Reflectance spectra of agricultural field conditions supporting remote sensing evaluation of non-photosynthetic vegetation cover

This data release contains spectra used to evaluate narrow-band shortwave infrared indices suitable for measurement of non-photosynthetic vegetation (NPV). The original data were collected using a proximal Analytical Spectral Devices(ASD) FieldSpecPro spectroradiometer, and are also provided in various states of processing, all of which is described in the manuscript referenced below. Items 1-9 include spectra, items 10-12 include statistical descriptions of correlation goodness of fit between derived indices and fractional NPV cover, and item 13 contains estimated Landsat Next sensor radiometric properties. Item 14 includes spectra added to version 1.1 of this data release which corresponds to a closely related 2022 research effort and publication. The data provided here, and the processes used to calculate and analyze them, are further discussed in Hively, W.D., Lamb, B.T., Daughtry, C.S.T., Serbin, G., Dennison, P., Kokaly, R.F., Wu, Z., and Masek, J., 2021. Evaluation of SWIR recommended crop residue bands for the Landsat Next mission. Remote Sensing, 13, 18, 3718. https://doi.org/10.3390/rs13183718. Additional spectra processing techniques for item 14 are discussed in an additional publication by Lamb, B.T., Dennison, P., Hively, W.D., Kokaly, R.F., Serbin, G., Wu, Z., Dabney, P., Masek, J.G., Campbell, M., Daughtry, C.S.T. 2022.
