Each meteorological station must measure meteorological parameters within the range specified below and at the accuracy and resolution specified below. The ranges, accuracies, and resolutions specified below do not apply if that particular model of meteorological station is not designed to measure that particular parameter, as long as the vendor is able to provide at least three models that fulfill the requirements listed in section A. 1) Wind speed. Range: 0 to 60 m/s. Accuracy: 0 to 10 m/s: 0.3 m/s root-mean-square error. 10 to 40 m/s: 3% root-mean-square error. 40 to 60 m/s: 5% root-mean square error. Resolution: 0.01 m/s; 2) Wind direction. Range: 0 to 360°. Accuracy: 0.5 to 40 m/s: ±3°. 40 to 60 m/s: ±5°. Resolution: 1°; 3) Air temperature. Range: -35°C to +70°C. Accuracy: ±0.3°. Resolution: 0.1°C...
