Figure 4: Association of SUHII in India with evapotranspiration (ET).
From: Flip flop of Day-night and Summer-Winter Surface Urban Heat Island Intensity in India

The SUHII for summer days (a) and winter days (b) are overlaid on the seasonal ET. The differences in the ET between urban and nearby non-urban regions are estimated for the summer (c) and winter (d) season. The summer and winter daytime SUHII are negatively associated with differences in ET between urban and nearby non-urban region ((a) and (b) respectively). The overall variability of differences in ET between urban and nearby non-urban regions for summer and winter season are presented in (c) and (d) respectively. The temperature is presented in °C. The figures are generated with Arc Map Ver 10.2 (http://www.esri.com/software/arcgis/arcgis-for-desktop) and, MATLAB R2012b (http://in.mathworks.com/products/new_products/release2012b.html).
