Simulating satellite urban land surface temperatures: sensitivity to sensor view angle and assumed landscape complexity

William Morrison et al.

Summary: Urban land surface temperature (LST) varies with sensor view angle in satellite earth observation (EO). Neglecting these variations leads to inconsistent urban LST products, which limits their applications in urban weather and climate model evaluations. Therefore, it is important to evaluate the impact of simplifying the urban form and temperature on the modelled LST anisotropy and develop parameterisations to account for LST angular effects.

A thermal radiation directionality correction method for the surface upward longwave radiation of geostationary satellite based on a time-evolving kernel-driven model

Boxiong Qin et al.

Summary: Thermal radiation directionality (TRD) is the anisotropic signature of most surface targets in the thermal infrared domain, which causes uncertainties in estimating surface upward longwave radiation (SULR) from space observations. To overcome this, we proposed a six-parameter time-evolving kernel-driven model (KDM) to correct the TRD effect for single-angle estimated SULR dataset of geostationary satellites.

An atmospheric influence correction method for longwave radiation-based in-situ land surface temperature

Jin Ma et al.

Summary: Obtaining in-situ land surface temperature (LST) using radiation-based methods is widely used for validating satellite LST. This study investigates the atmospheric influence on radiation-based in-situ LST and proposes a correction method combining the Radiative Transfer Equation and Multi-Layer Meteorological Parameters (RTE-MLMP). The results show that the influence follows diurnal and seasonal patterns, and the correction method significantly enhances the accuracy of radiation-based in-situ measured LST.

Impact of 3-D structures on directional effective emissivity in urban areas based on DART model

Qi Zhang et al.

Summary: Thermal infrared (TIR) remote sensing is effective for monitoring urban land surface temperature (LST). The accuracy of LST inversion depends on the emissivity, which is complex in urban areas. This study uses a 3-D radiative transfer model to analyze the impact of 3-D structures on effective emissivity and proposes simple relations between emissivity and 3-D structure parameters. The results show that emissivity directionality and nadir emissivity increment caused by 3-D structures can be larger than other emissivity sources.

Satellite-based daytime urban thermal anisotropy: A comparison of 25 global cities

Dandan Wang et al.

Summary: Remotely sensed land surface temperature (LST) is widely used in urban climate research, but it is subject to considerable angular variation due to non-isothermal facades and sensor viewing angles. This study modified and validated a satellite-based approach to estimate thermal anisotropy and compared the seasonal and diurnal variations in 25 global cities. The results show that urban thermal anisotropy is influenced by sensor angles, solar angles, urban surface properties, and geographic location. The findings provide insights for addressing anisotropy in satellite products and understanding its impact on LST applications in cities.

Modeling the angular effect of MODIS LST in urban areas: A case study of Toulouse, France

Dandan Wang et al.

Summary: Satellite observation of land surface temperature in urban areas is influenced by the three-dimensional structure, making it challenging to accurately characterize urban thermal anisotropy. This study compares airborne observations and MODIS LST signals to investigate seasonal and diurnal patterns of thermal anisotropy, providing insights into modeling methods for assessing urban thermal environments in the future.

Assessment of different kernel-driven models for daytime urban thermal radiation directionality simulation

Lu Jiang et al.

Summary: This study systematically evaluated three single-kernel and eight dual-kernel parametric models for adjusting satellite-derived urban land surface temperatures. The dual-kernel models generally performed better, with those containing the hotspot kernel KHotspot_rou showing higher accuracy. The multi-kernel models sometimes had better accuracies but limited performance improvements compared to single- and dual-kernel models.
