Name Units
Ux m·s -1 Wind speed along sonic x-axis
Uy m·s -1 Wind speed along sonic y-axis
Uz m·s -1 Wind speed along sonic z-axis
deg
T_SONIC Sonic temperature
C
diag_sonic none Raw sonic diagnostic value (0 indicates no diagnostic flags set)
volt_KH20 mV Raw signal voltage from KH20
Diagnostic value from KH20 (a non-zero result indicates
diag_KH20 none volt_KH20 was returned as not a number, less than -10 mV, or
greater than 4500 mV).
PA kPa Ambient pressure
deg
TA_1_1_1 Air temperature measured by the temp/RH probe

RH_1_1_1 % Relative humidity measured by the temp/RH probe
deg
FW Air temperature measured by fine-wire thermocouple

TABLE C-16 through TABLE
in each data output table and when each data field is included in the table.
Prior to coordinate rotations, the orthogonal wind components
from the sonic anemometer are denoted as U
Following coordinate rotations, the common denotation of u, v,
and w is used, respectively.
Variables with _R denote that the value was computed after
coordinate rotations were done. Variables with a _F denote that
the value was calculated after frequency corrections were applied.
Similarly, _SND and _WPL refer to variables that have had the
SND correction or the WPL correction applied, respectively.
