“…20 desert sites of 100 ϫ 100 km 2 , and located in Africa and Arabia (see Fig. 3), were selected for their properties, mainly homogeneity and stability with time [22]. In addition, this temporal stability of such sites can be used to cross calibrate different sensors for which viewing geometries are different [23].…”

Since 18 December 2004, the PARASOL satellite is a member of the so-called A-train atmospheric orbital observatory, flying together with Aqua, Aura, CALIPSO, CLOUDSAT, and OCO satellites. These satellites combine for the first time a full suite of instruments for observing aerosols and clouds, using passive radiometer complementarily with active lidar and radar sounders. The PARASOL payload is extensively derived from the instrument developed for the POLDER programs that performs measurements of bidirectionality and polarization for a very wide field-of-view and for a visible͞near-infrared spectral range. An overview of the results obtained during the commissioning phase and the reevaluation after one year in orbit is presented. In-flight calibration methods are briefly described, and radiometric and geometric performances are both evaluated. All algorithms are based on a panel of methods using mainly natural targets previously developed for POLDER missions and adapted or redeveloped in the PARASOL context. Regarding performances, all mission requirements are met except for band 443 (not recommended for use). After one year in orbit, a perfect geometrical stability was found while a slight decrease of the radiometric sensitivity was observed and corrected through an innovative multitemporal algorithm based on observations of bright and scattered convective clouds. The scientific exploitation of PARASOL has now begun, particularly by coupling these specific observations with other A-train sensor measurements.

“…It is located in central Inner Mongolia of Northern China (Figure 1). The calibration site is selected for the following three reasons [4,5]: First, the area is temporally, spatially and radiationally stable in brightness, spatial homogeneity, altimetric and bidirectional effects, seasonal variation, and long-term stability [1]. Second, many clean lakes are located in the calibration site, which can be used to determine the aerosol optical depth (AOD) accurately using the dark object (DO) method [6].…”

“…In this table, only AOD can be changed, and every input AOD corresponds to a TOA radiance as output. (4) Fit the relationship between AOD and TOA radiance and interpolate the AOD with the radiance extracted in step (2). For example, for the image on 16 April 2013, the relationship between AOD and TOA radiance can be fitted as a quadratic equation, which is plotted in Figure 5.…”

Abstract:The wide field of view (WFV) is an optical imaging sensor on-board the Gao Fen 1 (GF-1). The WFV lacks an on-board calibrator, so on-orbit radiometric calibration is required. Zhong et al. proposed a method for cross-calibrating the charge-coupled device on-board the Chinese Huan Jing 1 (HJ-1/CCD) that can be applied to the GF-1/WFV. However, the accuracy is limited because of the wider radiometric dynamic range and the higher spatial resolution of the GF-1/WFV. Therefore, Landsat-8 Operational Land Imager (OLI) imagery with a radiometric resolution similar to that of the GF-1/WFV and DEM extracted from ZY-3 three-line array panchromatic camera (TLC) with a higher spatial resolution were used. A calibration site with uniform surface material and a natural topographic variation was selected, and a model of this site's bidirectional reflectance distribution function (BRDF) was developed. The model has excellent agreement with the real situation, as shown by the comparison of the simulations to the actual OLI surface reflectance. Then, the model was used to calibrate the WFV. Compared with the TOA reflectance from synchronized Landsat-8/OLI images, all errors calculated with the calibration coefficients retrieved in this paper are less than 5%, much less than the errors

“…The spatially and temporally uniform, high surface reflectance areas, including desert sites in North Africa, Saudi Arabia, China, Libya, Mexico, and Peru, the alkali flats, and the ice-surfaces of Greenland and Antarctica, have been studied comprehensively, in multi-year studies, to detect optimal sites [19][20][21]. The desert sand sites have shown the most stable performance [6,21].…”

Analysis of Properties of Reflectance Reference Targets for Permanent Radiometric Test Sites of High Resolution Airborne Imaging Systems

et al. 2010

Reliable and optimal exploitation of rapidly developing airborne imaging methods requires geometric and radiometric quality assurance of production systems in operational conditions. Permanent test sites are the most promising approach for cost-efficient performance assessment. Optimal construction of permanent radiometric test sites for high resolution airborne imaging systems is an unresolved issue. The objective of this study was to assess the performance of commercially available gravels and painted and unpainted concrete targets for permanent, open-air radiometric test sites under sub-optimal climate conditions in Southern Finland. The reflectance spectrum and reflectance anisotropy and their stability were characterized during the summer of 2009. The management of reflectance anisotropy and stability were shown to be the key issues for better than 5% reflectance accuracy.
