摘要: [1] This study investigates the changes in sunshine hours relation to API (Air Pollution Index) across China. Data were collected from a total of 38 cities over period 1960–2009. Sunshine 84% significantly (p 80, are on average 0.7 h d−1 (8.4%) shorter than for days with ≤ 80 under clear-sky condition 2001–2005. In daily and >80 2000s, hour decline 1960s–2000s is 0.8 (13.4%) 1.0 (15.9%) respectively. Winter seasons high (90) exhibit highest (21.5%). The shows that spatiotemporal China could largely be explained terms API.
