To improve the forecasting accuracy of a radiation emulator in weather prediction model over Korean peninsula, learning rate used neural network training was automatically optimized using Sherpa. The Sherpa experiment results were compared with two control simulation rates 0.0001 and 1 for different batch sizes (full to 500). In offline evaluation, showed significant improvements predicting lon...

Abstract. The surface mass balance scheme dEBM (diurnal Energy Balance Model) provides a novel interface between the atmosphere and land ice for Earth system modeling, which is based on energy of glaciated surfaces. In contrast to empirical schemes, accounts changes in Earth’s orbit atmospheric composition. only requires monthly forcing (precipitation, temperature, shortwave longwave radiation,...

We consider time evolution of Turing patterns in an extended system governed by an equation of the Swift-Hohenberg type, where due to an external periodic parameter modulation longwave and shortwave patterns with length scales related as 1:3 emerge in succession. We show theoretically and demonstrate numerically that the spatial phases of the patterns, being observed stroboscopically, are gover...

Methane (CH4) has significant absorption bands at wavelengths of 1.7, 2.3, 3.3 and 7.6 ?m which absorb incoming solar ‘shortwave’ (SW) radiation contribute to radiative forcing (RF). A comprehensive quantification CH4 SW RF is presented using a narrow-band transfer model calculate spatially monthly resolved estimates its impact on longwave (LW) stratospheric temperature adjusted (SARF). These n...

As part of a larger study of carbon dioxide and energy exchange, energy components in an open-canopied juniper–sagebrush ecosystem located in the semi-arid region of Eastern Oregon were measured with the eddy covariance technique. Daytime net radiation averaged 20–30% greater than the sum of sensible, latent and soil heat fluxes. On cloudless days several days after a rain event the imbalance w...

Abstract. Including radiative transfer processes within the urban canopy layer into microscale climate models (UCMs) is essential to obtain realistic model results. These include interaction of buildings and vegetation with shortwave longwave radiation, thermal emission, radiation reflections. They contribute differently budget surfaces. Each process requires different computational resources p...

Abstract The Western Tibetan Vortex (WTV) is a large-scale circulation pattern identified from year-to-year variability, which was used to understand the causal mechanisms for slowdown of glacier melting over western Plateau (TP). A recent argument has suggested WTV set wind field anomalies resulting variability in near-surface air temperatures TP (above 1500 m), which, turn, likely driven by s...

[1] The Geostationary Earth Radiation Budget Intercomparisons of Longwave and Shortwave (GERBILS) radiation field experiment was conducted in June 2007 over North Africa to study dust aerosols from aircraft, satellite, and ground measurements. We present results from a case study on June 21, 2007 where coincident measurements from a space borne lidar, aircraft profiles, and multiple satellite i...

[1] This paper analyzes and attributes spatial and temporal patterns of changes in the diurnal cycle of land surface air temperature in 20 simulations from 11 global coupled atmosphere-ocean general circulation models during the 20th century and the 21st century under the SRES A1B scenario. Most of the warming in the maximum (Tmax) and minimum (Tmin) temperatures from 1900 to 2099 is attributed...

In this paper, the coupled WRF/SSiB model, accompanied by a Karst Rocky Desertification (KRD) map of the Guizhou Karst Plateau (GKP) of China, was applied to detect how the changed vegetation and soil characteristics over the GKP modify the energy balance at the land surface. The results indicated that land degradation led to reduced net radiation by inducing more upward shortwave and longwave ...
