Analysis of Rotating Shadowband Spectroradiometer (RSS) Data
(a) The RSS optical resolution is nonlinear over the spectrum: for a 512-pixel instrument d/dpixel = 0.3 nm at 350 nm, 1 nm at 500 nm, broadening to ≈ 4 nm at 1 μm. We have an improved version in test at Atmospheric Sciences Research Center (ASRC) that doubles the number of pixels to 1024, with commensurate improvement in resolution. technique used by the MFRSR, and so it too provides spectrall...
متن کاملColumnar water vapor retrievals from multifilter rotating shadowband radiometer data
[1] The multifilter rotating shadowband radiometer (MFRSR) measures direct and diffuse irradiances in the visible and near-infrared spectral range. In addition to characteristics of atmospheric aerosols, MFRSR data also allow retrieval of precipitable water vapor (PWV) column amounts, which are determined from the direct normal irradiances in the 940-nm spectral channel. The HITRAN 2004 spectra...
متن کاملRetrievals of cloud optical depth and effective radius from Thin-Cloud Rotating Shadowband Radiometer measurements
[1] A Thin-Cloud Rotating Shadowband Radiometer (TCRSR) was developed and deployed in a field test at the Atmospheric Radiation Measurement Climate Research Facility’s Southern Great Plains site. The TCRSR measures the forward-scattering lobe of the direct solar beam (i.e., the solar aureole) through an optically thin cloud (optical depth < 8). We applied the retrieval algorithm of Min and Duan...
متن کاملRemoving Systematic Errors from Rotating Shadowband Pyranometer Data
Rotating Shadowband Pyranometers (RSPs) have been deployed to measure global, beam, and diffuse irradiance because they do not require manual adjustment of trackers. However, a RSP requires the use of solar cell based pyranometers which underestimate diffuse irradiance by 20-30% under clear sky conditions. Algorithms were derived to address many of the systematic errors in solar cell based meas...
متن کاملRetrieval of Aerosol Optical Depth, Aerosol Size Distribution Parameters, Ozone and Nitrogen Dioxide Column Amounts from Multifilter Rotating Shadowband Radiometer Data
The MultiFilter Rotating Shadowband Radiometer (MFRSR) (Harrison and Michalsky 1994a, 1994b) measures atmospheric column extinction of the direct solar beam and the diffuse radiation intensity at six wavelengths. Located at the National Aeronautics and Space Administration's Goddard Institute for Space Studies in New York City, the instrument has six spectral channels at 415, 501, 616, 672, 870...
