The IEM processes GINI formatted GOES satellite imagery into more accessible PNG files and maintains an archive of these processed files. A problem was discovered with the archive of these images since 18 March 2015. The PNG files were saved as 16 bit unsigned ints instead of 8 bit. This causes the image to be 'blank' for most applications that view PNG images, but not for many GIS software packages which is why I did not immediately notice the troubles!

Anyway, a process is now running to repair these files and I'll update this news item once completed.

Update 9 AM 6 Oct: The repair script has completed. Please let us know if you encounter bad data.
