Hi Michele,
I ordered some MSG IODC data from EUMETSAT from 05/09/2018 (times 12:00, 12:15, 12:30, and 12:45). I was able to successfully create dust RGBs using the dust RGB formula from the RGB-Eumetsat plugin. If you aren't using this method, you can install the plugin by opening the Plugin Manager (Tools>Plugins>Manage from the Main Display) and click the green Install Plugin button next to Miscellaneous > RGB-Eumetsat. I loaded my data via a local ADDE dataset. Once I was in the Field Selector, I chose the "SEVIRI RGB > Dust" derived field, the "3 Color (RGB) Image" display type, clicked the green arrow button in the Advanced tab of the Field Selector to get the full domain at full resolution and clicked Create Display.
I have a few questions for you: [list=1]
Does my process above, using the SEVIRI RGB Dust formula, match what you're doing? If not, could you please give me a step-by-step process for how you're attempting to create your RGB? The dust RGB makes use of 3 IR bands (8.7, 10.8, and 12.0 microns) to create the RGB. I've seen cases in the past when attempting to create RGBs where some of the bands I selected didn't contain any data at my selected location, and therefore weren't included in the RGB output. I'm curious if this may be the case here, since it sounds like only the red component (8.7um) is being displayed. Could you please verify that all 3 of these bands include data at the location you're creating your RGB? You can verify this by creating a simple Image Display of each band. What platform are you running on? When you say "the latest version of McIDAS-V", do you mean the last stable release (1.7u1) or one of our nightly builds (1.8beta1)? You can find this information by selecting "Help>About McIDAS-V" from the Main Display. If none of the above points help to solve the problem, it may be useful for me to get a sample of your data. Perhaps you could tar up a directory of data and post it to our ftp? Here are instructions for doing that (from a command prompt or terminal window): ftp ftp.ssec.wisc.edu user: anonymous password: your_email_address bin cd pub/incoming put filename bye ... where filename is the name of your zipped/tarred directory. Could you please let me know the file's name if/when you post it?
Thanks, Bob Carp McIDAS Help Desk
