Units
decimal degrees Solar elevation
decimal degrees Solar hour angle
decimal degrees Solar declination
Air mass coefficient: Ratio of the
none path length between the current solar
position to the solar noon
Day time in fraction of an output
fraction
interval
Average temperature of targeted
deg C
object
deg C Average temperature of sensor body
Average soil temperature for each
sensor; x is an index for the number
of sensors. If both TCAV and CS65X
deg C
used, this data field defaults to
TCAV, and C65X data is stored in
TS_CS65X_x_1_1.
Average volumetric soil water
m 3 ·m -3 content for each CS650 or CS655; x
is an index for the number of sensors.
Average soil temperature from
deg C CS65X probe; x is an index for the
number of sensors.
Average electrical conductivity for
each sensor; x is an index for the
dS·m -1
number of CS650 or CS655
Average soil heat flux at plate; x is an
W·m -2 index for the number of HFP01 or
HFP01SC
Average heat flux at ground surface;
x is an index for each soil sensor suite
W·m -2 replicate (suite includes soil
temperature, soil water content, and
soil heat flux)
Heat flux manifested as heat storage
in layer between heat flux plate and
W m -2 soil surface; x is an index for the
number of soil temp and water
content sensor pairs.
Distance upwind where the maximum
m
contribution to the footprint is found
Upwind distance that contains 90%
m
of cumulative footprint
