"If you can predict the weather, it only takes a few more variables to predict air quality," said Robert Rohde of Berkeley Earth, a U.S.-based non-profit that maps China's real-time air pollution. "Most of the time pollutant emissions don't vary very rapidly."
“如果能够预测天气的话,只需要多添加几个变量就可以预测空气质量。”追踪中国实时空气污染分布的美国非盈利组织Berkeley Earth主管罗伯特·罗德表示,“大多数时候,污染物的排放不会在短时间内产生改变。”
But there are still kinks to work out. The latest version of Microsoft's iPhone app lacked the forecasting function advertised, which the company blamed on a bug, while during a recent "red alert," when the air was considered hazardous and schools were shut, the China Open IBM-based forecast recommended "light exercise".
但目前微软和IBM的空气质量预报应用仍存在一定缺陷。由于一处缺陷,微软最新iOS版空气质量检测应用缺乏预测功能。在最近的雾霾“红色预警”期间,北京的学校暂停教学,但中国网球公开赛和IBM共同推出的空气质量预报大数据却推荐民众“轻度运动”。
