Temperature is measured by several instruments, but only aanderaa and sbe1603do needs any further processing.
Water temperature from the Aanderaa Instruments current meter (aanderaa buffer) is NOT reported in degrees celsius. Rather, the data comes back in engineering units that must be calibrated differently for each aanderaa. These coefficients must be applied against the raw temperature sensor readings (N) for each observation via a quartic expression
A + BN + CN2 + DN3
Raw temperature counts, temperature_counts
Calibration coefficients. These are stored in the realtime NetCDF file as the attribute temperature:calibration_coeffs
None
aanderaa_temperature.m. Consult the appendix for the implementation.
