Re: TEMPO Level 2 "xtrack" and "mirror_step" dimensions
The “xtrack” dimension denotes the North-South direction in fixed 2,048 step intervals. This variable correlates approximately to the latitude coordinate. The “mirror_step” dimension denotes the East-West direction and can vary by granule (for nominal operations, there are typically 131 or 132 mirror steps per granule). This variable correlates approximately to the longitude coordinate.
