To find the effective (blackbody) temperature of a planet, it can be calculated by equating the power received by the planet to the known power emitted by a blackbody of temperature T. Take the case of a planet at a distance D from the star, of luminosity L. Assuming the star radiates isotropically and that the planet is a long way from the star, the power absorbed by the planet is given by treating the planet as a disc of radius r, which intercepts som… WebLandsat Collection 2 surface temperature has a scale factor of 0.00341802 and an additional offset of 149.0 per pixel. For example, a pixel value of 44,947 is multiplied by 0.00341802 for the scale factor and 149.0 is added for the additional offset to get 302.6 Kelvin after the scale factor is applied.
