Variables in CASES97 5-Minute and 30-Minute Data Sets

[an error occurred while processing this directive] For some variables, the sensor name is appended, e.g. "v.csat" is the lateral velocity component from the Campbell Scientific sonic anemometer (only at station #8), to distinquish it from "v" which is the same variable measured by the default sensor at each station (either an ATI or Gill sonic anemometer).
