Nitrogen trifluoride (NF3) has the potential to make a growing contribution to the Earth?s radiative budget. In this study, the global mean radiative efficiency of NF3 is calculated as 0.188 W·m-2·ppb-1 by line-by-line method. Global warming potentials o...

Contrails are responsible for a significant proportion of aviation?s climate impact. This paper uses data from the European Centre for Medium-Range Weather Forecasts to identify the altitudes and latitudes where formed contrails will not persist. This re...

Contrail cirrus has been emphasized as the largest individual component of aircraft climate impact, yet respective assessments have been based mainly on conventional radiative forcing calculations. As demonstrated in previous research work, individual im...

Radiation management (RM) has been proposed as a conceivable climate engineering (CE) intervention to mitigate global warming. In this study, we used a coupled climate model (MPI-ESM) with a very idealized setup to investigate the efficacy and risks of C...

Black carbon (BC) is a strong radiative forcer. Because of its multiple effects on climate change, BC has been located as the second important impact factor of climate change only after carbon dioxide. Sources of BC include mainly diesel vehicles and bio...

The assessment of direct radiative forcing due to atmospheric aerosols (ADRF) in the Indo Gangetic Plain (IGP), which is a food basket of south Asia, is important for measuring the effect of atmospheric aerosols on the terrestrial ecosystem and for asses...

The IPCC (2013) gives simplified formulas to compute the radiative forcing (RF) resulting from the increase in anthropogenic greenhouse gases (AGG): carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and halocarbons. These formulas allow to compute...

Examples of measurements and calculations are used for evaluation of the clouds influence on the radiative heat exchange in the whole atmosphere, into the clouds, under and above cloud layers. It is shown that the atmosphere on the whole is heated by ...

The climate response of the Northern Hemisphere to the anthropogenic greenhouse gas forcing is studied with a zonally-averaged climate model. First, a simple method is proposed to improve the radiative forcing in climate models with a low vertical res...

Aviation is seeking for ways to reduce its climate impact caused by CO2 emissions and non-CO2 effects. Operational measures which change overall flight altitude have the potential to reduce climate impact of individual effects, comprising CO2 but in part...

Earth’s global surface temperature shows variability on an extended range of temporal scales and satisfies an emergent scaling symmetry. Recent studies indicate that scale invariance is not only a feature of the observed temperature fluctuations, b...

Satellite data suggest that summertime aerosol optical depth (AOD) over the southeastern USA depends on the air/land surface temperature, but the magnitude of the radiative effects caused by this dependence remains unclear. To quantify these radiative ef...
