| Standard Profile Spacing | 5° longitude x 5° latitude, and 1-km vertical resolution; programmable to other modes and resolutions |
| Swath | Typically six profiles across 2,000-to-3,000-km-wide swath |
| Spatial Resolution | Profile spacing 500 x 500 km horizontally (equivalent to 5° long x 5° lat) x 1 km vertically; averaging volume for each data sample 1 km vertical x 10 km across x 300 km along line-of-sight |
| Mass | 220 kg |
| Duty Cycle | 100% |
| Power | 220 W (average), 239 W (peak) |
| Data rate | 65 kbps |
