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.

Second

To display a product,

IMGDISP ULY/AMSU.n frame LATLON=lat lon MAG=mag GRAY=Y

where n is the product number described on the previous page

Third

Apply an enhancement table. For product n, use enhancement AMSUn.ET

EU RES AMSUn

(Click here for ftp access to these files.)

The ET and ES versions are simply big-endian and little-endian versions of the same enhancement table. Note that you must change the name of the .ES files to .ET. If you apply the enhancement and everything turns black, try the other version. It is easiest to try the .ET versions first because no renaming is necessary. The .ET files generally work on HPs, and the .ES files generally work on PCs.

The time which McIDAS displays at the bottom of the image is the time of the last line of the last orbit. All of the data displayed are before this time--within approximately 12 hours of this time, depending on how many missing orbits there are. The times of equator crossing (HHMM UTC) are "carved" into the data at the equator for easy reference.

On ulysses, the file name for product n is AREA000n or, if n>9, AREA00n. Mercator files are 14,375,768 bytes, and Polar Stereo files are 4,000,768 bytes. Using ADDE automatically decreases the number of bytes to be transferred to one screenful, approximately 300 kbyte. One can use the IMGCOPY command to transfer the entire file (SIZE=ALL).

If you use the data, please tell us how useful they are.
