Floatation device and water body apparent spectral in-situ measurement system for water body optical observation

Technical field

The utility model relates to optical observation fields, and in particular to Ocean Color Remote Sensing scene apparent spectral observes field, especially It is related to a kind of water body in-situ apparent spectral observation device.

Background technique

From water spoke brightness (L_w) and Remote Sensing Reflectance (R_rs) be marine optics core parameter, such as inherent optics amount, Ye Lv Other parameters such as plain concentration and optics shallow water substrate, all can be by R_rsInverting obtains.Moreover, the L of field measurement_wIt can be used for airborne Or in the ground calibration of airborne sensor, validity check and atmospheric correction.

Field measurement L_wSpectrum has had more than 50 years history, developed and implemented in the prior art there are three types of measurement Method, including the above mensuration of the water surface, underwater section mensuration and floating on water mensuration, although these methods are in measure field It is easy to implement, but they fail to the L for directly measuring water body_w, and go to derive L by measuring some associated arguments_w, by In there is some uncertain factors, the L for causing these methods to be derived by derivation process_wWith very big error.

As described in many researchs, L is estimated using the above mensuration of the water surface_wWhen, it, can not if sea is roughened by wave It is accurate to determine gas-water interface reflectivity, then being difficult accurately to remove surface reflection, cause to derive L_wWhen there are it is huge not Determine factor；In underwater section mensuration, in order to export the uplink spoke brightness for reaching the water surface, need through accurate data processing It obtains correct attenuation coefficient, when practical application, for the waters in height turbid water domain or vertical demixing, is difficult accurately to estimate The attenuation coefficient of propagation, therefore finally derive L_wWhen there is also huge uncertain factors；For floating on water mensuration, then need Uplink spoke brightness at 10-50cm below the water surface is derived into the uplink spoke brightness at 0cm below the just water surface.Moreover, right In underwater section mensuration and floating on water mensuration, it is necessary to by the refractive index and cross section reflectivity of hypothesis water come subjective It is derived with the uplink spoke brightness at 0cm below the just water surface from water spoke brightness L on ground_w, therefore, even if having accurately measured each Component, various degrees of uncertainty also still will affect L_wCalculating.

Currently, floating on water mensuration has been rarely mentioned, the above mensuration of the water surface and underwater section mensuration have generation The instrument of table.Such as, have using the representative observation instrument of the above mensuration of the water surface: Canadian Satlantic company HyperSAS apparent spectral observation device etc.；Have using the representative observation instrument of underwater section mensuration: marine optics buoy etc..

In short, in the prior art, no matter that observation instrument, as long as using three of the above measurement method, it all can not be quasi- It really measures from water spoke brightness, therefore, it is necessary to research and develop a kind of water body apparent spectral observation device based on new observation method, makes With direct measurement rather than it is derived by the method from water spoke brightness, with reduction method defect to the maximum extent, human error, is set Standby investment reduces the difficulty of operation and maintenance, and realizes higher observation accuracy.
