Before you start working with the ACE data sets...

The following pages provide important background information for members of the ACE Validation Team. They describe what species and parameters the ACE instruments can measure, how they make their occultation measurements, where the ACE occultation measurements are made in latitude and some limitations in when measurements can be made.

It is also recommended that you read the overview of ACE mission by Mission Scientist Peter Bernath published in the GRL special section.
