dat file). I was told that the files could be converted through the following link: <a href="http://disc2.nascom.nasa.gov/data/TRMM/" rel="nofollow" target="_blank"><span>http://disc2.nascom.nasa.gov/data/TRMM/</span></a>; however I don't see anywhere on the website where this is possible. Thanks in advance for any help that can be provided.</div>
