“…Absolute calibration and thus spectral responses of the filters did not vary when measurements were made in a vacuum chamber. Preflight calibration was also successfully compared to OCTS calibration through a round robin of both projects' calibrating radiometers [29]. However, it was foreseen that because of the ultraviolet irradiation of the external lenses, a slight decrease in the sensitivity of POLDER blue spectral bands could occur (10% maximum for 443 nm band after three years, but less than 1% for 670).…”

Abstract-POLDER is a CNES instrument on board NASDA's ADEOS polar orbiting satellite, which was successfully launched in August 1996. On October 30, 1996, POLDER entered its nominal acquisition phase and worked perfectly until ADEOS's early end of service on June 30, 1997. POLDER is a multispectral imaging radiometer/polarimeter designed to collect global and repetitive observations of the solar radiation reflected by the earth/atmosphere system, with a wide field of view (2400 km) and a moderate geometric resolution (6 km). The instrument concept is based on telecentric optics, on a rotating wheel carrying 15 spectral filters and polarizers, and on a bidimensional charge coupled device (CCD) detector array. In addition to the classical measurement and mapping characteristics of a narrow-band imaging radiometer, POLDER has a unique ability to measure polarized reflectances using three polarizers (for three of its eight spectral bands, 443 to 910 nm) and to observe target reflectances from 13 different viewing directions during a single satellite pass.One of POLDER's original features is that its in-flight radiometric calibration does not rely on any on-board device. Many calibration methods using well-characterized calibration targets have been developed to achieve a very high calibration accuracy. This paper presents the various methods implemented in the in-flight calibration plan and the results obtained during the instrument calibration phase: absolute calibration over molecular scattering, interband calibration over sunglint and clouds, multiangular calibration over deserts and clouds, intercalibration with Ocean Color and Temperature Scanner (OCTS), and water vapor channels calibration over sunglint using meteorological analysis. A brief description of the algorithm and of the performances of each method is given.

“…Table III shows the specifications of the three transfer standard radiometers to be used in the GOSAT OCO crosscalibration. The 0.76 m radiometer was manufactured along with other visible and near infrared radiometers for the OCTS-POLDER cross-calibration experiment in 1994 [3]. The interference filter was changed to a Barr hard-coating filter.…”

“…Three transfer standard radiometers were prepared for the cross-calibration. The 0.76 m transfer standard radiometer was developed for the cross-calibration between the OCTS and the POLDER on the ADEOS satellite [3]. The 1.6 m transfer standard radiometer was developed at the National Institute of Advanced Industrial Science and Technology (AIST) and had a good performance including the size of the source effect (SSE) [4].…”
