Abstract

Turbulence data for the International Turbulence Comparison Experiment (ITCE) held at Conargo, N.S.W. (35° 18′ S., 145° 10′ E.) during October, 1976 are analysed.

  1. (1)

    Instrumental response at high frequencies.

     
  2. (2)

    Flow distortion induced by instruments and supporting structures.

     
  3. (3)

    Spatial separation of instruments used for covariance measurements.

     
  4. (4)

    Statistical errors associated with single point measurements over a finite averaging time, and with lateral separation of two sensor arrays being compared.
