主 题:near-infrared spectrometer low-temperature Arctic sea ice
摘 要:The extremely low temperature,high humidity and limited power supply pose considerable challenges when using spectrometers within the Arctic sea *** feasibility of using a miniature low-power near-infrared spectrometer module to measure solar radiation in Arctic sea ice environments was investigated in this *** and integration time dependences of the spectrometer module were examined over the entire target operating range of–50°C to 30°C,well below the specified operating range of this *** these observations,a dark output prediction model was developed to represent dark output as a function of temperature and integration ***-induced biases in the saturation output and linear operating range of the spectrometer were also *** and integration time dependences of the signal output were *** signal output correction models were developed and compared,to convert the signal output at any temperature within the operating temperature range and integration time to that measured at the reference temperature and integration *** overall performance of the spectrometer was evaluated by integrating it into a refined fiber optic spectrometry system and measuring solar irradiance distribution in the ice cover with thickness of 1.85 m in the Arctic during the 9th Chinese National Arctic Research *** general shape of the measured solar irradiance above the snow surface agreed well with that measured by other commercial oceanographic *** measured optical properties of the sea ice were generally comparable to those of similar ice measured using other *** approach provides a general framework for assessing the feasibility of using spectrometers for applications in cold environments.
