AB  - This data set is the discontinuous observation data of albedo from May 20, 2008 to July 14, 2008 in Yingke oasis intensive observation area, huazhaizi desert intensive observation area, Linze station intensive observation area, biandukou intensive observation area and Zhangye intensive observation area. The albedo measurement was synchronized with the flight of airborne infrared wide-angle dual-mode line / area array scanner (widas), imaging spectrometer omis-ii, and spaceborne TM, aster, Hyperion and Chris. Measurement content: (1) Yingke oasis and huazhaizi desert intensive observation area. The albedo was measured in Yingke oasis station corn plot, wheat plot and huazhaizi desert station plot 2 before and after. ① Yingke oasis station corn field: 2008-05-28, 2008-05-30, 2008-06-03, 2008-06-16, 2008-06-20, 2008-06-27, 2008-06-29, 2008-07-11, 2008-07-14; ② Yingke wheat plot: 2008-05-202008-05-292008-06-012008-06-042008-06-062008-06-092008-06-152008-06-242008-07-072008-07-14; ③ Sample plot 2 of huazhaizi desert station: 2008-06-142008-06-222008-06-30; Flax: June 23, 2008(2) Intensive observation area of Linze station: ① Linze corn: May 25, 2008; ② Desert and alfalfa: May 24, 2008 (3) Biandukou intensive observation area: rape grass and barley: June 24, 2008; Barley: July 6, 2008(4) Zhangye intensive observation area: Jindu roof and grassland in the city: May 27, 2008 Measuring instruments: No. 1 short wave radiometer (cmp3-060580) and No. 2 short wave radiometer (cmp3-060584) of Remote Sensing Institute. The voltage measuring instrument is unit ut58 digital multimeter. Data processing: the voltage values in the upper table and the voltage values in the lower table including the shortwave meter are used for calculation, and then converted into albedo data through the sensitivity coefficient of the table. The original data is paper form, and the digital input is excel form Observation to be specially noted: in the later stage of crop growth, the height of corn is more
