Thank you for your question! The formula you've provided for Land Surface Temperature (LST) is commonly used in remote sensing and thermal imagery analysis. However, it's important to note that this specific formulation does not correspond to a single authoritative reference, but rather, it's a simplified version of the Planck's law-based LST calculation. To understand this formula, let's break it down:
LST: Land Surface Temperature (the parameter you want to estimate).
BT: Brightness Temperature (measured from thermal infrared remote sensing data).
w: Wavelength of the emitted radiance.
p: Planck's constant.
e: Emissivity (surface emissivity).
The formula you've provided is a simplified version of the Planck's law-based calculation, which estimates LST from measured Brightness Temperature. It incorporates factors such as the wavelength of emitted radiance, Planck's constant, and emissivity to correct for the effects of surface emissivity and radiance properties.
For a more detailed and authoritative reference, I recommend consulting academic literature and textbooks on remote sensing and thermal infrared imagery analysis. Key references for understanding LST calculations may include:
"Remote Sensing and Image Interpretation" by John A. Richards and Xiuping Jia.
"Remote Sensing for Geoscientists: Image Analysis and Integration" by Paul A. Rosen.
Research papers published in reputable remote sensing and geospatial science journals, which provide in-depth discussions of LST retrieval methodologies.
It's important to be aware that LST calculations can vary depending on the specific context, data sources, and algorithms used, so it's advisable to refer to authoritative sources for the most accurate and context-specific information related to your LST analysis.
