The following IMET sensors were installed and in use during ACCE.
| Type | Model |
|---|---|
| Air temperature | IMET Alden 7030-A and ORG-715(ScTi) |
| Barometric pressure | (AIR) |
| Precipitation | ORG-715(ScTi) |
| Relative humidity | IMET (Alden 7030-A) |
| Sea Surface Temperature | Seabird |
| Short Wave Radiation | Eppley PSP |
| Wind Speed and Direction | Bendix |
Data: The data were logged to ASCII text files, one containing ship navigational information, and the other containing meteorological information. Molly Baringer (AOML) has complete copies of these data.
Observed problems with underway systems:
1) Humidity sensor- an unknown problem occurred that resulted in the temporary loss of humidity readings for a short time
2) Network problems- resulting in the halting of collection on the centralized computer.
3) Depth recording- occasionally the CHIRP II system would lose the automated lock on the bottom, due to an increase in the time variable gain. The depths thus recorded are unrealistically shallow. At this time there is no known way to correct or flag these bad values. Other segments of data were lost when the output to the CIDS was turned off (the default configuration). This would occur inadvertently whenever the computer systems were rebooted.
4) During heavy seas the TSG system pumps air and must be shut down. In addition, the TSG calibration appeared to drift fresh during the cruise. Methods to clean the system must be developed.
