How is LST calculated in Landsat 8?
How to calculate Land Surface Temperature with Landsat 8 satellite images
- TOA (L) = ML * Qcal + AL
- BT = (K2 / (ln (K1 / L) + 1)) − 273.15.
- NDVI = (Band 5 – Band 4) / (Band 5 + Band 4)
- Pv = Square ((NDVI – NDVImin) / (NDVImax – NDVImin))
- ε = 0.004 * Pv + 0.986.
- LST = (BT / (1 + (0.00115 * BT / 1.4388) * Ln(ε)))
What is band ratio?
The band ratio is the numerator divided by the denominator. ENVI checks for division-by-zero errors and sets them to 0. You can also calculate multiple ratios and output them as multiple bands in one file. To calculate band ratios: Display a multispectral image.
What is the temperature of the land?
According to GISS, the global mean surface air temperature for that period was estimated to be 57 F (14 C). That would put the planet’s average surface temperature in 2017 at 58.62 F (14.9 C).
How to calculate LST from Landsat 8 images?

What are the sensor IDs of Landsat 7 and 8?
Set the property manually to avoid that. The sensor IDs of Landsat 5, 7 and 8 are ‘TM’, ‘ETM+’ and ‘OLI_TIRS’, respectively. For creating simple cloud-free Landsat composites, Earth Engine provides the ee.Algorithms.Landsat.simpleComposite () method.
