根据类型和大小的气溶胶散射,(米氏和瑞利散射),大气窗口过滤辐射和吸收、传输和变换的波长的能量影响被困或反射回来。气溶胶的封锁导致显著减少和大幅改善空气质量在某些地区(即不是无处不在)。评估正在进行中,但是我认为我们必须等到一个赛季过去了,活动了。一个巨大影响温度afaik没有观察到,如果,是向当地的温度下降,而不是增加。总之,降低经济活动的积极作用停止,因为没有或很少正尝试使用重置为过渡到更多的可持续性。我发现两个例子,到目前为止:东南亚从卫星观测https://www.sciencedirect.com/science/article/pii/S0048969720331788 >…执行锁定在不同程度控制疾病的传播,这对自然环境带来了一些积极的影响。摩洛哥,略有减少(-0.3°C)在室内,但更高的瑞士https://www.sciencedirect.com/science/article/pii/S0048969720330588…没有多少天温度超过40°C。>…… the emissions from vehicle exhaust and industrial production were significantly reduced, which contribute to the decrease in the concentrations of the studied pollutants ... local emission reductions related to the lockdown were overwhelmed by the contribution of long-range transported aerosols outside areas. tl, dr: No, probably not, it may locally temporarily lower the temperature by a tiny bit, but overall this effect seems to be shadowed. But future work will show, it is too early to be definitive because the story still develops.
