Estimation of global temperature and Bond albedo anomalies in response to radiative imbalances

Autor: António Heitor Reis

Publikováno v: International Journal of Global Warming. 23:111

Here, the author presents an analysis of the evolution of global temperature and Bond albedo anomalies in the period 2001-2013. Based on the radiative balance at the top of the atmosphere, an equation is presented to estimate the temperature anomaly
