Solar radiation makes great influence on human perception of thermal balance and comfort. This study investigated the effect glazing system design factors comfort in presence solar aims to clarify relationship between performance through simulations. Specifically, a cellular office unit with different window sizes, types, shading devices was set for simulating environment based an integrated MR...

Present-day Arctic and Antarctic radiation budgets of the National Center for Atmospheric Research Community Climate Model version 3 (CCM3) are presented. The CCM3 simulation is from a prescribed and interannually varying sea surface temperature integration from January 1979 through August 1993. Earth Radiation Budget Experiment (ERBE) data from 1985 through 1989 are used for validation of top-...

Abstract We monitored lake surface water temperatures from 1992 to 2019 in Lake Kasumigaura, a shallow Japan. hypothesized that increases of shortwave radiation had increased and heat fluxes more than the air temperature. used flux analyses sensitivity test hypothesis. The solar gradually during study period manner consistent with phenomenon global brightening. increase was especially apparent ...

Solar diffuse radiation data including global radiation, shortwave and longwave balances, net radiation and sunshine hours have been extensively analyzed to study the variation of diffuse radiation with turbidity and cloud discharges appearing in the form of atmospherics over the tropics. Results of surface radiation measurements at Calcutta, Poona, Delhi and Madras are presented together with ...

The concept of canopy spectral invariants expresses the observation that simple algebraic combinations of leaf and canopy spectral transmittance and reflectance become wavelength independent and determine a small set of canopy structure specific variables. This set includes the canopy interceptance, the recollision and the escape probabilities. These variables specify an accurate relationship b...

Land surface albedo, a key parameter to derive Earth’s surface energy balance, is used in the parameterization of numerical weather prediction, climate monitoring and climate change impact assessments. Changes in albedo due to fire have not been fully investigated on a continental and global scale. The main goal of this study, therefore, is to quantify the changes in instantaneous shortwave alb...

Close examination of direct normal solar irradiance (DNSI) and downwelling diffuse irradiance (DDI) on cloud-free days at the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site reveals anticorrelated shortterm (several minute) fluctuations, especially prominent in the hours around local solar noon; i.e., DDI increases as DNSI decreases. These fluctuations are correlated or...

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,...
