FIG. 4 is a correction method for correcting an error of a measurement temperature caused by albedo according to an embodiment of the present invention, and FIG. 5 is a graph illustrating a correlation of temperature of an albedo size according to an embodiment of the present invention Graph.

As shown in Figs. 1 to 3, an apparatus for measuring a gaseous temperature measurement error caused by albedo is provided. The apparatus includes a device body 100, a temperature measurement unit 200, a cutoff unit 300, (400).

The apparatus main body 100 may include a temperature measurement unit 200, a cutoff unit 300, and a fixed unit 400. [

 The apparatus main body 100 may be an ABS plastic resin whose material is synthetic resin.

That is, the material of the apparatus main body 100 is a plastic material which is lightweight, durable, has good heat insulation, and is an example of an ABS plastic resin.

ABS resin (ABS resin) is composed of acrylonitrile, butadiene, styrene, and filler. Their composition changes greatly.

Plating (plating) is also possible, and the use of the metalized plastic is spreading.

The material of the apparatus main body 100 is not limited to the ABS plastic resin, and the best one among various kinds of synthetic resins may be selected depending on the situation.

The temperature measuring unit 200 can be installed in a part of the apparatus main body 100 to measure the radiation temperature of the surface of the apparatus.

The temperature measuring unit 200 is provided with a plurality of temperature sensors and can measure the error of the gaseous phase temperature occurring in the albedo by the surface radiation through each temperature sensor.

Here, albedo is a numerical value indicating the degree of reflection of light, which is also referred to as reflectance. In general, light is scattered mainly in the atmosphere, so the planet's albedo, which has an atmosphere, is much larger than an airless object.

Specifically, albedo is also called reflectance. For example, light incident from the sun is partially absorbed by the atmosphere or surface of the planet, but the rest travels in several directions through one or more scatterings or reflections. In this case, the total amount of light is divided by the intensity of incident light.

In general, light is absorbed mainly in solids such as the ground, but mainly scattered in the atmosphere, so the albedo of the planet with the atmosphere is much larger than the airless object. For example, the Moon with no atmosphere is 0.12 and Mercury with 0.142, while the atmosphere with the atmosphere is 0.367 and Venus with 0.67 (which is bigger than Earth because of the large amount of carbon dioxide in the atmosphere).

The temperature measuring unit 200 may include a white temperature sensor 210, a black temperature sensor 220 and a sensor lead line 230.

The white temperature sensor 210 can be fixed by the fixed unit 400 to measure the temperature radiated from the surface.

The surface of the black temperature sensor 220 can be graphitically coated.

The white temperature sensor 210 and the black temperature sensor 220 may be formed in a conical shape so that droplets generated by moisture may flow downward.

Specifically, the white temperature sensor 210 and the black temperature sensor 220 may be any type of thermoelectric or resistive type.

The thickness, length, material and shape of the sensor unit exposed on the surface of the sensor unit should be the same. The white temperature sensor 210 may be a polished stainless steel metal, and the black temperature sensor 220 may be a white temperature sensor 210 may be coated with black graphite on the same sensor surface.

The white temperature sensor 210 means a sensor having a general metal surface, and the black temperature sensor 220 means a graphite coated sensor.

The white temperature sensor 210 and the black temperature sensor 220 may be any of industrial resistance thermometers, thermistors, and thermocouples. The thickness may be within a range of 2 mm to 10 mm. The length of the sensor support plate 410 exposed to the ground surface may be Preferably about 20 to 25 times.

The coating area of the black temperature sensor 220 may be 3 to 5 times the diameter of the sensor.

The sensor lead wire 230 is connected to the white temperature sensor 210 and the black temperature sensor 220 and can connect the outside to the white temperature sensor 210 and the black temperature sensor 220 through the fixing unit 400 .

The shielding unit 300 may be formed in a shape covering the upper part of the temperature measurement unit 200 while forming a part of the apparatus main body 100 to protect the temperature measurement unit 200 from outside air.

The blocking unit 300 may include a blocking cap 310 and a cap support 320.

The shutoff cap 310 can protect the temperature measurement unit 200 from external air by covering the upper part of the temperature measurement unit 200 and a part of the fixed unit 400.

The shutoff cap 310 may be coated with a white color on the outside and a black color on the inside.

That is, the upper surface of the shutoff cap 310 may be coated with a low emissivity white paint, and the side surface may be opened to provide air circulation therein. The shape can be a conical shape that allows rain, snow, and pollutants to flow naturally. The underside can be designed to absorb the surrounding radiation by applying a high emissivity graphite coating.

The cap support 320 is installed at a lower portion of the shutoff cap 310 and may be coupled to the fixed unit 400 to provide a support force to the shutoff cap 310.

The fixing unit 400 is fabricated in a state of being coupled to the temperature measuring unit 200 and the breaking unit 300 while forming a part of the apparatus main body 100 and supports the temperature measuring unit 200 and the breaking unit 300 It is possible to fix the temperature measuring unit 200 and the shielding unit 300 in a horizontal or vertical state on the ground.

The fixing unit 400 may include a sensor supporting plate 410 and a fixing support 420.

Specifically, the diameter of the sensor support plate 410 may be 10 times or more the thickness of the temperature sensor. The shape of the sensor support plate 410 is preferably a cone shape slightly bent to the ground. The reason is that the water drops due to the moisture that may be generated can flow naturally downward.

The upper and lower surfaces of the sensor support plate 410 are coated with a low emittance reflection coating so that the energy radiated from the bottom surface does not heat the sensor support plate 400.

The sensor supporting plate 410 is fixed to the fixing supporter 420 and connects the temperature measuring unit 200 and the outside to form a part of the apparatus main body 100 to provide a supporting force for supporting the apparatus main body 100 horizontally or vertically can do.

The temperature measuring apparatus 10 of the present invention may further include a sensor insulation 500 and a protection shield 600.

The protection shield 600 is coupled downward from below the fixed unit 400 while covering the temperature measurement unit 200 to protect the temperature sensors of the temperature measurement unit 200 from rain or wind.

The protection shield 600 may be coated with a white color on the outside and a black color on the inside.

The anti-wind prevention shield 600 is coated on the outside of the sensor support plate 410 with a white coating and a black coating on the inside thereof so that strong wind or rain does not directly contact the white temperature sensor 210 and the black temperature sensor 220 Can be installed.

Specifically, the temperature measuring apparatus 10 of the present invention is provided with a coated white temperature sensor 210 and a black temperature sensor 220 facing the ground so that their surface emissivity is different from each other.

The degree of temperature rise between the white temperature sensor 210 and the black temperature sensor 220 is different due to the albedo effect copied by the surface or the periphery.

The present invention relates to a technique and an apparatus for correcting an error of temperature measurement caused by albedo due to surface radiation by measuring the relative temperature difference between the white temperature sensor 210 and the black temperature sensor 220. [

The temperature difference of the white and black temperature sensors,

Lt; / RTI > temperature,

Represents the temperature of the white temperature sensor.
13. The method of claim 12,
Wherein the actual land surface temperature is calculated according to the following equation (3) in the step of calculating the meteorological observation temperature.
Equation 3
T =

-

In Equation (3), T is the actual surface temperature,

The temperature of the white temperature sensor,

Represents a temperature correction value.
