// This is a fixed-point station with dependent variables 
// measured by sensors at different heights.  Z constant for a given sensor.
// All sensors are sampling at the same time. 
//    (1) x and y and sensor-specific z are repeated for each time.
//    (2) Assign z dimension equal to number of z levels 
//    (3) Assign values for z levels in the data section
//    (4) Use variable attribute called "z" under dependent variable to 
//             associate specific z of point measurment
//    (5) Use z variable to describe all the required attributes
//             without having to repeat under each dependent variable
