Abstract The collective representation within global models of aerosol, cloud, precipitation, and their radiative properties remains unsatisfactory. They constitute the largest source uncertainty in predictions climatic change hamper ability numerical weather prediction to forecast high-impact events. joint European Space Agency (ESA)–Japan Aerospace Exploration (JAXA) Earth Clouds, Aerosol Radiation Explorer (EarthCARE) satellite mission, scheduled for launch 2018, will help resolve these...
This paper reports on a new satellite sensor, the Geostationary Earth Radiation Budget (GERB) experiment. GERB is designed to make first measurements of Earth's radiation budget from geostationary orbit. Measurements at high absolute accuracy reflected sunlight Earth, and thermal emitted by are made every 15 min, with spatial resolution subsatellite point 44.6 km (north–south) 39.3 (east–west). With knowledge incoming solar constant, this gives primary forcing response components...
Measurements of the top‐of‐the‐atmosphere outgoing longwave radiation (OLR) for July 2003 from Meteosat‐7 are used to assess performance numerical weather prediction version Met Office Unified Model. A significant difference is found over desert regions northern Africa where model emits too much OLR by up 35 Wm −2 in monthly mean. By cloud‐screening data we find an error 50 associated with cloud‐free areas, which suggests surface temperature, emissivity, or atmospheric transmission. building...

The Earth Radiation Budget at the top of atmosphere quantifies how gains energy from Sun and loses to space. It is fundamental importance for climate change. In this paper, current state-of-the-art satellite measurements reviewed. Combining all available measurements, most likely value Total Solar Irradiance a solar minimum 1362 W/m 2, albedo 29.8%, annual mean Outgoing Longwave 238 2.

Monitoring the Earth Energy Imbalance (EEI) is of prime importance for a predictive understanding climate change. Furthermore, monitoring EEI gives an early indication on how well mankind doing in implementing Paris Climate Agreement. defined as small difference between incoming energy receives from Sun and outgoing lost by to space. The cumulated system, particularly oceans, due their substantial heat capacity, results global temperature rise. Currently best estimates absolute value EEI,...
The increasing impact of aviation on global climate change underscores the critical need for accurate quantification its environmental effects. Among them, persistent contrails and aviation-induced cloudiness are recognized as most significant contributors, yet their effects remains uncertain [1]. During last decades, physics-based models, which involve simulation contrail formation, evolution, radiative forcing by integrating aircraft specifications meteorological data, have been primary...

An advanced operational algorithm has been developed for the routine calibration of Meteosat radiometer solar channel. The method relies on calculated radiances over bright desert sites whereas ocean targets are used consistency checks. Calibration errors estimated accounting uncertainties both sensor spectral response characterization and target property description. This to systematically calibrate Meteosat-5 -7 observations. Results show that it is possible visible band with an accuracy...
Abstract Clouds interact with atmospheric radiation and substantially modify the Earth's energy budget. Cloud formation processes occur over a vast range of spatial temporal scales, which make their thorough numerical representation challenging. Therefore, impact parameter choices for simulations cloud‐radiative effects is assessed in current study. Numerical experiments are carried out using ICOsahedral Nonhydrostatic (ICON) model varying grid spacings between 2.5 80 km different...
