Spectrum and arsenic content of soil samples in Honghu and Daye, Hubei Province, China

For the samples from Honghu, the spectral reflectance was measured by SVC HR-1024 field spectrometer. The number of wavelengths in the spectrum is 990.The resolution of 350-1000 nm, 1000-1900 nm and 1900-2500 nm are 1.5 nm, 3.8 nm and 2.5 nm respectively.The spectral reflectance of the soil sample from Daye was measured by ASD FieldSpec3 field spectrometer with spectral resolution of 1nm and wavelength range of 350-2500 nm. The number of wavelengths is 2151.To avoid the influence of edge noise, the wavelengths of 350-399nm and 2400-2500nm have been removed

The first column of values is the arsenic content in the soil sample.
