Description
Technical field
The utility model relates to Ocean Surveying technology, particularly a kind of surface air, water body cortex and upper epidermis temperature synchronous measuring apparatus.
Background technology
Sea surface temperature (Sea Surface Temperature SST) is one of most important physical parameter in ocean, is also one of main marine eco-environment parameter.SST has widespread use and is worth in many fields such as the researchs such as ocean-atmosphere interaction, Global climate change, mesoscale ocean process, water body and the marine eco-environment, marine numerical simulation, offshore thermal pollution evaluations.Thermal Infrared Remote Sensing technology is through the development of many decades, the main means that sea surface temperature is surveyed have been become, what satellite sensor can be measured is the water body skin temperature of (comprising other atural object), be water body cortex (the about 0.5 millimeter of water layer of epidermis) temperature, when satellite sensor is calibrated in-orbit, need first Measurement accuracy skin temperature.Therefore, Measurement accuracy skin temperature is not only extremely important to the calibration of satellite thermal infrared sensor, the surface temperature of satellite remote sensing inverting is carried out to validity check also extremely important.Measure at present the contactless surveying instrument of skin temperature employing, measuring accuracy is not high, and error is greater than 0.5K(Kelvin conventionally) be even greater than 1K.Restrict the satellite thermal infrared sensor precision of calibration precision and satellite remote sensing temperature product in-orbit, and then affected the application of remote sensing temperature product in every profession and trade.
