Abstract The ocean color component of the Aerosol Robotic Network (AERONET-OC) has been implemented to support long-term satellite investigations through cross-site consistent and accurate measurements collected by autonomous radiometer systems deployed on offshore fixed platforms. AERONET-OC data products are normalized water-leaving radiances determined at various center wavelengths in visible near-infrared spectral regions. These complement atmospheric AERONET aerosol products, such as...
Abstract. The CERES Ocean Validation Experiment (COVE) was an instrument suite located at the Chesapeake Light Station approximately 25 kilometers east of Virginia Beach, (36.9° N, 75.7° W). COVE provided surface verification for Clouds and Earth’s Radiant Energy System (CERES) satellite measurements 16 years. However, large light station occupied 15 % field view upwelling longwave flux measurement (LW↑), so radiation from structure artificially perturbed measurements. Hence, we use data...
Abstract. This study presents the results of Fourth Filter Radiometer Comparison that was held in Davos, Switzerland, between 28 September and 16 October 2015. Thirty filter radiometers spectroradiometers from 12 countries participated including reference instruments global aerosol networks. The absolute differences all compared to have been based on World Meteorological Organization (WMO) criterion defined as follows: 95% measured data has be within 0.005 ± 0.001∕m (where m is air mass). At...
When radiometers on satellites point toward Earth with the goal of sensing an important variable quantitatively, rather than just creating a pleasing image, task at hand is often not simple. The electromagnetic energy detected by puzzle various signals; it must be solved to quantify specific physical variable. This task, called retrieval or remote-sensing process, most satellite-based observation programs. It would ideal test algorithms for processes in sealed laboratory, where all relevant...
Abstract. This study presents the results of 4th Filter Radiometer Comparison that was held in Davos, Switzerland, between September 28 and October 16, 2015. Thirty filter radiometers spectroradiometers from 12 countries participated including reference instruments global aerosol networks. The absolute differences all compared to have been based on WMO criterion defined as 95 % measured data has be within 0.005 ± 0.001/m (where m is air mass). At least 24 out 29 achieved this goal at both...
In order to verify the COVE (CERES Ocean Validation Experiment) platform measurements and characterize ocean optical properties, airborne of spectral broadband shortwave upwelling downwelling radiative fluxes were made onboard NASA Langley OV-10 aircraft between July, 2001 March, 2003. The processed data derived albedos are compared with other observed model simulation results, comparisons show consistently good agreement.
