Research Guide

What is Remote Sensing of Land Surface Temperature?

Remote Sensing of Land Surface Temperature (LST) uses satellite thermal infrared data from Landsat and MODIS to retrieve and analyze urban surface temperatures for heat island intensity mapping.

Researchers apply retrieval algorithms like those in Landsat 8 data processing and indices such as NDVI with LST to quantify urban heat islands. MODIS datasets from 2003-2012 reveal exponential decay of UHI effects toward rural areas (Zhou et al., 2015). Over 10 key papers since 2003, including foundational works with 2400+ citations, document methods and trends.

Key Challenges

Why It Matters

LST mapping from satellites enables monitoring of urban heat dynamics across large scales, informing city planning and climate adaptation. Weng et al. (2003) established LST-vegetation relationships for UHI studies, cited 2415 times, guiding green infrastructure placement. Zhou et al. (2018) reviewed satellite progress, highlighting applications in mega-cities like those in Tran et al. (2005), which assessed Asian UHI with MODIS data.

Key Research Challenges

Atmospheric Correction Variability

Satellite LST retrieval requires precise atmospheric correction, affected by varying water vapor and aerosols in urban environments. Zhou et al. (2018) identify this as a core challenge in SUHI measurement. Validation against ground data remains inconsistent across scales.

Scale Dependency in UHI

UHI intensity varies with spatial resolution, complicating comparisons between Landsat (30m) and MODIS (1km) data. Ziter et al. (2019) show scale-dependent tree canopy cooling effects on daytime heat. Integrating multi-scale data poses methodological hurdles.

Validation Against In-Situ Data

Ground-based LST measurements often mismatch satellite pixels due to urban heterogeneity. Avdan and Jovanovska (2016) developed Landsat 8 algorithms needing robust validation. Discrepancies limit accuracy in dynamic urban settings.
