Seasonal averaged impacts of aerosols and clouds on POAI over the SC from 2003 to 2019: (a–d) PAE; (e–h) PCE; (i–l) PCE minus PAE (Unit: %). (a,e,i) spring (March–April–May); (b,f,j) summer (June–July–August); (c,g,k) autumn (September–October–November); (d,h,l) winter (December–January–February). The numbers outside the parentheses represent the regional averaged PAE or PCE, while the numbers inside the parentheses represent the regional averages of AE or CE in the unit of kWh/m2/d. The map was generated by ESRI ArcGIS 10.5 software available at the ESRI website (https://www.esri.com/en-us/arcgis/products/arcgis-platform/overview). The administrative boundary shapefile for southern China is available at the RESDC website (https://www.resdc.cn/).
