Cirrus cloud radiative forcing
WebCirrus cloud daytime top-of-the-atmosphere radiative forcing (TOA CRF) is estimated for a 2-yr NASA Micro-Pulse Lidar Network (532 nm; MPLNET) dataset collecte ... We hypothesize that subarctic interannual cloud variability is likely a considerable influence on global cirrus cloud forcing sensitivity, given the irregularity of polar versus ... WebContrails and Cirrus Clouds from Aviation. Clouds can have either a cooling or a warming effect: They can cause warming by trapping long-wave (infrared) radiation from the Earth, and. They can cause cooling by reflecting short-wave (visible and ultraviolet) solar radiation back into space. Overall, however, clouds caused by air travel emissions ...

It should be noted that there is a fifth WebFeb 10, 2024 · Abstract. Cirrus cloud radiative effects are largely affected by ice microphysical properties, including ice water content (IWC), ice crystal number concentration (Ni) and mean diameter (Di). These characteristics vary significantly due to thermodynamic, dynamical and aerosol conditions. In this work, a global-scale observation dataset is …
WebSep 1, 1994 · If the observed solar cloud forcing in excess of 100 W-m −2 is to be attributed to cirrus anvils alone, then the optical depth of these anvils must be at least 5 (assuming 50% cloud cover and an ice crystal effective radius of 15 µm). The net radiative forcing of cirrus near the tropical tropopause is positive (heating) for cloud optical ...
