2. CRITERIA FOR REPORTING 2.1 General When air-ground data link is used, the wind direction, wind speed, wind quality flag, temperature, turbulence and humidity included in air-reports shall be reported in accordance with the following criteria. 2.2 Wind direction The wind direction shall be reported in terms of degrees true, rounded to the nearest whole degree. 2.3 Wind speed The wind speed shall be reported in kilometres per hour or knots, rounded to the nearest 2 km/h (1 knot). The units used shall be indicated. 2.4 Wind quality flag The wind quality flag shall be reported as 0 when the roll angle is less than 5 degrees and as 1 when the roll angle is 5 degrees or more. Annex 3 — Meteorological Service for International Air Navigation Appendix 4 7/11/07 APP 4-4 2.5 Temperature The temperature shall be reported to the nearest tenth of a degree Celsius. 2.6 Turbulence The turbulence shall be reported in terms of the cube root of the eddy dissipation rate (EDR). 2.6.1 Routine air-reports The turbulence shall be reported during the en-route phase of the flight and shall refer to the 15-minute period immediately preceding the observation. Both the average and peak value of turbulence, together with the time of occurrence of the peak value to the nearest minute, shall be observed. The average and peak values shall be reported in terms of the cube root of EDR. The time of occurrence of the peak value shall be reported as indicated in Table A4-1. The turbulence shall be reported during the climb-out phase for the first 10 minutes of the flight and shall refer to the 30-second period immediately preceding the observation. The peak value of turbulence shall be observed. 2.6.2 Interpretation of the turbulence report Turbulence shall be considered:
