Warm and moist air intrusions into the winter Arctic: a Lagrangian view on the near-surface energy budgets [PDF]

Atmospheric Chemistry and Physics, 2022
In this study, warm and moist air intrusions (WaMAIs) over the Arctic Ocean sectors of Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, Chukchi Sea, and Beaufort Sea in 40 recent winters (from 1979 to 2018) are identified from the ERA5 reanalysis ...

Modelling surface temperature and radiation budget of snow-covered complex terrain [PDF]

The Cryosphere, 2022
The surface temperature controls the temporal evolution of the snowpack, playing a key role in metamorphism and snowmelt. It shows large spatial variations in mountainous areas because the surface energy budget is affected by the topography, for instance

Long-Time Variation and Mechanism of Surface Energy Budget Over Diverse Geographical Regions in Pakistan

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Earth's energy budget is a major force that drives global climate. The long-term pattern of land surface energy budget with pronounced biophysical effects on climate was normally ignored at a regional scale, particularly in Pakistan.

The Summer Surface Energy Budget of the Ice-Free Area of Northern James Ross Island and Its Impact on the Ground Thermal Regime

Atmosphere, 2020
Despite the key role of the surface energy budget in the global climate system, such investigations are rare in Antarctica. In this study, the surface energy budget measurements from the largest ice-free area on northern James Ross Island, in Antarctica,

Characterizing energy budget variability at a Sahelian site: a test of NWP model behaviour [PDF]

Atmospheric Chemistry and Physics, 2017
We use observations of surface and top-of-the-atmosphere (TOA) broadband radiation fluxes determined from the Atmospheric Radiation Measurement programme mobile facility, the Geostationary Earth Radiation Budget (GERB) and Spinning Enhanced Visible ...

Clouds damp the radiative impacts of polar sea ice loss [PDF]

The Cryosphere, 2020
Clouds play an important role in the climate system: (1) cooling Earth by reflecting incoming sunlight to space and (2) warming Earth by reducing thermal energy loss to space. Cloud radiative effects are especially important in polar regions and have the

Parameterisation of sea and lake ice in numerical weather prediction models of the German Weather Service [PDF]

Tellus: Series A, Dynamic Meteorology and Oceanography, 2012
A bulk thermodynamic (no rheology) sea-ice parameterisation scheme for use in numerical weather prediction (NWP) is presented. The scheme is based on a self-similar parametric representation (assumed shape) of the evolving temperature profile within the ...

Quantifying the thermodynamic entropy budget of the land surface: is this useful? [PDF]

Earth System Dynamics, 2011
As a system is moved away from a state of thermodynamic equilibrium, spatial and temporal heterogeneity is induced. A possible methodology to assess these impacts is to examine the thermodynamic entropy budget and assess the role of entropy production ...

Deriving surface ultraviolet radiation from CERES surface and atmospheric radiation budget: Methodology [PDF]

Journal of Geophysical Research: Atmospheres, 2005
We describe an algorithm that retrieves the surface UVB (280–315 nm) and UVA (315–400 nm) irradiances from the Surface and Atmosphere Radiation Budget (SARB) product of Clouds and the Earth's Radiant Energy System (CERES). The SARB product we use here routinely calculates the vertical profiles of shortwave, longwave, and window channel irradiances with

The Surface Radiation Budget over Oceans and Continents

Journal of Climate, 1998
Abstract An updated evaluation of the surface radiation budget in climate models (1994–96 versions; seven datasets available, with and without aerosols) and in two new satellite-based global datasets (with aerosols) is presented. All nine datasets capture the broad mean monthly zonal variations in the flux components and in the net ...
