METEOROLOGY – CLOUD & VIIBILITY CALCULATOR
Cloud Top Temperature
A precise tool.
What is the Cloud Top Temperature & How does it work?
Cloud top temperature is a critical parameter in meteorology, providing insights into the altitude and composition of clouds. It can be derived from satellite imagery by analyzing the brightness temperatures observed at various wavelengths.
The relationship between cloud top temperature and atmospheric pressure helps in understanding cloud dynamics and their potential for precipitation. Lower cloud tops generally indicate warmer air, while higher cloud tops suggest colder temperatures.

T_{text{cloud}} = frac{L_0}{lambda^4} – frac{F_s}{sigma}
T_{text{cloud}} = Cloud top temperature (K)
L_0 = Radiance at the surface (W m-2 sr-1 µm-1)
lambda = Wavelength of observation (µm)
F_s = Solar flux (W m-2)
sigma = Stefan-Boltzmann constant (W m-2 K-4)
