HiWATER: Observation Dataset of Spectral Reflectance in the lower reaches of the Heihe River Basin
Alt title:
  1. Abstract

    Spectral reflectance observation was carried out for the typical underlying surface and black and white cloth in the low reaches of the Heihe River Basin during the aviation flight experiment in 2014, which will provide basic data set for the preprocessing of the flight data.

    1. Observation Instrument

    PRS-3500 portable spectrometer, with the spectral range is 350-2500 nm, and the reference board.

    2. Samples and observation methods

    The samples including the black and white cloth, the cantaloupe, the Tamarix chinensis, the Populus euphratica, the reeds, the weeds, the Karelinia caspica, the sandy soil, the gobi, the Sophora alopecuroides and so on.

    Reflectance of the reference board was measure vertically for once and then objective reflectance were measured for five times for each observation objective.

    3. Observation time

    The typical underlying surface vegetation observation was on days of 24 July, 27 July, 31 July, 2014. The black and white cloth simultaneous observation was on 29 July, 2014.

    4. Data storage

    The observation recorded data were stored in excel and the original spectral data were stored in *.sed files derived from the spectrometer, which can be opened by the matched software of the spectrometer or by a txt.
