Analyzing Temporal Trends of Urban Evaporation Using Generalized Additive Models

This study aimed to gain new insights into urban hydrological balance (in particular, the evaporation from paved surfaces). Hourly data were obtained simultaneously two high-resolution weighable lysimeters. These lysimeters are covered in pavement sealing types commonly used for sidewalks Berlin, namely cobble-stones and concrete slabs. A paired experiment field conditions is designed determine mechanism by which these of soil affect rate under same climatic conditions. generalized additive model (GAM) applied explain how interact with evaluate variation according type. Moreover, taking advantage fact that experimental design paired, fits a GAM where response variable difference between its explanatory variables As result, conditions, more prone increasing than slabs when precipitation accumulated over 10 h, solar radiation, wind speed increases. On other hand, inclined increase cobblestones relative humidity represents robust modeling approach comparing different order understand they alter balance.
