We offer the capability to download multiple days of non-ASCII OMI data files in one package. The largest number of files that will be packaged in one download is 14 days worth of files, or approximately 196 files. You also have the option to choose a span of days, and then when the files are presented, you may choose only selected files at particular hours of your interest by unchecking the box to the left of each file offered in your date span.
