WebIn each model, the total aerosol radiative effect is estimated as aerosol effective radiative forcing (ERF) (Materials and Methods). We demonstrate the relationship between aerosol ERF and regional OHU trend during the 21st century among 15 of the 26 CMIP5 models according to the availability of model aerosol ERF (table S1) ( 6 ). WebThe effective radiative forcing (ERF) from 13 different forcing agents (Table 3) is determined from the concentrations of each greenhouse gas, plus emissions of short-lived climate forcers and natural forcing, and is output from the model as a (years × 13) array. From the ERF, temperature change is calculated. how many decimal places in euros https://daniutou.com
