The absorptivity and transmittance of infrared radiation per unit wavelength corresponding to the Earth's atmosphere

When calculating the atmospheric absorptivity corresponding to the wavelength, first grid the picture of Radiation Transmitted by the Atmoshpere(https://doi.org/10.6084/m9.figshare.22081277.v3). In this case, the horizontal axis coordinate is an exponential function, and the function expression is a function with a base of 10 and an index of (n-26)/37; find the corresponding n value through the wavelength, and find the atmospheric absorbance corresponding to the unit wavelength in the figure.  Then get the dataset.
