ES / Salinity
Contains the salinity value of the water at the transducer head
(ES-command). This value may be a manual setting or a reading
from a conductivity sensor.
Scaling: LSD = 1 part per thousand; Range = 0 to 40 ppt
53-56
27,28
ET / Temperature Contains the temperature of the water at the transducer head
(ET-command). This value may be a manual setting or a reading
from a temperature sensor.
Scaling: LSD = 0.01 degree; Range = -5.00 to +40.00 degrees

RTC Century
These fields contain the time from the Sentinel V’s Y2K compliant
real-time clock (RTC) that the current data ensemble began. The
TT-command (Set Real-Time Clock) initially sets the clock. The
Sentinel V does account for leap years.
