Temperature is measured by several instruments, but only aanderaa and sbe1603do needs any further processing.
Water temperature from the SBE 16-03 (sbe1603do buffer) is NOT reported in degrees celsius. Rather, the data comes back in engineering units that must be calibrated differently for each sbe1603do. First the raw counts are calibrated into "temperature frequency", and then into temperature itself.
Raw temperature counts, temperature_counts
Calibration coefficients. These are stored in the realtime NetCDF file as attributes of temperature. There are actually two sets of coefficients, one for the IPTS_68 standard, and one for the ITS-90 standard. We use IPTS_68. The coefficients are
| IPTS_68_A |
| IPTS_68_B |
| IPTS_68_C |
| IPTS_68_D |
| IPTS_68_F0 |
None
