Comparison of Recalibrated Atmospheric Emitted Radiance Interferometer Observations with Line-by-Line Radiative Transfer Model Calculations
The comparison of recalibrated spectra from the atmospheric emitted radiance interferometer prototype (AERI-00) and lineby-line radiative transfer model (LBLRTM) calculations show much smaller differences in the 800-1200 cm atmospheric -1 window region under “clear conditions” compared with the preliminary calibrated data. Results indicate that the new AERI-00 data is in good agreement with sim...
متن کاملAtmospheric Emitted Radiance Interferometer Part II: Water Vapor and Atmospheric Aerosols
Atmospheric Emitted Radiance Interferometer (AERI) spectra provide detailed characterization of the infrared component of the surface radiation budget (Ellingson et al. 1995), support spectroscopic (Clough et al. 1989; Revercomb et al. 1995) and cloud (Smith et al. 1992; Collard et al. 1995) radiative modeling studies for improving radiative transfer calculations, and are the basis for high tim...
متن کاملComparisons of Surface Longwave Radiance Between Line-by-Line Radiative Transfer Model and Atmospheric Emitted Radiance Interferometer Observations from the Atmospheric Radiation Measurement Program
Observed surface downward longwave radiances from the Atmospheric Emitted Radiance Interferometer (AERI) were compared with line-by-line radiative transfer model (LBLRTM) calculations from April 1994 to November 1996 for “clear-sky conditions” in the 800-1250 atmospheric The observed radiance data used herein were measured by the window region. Results show that the mean AERI-LBLRTM AERI at the...
متن کاملInformation Content and Uncertainties in Thermodynamic Profiles and Liquid Cloud Properties Retrieved from the Ground-Based Atmospheric Emitted Radiance Interferometer (AERI)
The Atmospheric Emitted Radiance Interferometer (AERI) observes spectrally resolved downwelling radiance emitted by the atmosphere in the infrared portion of the electromagnetic spectrum. Profiles of temperature and water vapor, and cloud liquid water path and effective radius for a single liquid cloud layer, are retrieved using an optimal estimation–based physical retrieval algorithm from AERI...
متن کاملFeature Dimension Reduction of Multisensor Data Fusion using Principal Component Fuzzy Analysis
These days, the most important areas of research in many different applications, with different tools, are focused on how to get awareness. One of the serious applications is the awareness of the behavior and activities of patients. The importance is due to the need of ubiquitous medical care for individuals. That the doctor knows the patient's physical condition, sometimes is very important. O...
