河北小麦和玉米日尺度反射率数据集

该数据集是在河北省保定市定兴县固城镇气象科学研究站内，利用具有较高光谱分辨率的QE65PRO光谱仪测量的日尺度上的小麦和玉米的反射率数据集，测量时间为北京时间8点-17点。小麦观测日期为2018年5月1日和2018年5月14日，玉米观测日期为2018年7月25和8月3日。测量内容包括光谱反射率、地物名称、所属类别、观测日期、观测时间、经度、纬度、数据来源、观测地点名称、县区编号、波谱仪器型号、起始波长、终止波长、光谱分辨率、视场角、植被品种、植被近景彩照等。由于QE光谱仪的光谱分辨率较高，它测量的光谱数据同时可以用来提取太阳诱导叶绿素荧光（SIF）。该数据集共有波谱数据208条。

This dataset is a daily-scale reflectance dataset of wheat and corn measured using a high spectral resolution QE65PRO spectrometer at the Meteorological Scientific Research Station in Gucheng Town, Dingxing County, Baoding City, Hebei Province. Measurements were conducted between 8:00 and 17:00 Beijing Time. Wheat observations were carried out on May 1 and May 14, 2018, while corn observations were performed on July 25 and August 3, 2018. The measured contents include spectral reflectance, surface feature name, category, observation date, observation time, longitude, latitude, data source, observation site name, county code, spectrometer model, starting wavelength, ending wavelength, spectral resolution, field of view (FOV), vegetation variety, and close-range color photographs of vegetation, among others. Owing to the high spectral resolution of the QE spectrometer, the acquired spectral data can also be utilized to extract solar-induced chlorophyll fluorescence (SIF). This dataset contains a total of 208 spectral data records.
