Surface Radiation and Column Aerosol Optical Depth Trends |
||
|
The SURFRAD network of shortwave and longwave radiation operated by the Surface Radiation Research Branch (SRRB) has collected radiation data since 1995. The solar broadband data follow the WMO/WCRP Baseline Surface Radiation Network protocols and are near state-of-the-art accuracy. Concurrently, spectral direct and diffuse solar radiation data have been collected using the multi-filter rotating shadowband radiometer. These spectral data can be exploited to retrieve aerosol optical depth as a function of wavelength and water vapor column for clear conditions. Moreover, it has been demonstrated that cloud optical depths may be retrieved using these data. Broadband ultraviolet radiation data have been collected with calibrations provided by the SRRB’s Central Ultraviolet Calibration Facility. This data set represents a unique opportunity to perform model validation studies and study trends in radiation and the primary variables that affect those trends. |
