GLASS Daytime All-Wave Net Radiation Product: Algorithm Development and Preliminary Validation
Mapping surface all-wave net radiation (Rn) is critically needed for various applications. Several existing Rn products from numerical models and satellite observations have coarse spatial resolutions and their accuracies may not meet the requirements of land applications. In this study, we develop the Global LAnd Surface Satellite (GLASS) daytime Rn product at a 5 km spatial resolution. Its al...
متن کاملSeasonal changes in the fraction of global radiation retained as net all-wave radiation and their hydrological implications
High linear correlation between concurrent measurements of net all-wave radiation Q*, and global incoming short-wave radiation Eg-l was found for hourly, daytime and 24-h totals measured over a grassland catchment in the subhumid climate region of southeastern Australia. Five years of daily measurements were used to study the temporal variability in the fraction of incoming short-wave radiation...
متن کاملLocal-Scale Urban Meteorological Parameterization Scheme (LUMPS): Longwave Radiation Parameterization and Seasonality-Related Developments
Recent developments to the Local-scale Urban Meteorological Parameterization Scheme (LUMPS), a simple model able to simulate the urban energy balance, are presented. The major development is the coupling of LUMPS to the Net All-Wave Radiation Parameterization (NARP). Other enhancements include that the model now accounts for the changing availability of water at the surface, seasonal variations...
متن کاملGround Wave Propagation on Mixed-Paths through Urban Areas
Medium-frequency (MF) ground wave propagation is playing one of the most important roles for a long distance communication. When the surface impedance of the earth along the propagation path changes the ground wave propagation is influenced strongly as it occurs when the radio wave traverses a border from an urban area to a suburban area or viceversa [1]-[4]. The measurements of the ground wave...
متن کاملTree approximation of the long wave radiation parameterization in the NCAR CAM global climate model
The computation of Global Climate Models (GCMs) presents significant numerical challenges. This paper presents new algorithms based on sparse occupancy trees for learning and emulating the longwave radiation parameterization in theNCAR CAMclimate model. This emulation occupies by far the most significant portion of the computational time in the implementation of the model. From the mathematical...
