Disclosed is a portable thermal infrared load field calibration and water surface temperature verification system device. A floating device is composed of a polyethylene-aluminum composite pipeline, a hard plastic tube, a basketball and a right-angle tee connector. A measuring instrument carrying platform is arranged on the top of the floating device, and an infrared radiometer KT15, a data acquisition unit and a storage battery are arranged on the platform in a carrying mode. The bottom of the carrying platform and the KT15 are wrapped by silver paper, so that the influence of infrared radiation of a measuring table itself on the observed result is reduced. By the adoption of the device, automatic observation can be achieved outdoors, long-term observation data can be stored, and the device can be placed on the water surface for measuring; the collected radiation temperature data and synchronous sounding data are simultaneously input to a radiometric calibration module which is developed in a matched mode, and the calibration coefficient can be calculated to be used for radiometric calibration of a thermal infrared sensor; meanwhile, in times of water surface measurement, due to the fact that the radiation temperature measured by the KT15 represents the water body radiation value of certain area, the water surface temperature on behalf of a certain area range can be calculated by the way of combining a matched temperature verification module, and the temperature verification module is used for verifying the remote sensing retrieval surface temperature.
Description
technical field [0001] The invention relates to a set of portable thermal infrared load field calibration and water surface temperature verification system, which can realize long-term serial ground radiation temperature data acquisition, and can be used in the fields of thermal infrared remote sensing data radiation calibration and remote sensing surface temperature inversion algorithm verification. effect. Background technique [0002] The radiation temperature of the water surface is to express the radiation energy of the surface of the water body with the blackbody temperature of the same radiation amount. The radiation temperature of the water surface is an energy concept, which is not equal to the water surface temperature mentioned in ordinary times, because the specific emissivity of the water body is close to 1 but not equal to 1. , and the water surface radiation temperature also contains some external information (such as the reflected radiation of the water body ...
