NSF/NCAR C-130Q Hercules (N130AR)
Aerosol Racks - ADS Sample Table
NOTES: | 1. RDMA setup - same as EPIC |
2. Nephs serial is free running, about 2Hz. How to sample? | |
3. Climet serial output looks weird. | |
4. Inlet ident - can we rig up and log a 3-position switch ? | |
5. CN counter #1 = same as always. CN #2 has flow but no temperature or pressure. |
