Hi, I am modeling the San Francisco Bay-Delta an estuary with several
tributaries including the Sacramento River, San Joaquin River and numerous
smaller streams. The boundary data are time series of cross-sectional velocity
profiles across each channel. The cross-sections for different sensors are
different and each cross-section contains numerous points.
I would like to retain the information about which velocities come from which
sensors, and also add some attributes about the sensors. Can anyone comment on
which of these possibilities is best:
1. Each sensor is an independent file. Then the variable would be
water_velocity_x and _y, the transect locations would be included as a
coordinate and the sensor station name such as sacramento_rsac075 would be an
attribute. It is unclear to me that there is a standard nomenclature for the
sensor name.
2. Each variable is a sensor station-variable pair:
sacramento_rsac075_velocity. I don't see anything that looks like this in the
CF examples, but the standard does not address variable names. I would use an
attribute to identify the sensor name redundantly, and again I am not clear if
there is a standard for this. The hitch seems to be that each station would
have a different set of cross-section locations so the file would have a
location coordinate for each sensor.
3.The data could be velocity(time,station). The "station" coordinate would be
associated with lat, long and sensor names. This lumps all the data in one
variable. The sensor used for each data point can be identified, but there is
no clear slot for sensor metadata.
Thanks,
Eli
