RISValidation of Point Spread Functions of CERES Radiometers by the Use of Lunar Observations
Publisher: American Meteorological Society
Abstract: The Clouds and the Earth?s Radiant Energy System (CERES) scanning radiometers have been operating to make raster scans of the moon on a quarterly basis to validate the point response function for the three channels of ...
Uncertainty Analysis and Experimental Design in the Monte Carlo Ray-Trace Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite the dominant role of the Monte Carlo ray-trace (MCRT) method in modern radiation heat transfer analysis, the contemporary literature remains surprisingly reticent on the uncertainty of results obtained using it. ...
Estimation and Use of the Radiation Distribution Factor Median for Predicting Uncertainty in the Monte Carlo Ray-Trace Method
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: In a recent contribution, the authors show that the uncertainty in heat transfer results obtained using the Monte Carlo ray-trace (MCRT) method is related to the median of the radiation distribution factor probability ...
Second-Law Considerations in Monte Carlo Ray-Trace and Discrete Green’s Function Analysis of Coupled Radiation and Conduction Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A generic Monte Carlo ray-trace (MCRT) engine for computing radiation distribution factors (RDFs), working in tandem with an efficient finite volume formulation based on discrete Green’s functions (DGFs), has been used to ...
Validation of Geolocation of Measurements of the Clouds and the Earth’s Radiant Energy System (CERES) Scanning Radiometers aboard Three Spacecraft
Publisher: American Meteorological Society
Abstract: The Clouds and the Earth?s Radiant Energy System (CERES) instrument is a scanning radiometer for measuring Earth-emitted and -reflected solar radiation to understand Earth?s energy balance. One CERES instrument was placed ...
Numerical Filtering of Spurious Transients in a Satellite Scanning Radiometer: Application to CERES
Publisher: American Meteorological Society
Abstract: The Clouds and Earth Radiant Energy System (CERES) scanning radiometer was designed to provide high accuracy measurements of the radiances from the earth. Calibration testing of the instruments showed the presence of an ...
Determination of Unfiltered Radiances from the Clouds and the Earth’s Radiant Energy System Instrument
Publisher: American Meteorological Society
Abstract: A new method for determining unfiltered shortwave (SW), longwave (LW), and window radiances from filtered radiances measured by the Clouds and the Earth?s Radiant Energy System (CERES) satellite instrument is presented. ...
Postlaunch Radiometric Validation of the Clouds and the Earth’s Radiant Energy System (CERES) Proto-Flight Model on the Tropical Rainfall Measuring Mission (TRMM) Spacecraft through 1999
Publisher: American Meteorological Society
Abstract: Each Clouds and the Earth?s Radiant Energy System (CERES) instrument contains three scanning thermistor bolometer radiometric channels. These channels measure broadband radiances in the shortwave (0.3?5.0 ?m), total (0.3?>100 ...
Radiometric Performance of the CERES Earth Radiation Budget Climate Record Sensors on the EOS Aqua and Terra Spacecraft through April 2007
Publisher: American Meteorological Society
Abstract: The Clouds and the Earth?s Radiant Energy System (CERES) flight models 1 through 4 instruments were launched aboard NASA?s Earth Observing System (EOS) Terra and Aqua spacecraft into 705-km sun-synchronous orbits with 10:30 ...
Multi-Instrument Comparison of Top-of-Atmosphere Reflected Solar Radiation
Publisher: American Meteorological Society
Abstract: Observations from the Clouds and the Earth?s Radiant Energy System (CERES), Moderate Resolution Imaging Spectroradiometer (MODIS), Multiangle Imaging Spectroradiometer (MISR), and Sea-Viewing Wide-Field-of-View Sensor ...
