Hi Manus, re: > I am sorry to ask such a simple question, but I am taking a course in a > remote sensing class; though I do not come from a technical background.

A quick check of the CSU/CIRA website you reference shows that the images you are interested in are from NOAA-15/-16/-17 and are in McIDAS AREA format: AMSU swath data are availble by anonymous ftp: NOAA 15 NOAA 16 NOAA 17 The data are single-orbit McIDAS areas. (Click here for a format description.) The file names have the format starttime_endtime_NOAAnn_AMSUi.ext where starttime and endtime have the format YYDDDHHMMSS: > When I open the McIDAS-X software, there is a GUI > and a command window, but I do not know how I can load my data to plot.

The answer to your question is a bit longer than you might think since it includes the need to know how to: 1) create an ADDE dataset in McIDAS for the image(s) you download 2) an understanding of to run the McIDAS IMGDISP command 3) an understanding of image enhancement tables to colorize the images All three of these topics are covered in the Unidata McIDAS-X Learning Guide: http://www.unidata.ucar.edu/software/mcidas/2006/mclearn/toc.html and the Unidata McIDAS-X Training Workshop: http://www.unidata.ucar.edu/software/mcidas/2006/workshop/toc.html These two references are the best place to learn about running the IMGDISP command and use of the EU command to colorize images. They are also the best place to learn about creating an ADDE dataset, but I can give you a very quick HOWTO here: - first, download the image(s) that you want to use to an isolated directory where you have write permission. To make the discussion simple, let's assume that this is your McIDAS working directory and that your HOME directory is /home/user. In this scenario, the directory in question will be /home/user/mcidas/data - next, from the McIDAS-X Text and Command Window, run the following command to create a dataset from the image(s) you downloaded: DSSERVE ADD CIRA/AMSU AREA DIRFILE=/home/user/mcidas/data/*AMSUA.* "AMSU images from CIRA - next, verify that you created the dataset by listing out the images using the IMGLIST command: IMGLIST CIRA/AMSU.ALL If everything went correctly, you should get a listing of the image(s) in your newly created dataset. Next (assuming that everything was correct up to this point), display one of the images: IMGDISP CIRA/AMSU.1 EU=IMAGE This should work, but I would suspect that the colorization of the image would not be what you might expect. The other thing that you could do is to "point" at the ADDE server on the CSU/CIRA server. This is outlined in the 'Mapped Data' link off of the CIRA website you referenced. Once you hae clicked on the Mapped Data link, you will see text that looks like: Mapped Data Disclaimer Mapped AMSU data are availble two ways: * with ADDE (a McIDAS data transfer facility) * by ftp When you click on the ADDE link, you will go to a page that begins with: ADDE Mapped Data Disclaimer Mapped AMSU data are availble with ADDE (a McIDAS data transfer facility) as follows: First Set up your McIDAS or RAMSDIS. Type DATALOC ADD ULY 129.82.108.178 If this command doesn't work, either you don't have ADDE set up correctly or there is a firewall problem. You need to do this step only once. Work through the directions on this page. In particular, you should take a look at and possibly download enhancements referenced in: Third Apply an enhancement table. For product n, use enhancement AMSUn.ET EU RES AMSUn (Click here for ftp access to these files.) Once your McIDAS session is pointed at the CSU/CIRA ADDE server, you can tell your McIDAS GUI (if it is the SSEC GUI) to rebuild its server table. Once this is finished, your session should be able to access and display the images available through the CSU/CIRA ADDE server. > Thank you so much for your help, No worries.
