AB  - This data set is the soil moisture data set of Yingke oasis and huazhaizi desert intensive observation area. Measuring instruments: ring knife and TDR. Dig out 1m soil profile in desert, orchard and other places, and measure soil moisture at 0cm, 20cm, 40cm and 1m. TDR in remote sensing has two probes with different lengths, 12cm and 20cm respectively. Therefore, 12cm and 20cm probes were used to measure the bare soil and under film soil in corn quadrat, inter ridge soil and under wheat soil in wheat quadrat. Measurement time and content: Discontinuous observation time: 2008-05-202008-05-282008-05-302008-05-312008-06-042008-06-162008-06-192008-06-292008-07-072008-07-112008-7-18. With various flights and satellite transit, the soil moisture of Yingke oasis sample plot (including another synchronous test in a rou grassland) was measured simultaneously. Data unit: the unit measured by ring knife is the weight percentage of aluminum box wet soil weight - aluminum box dry soil weight, and the unit measured by pogo is the volume percentage.（ 1) On May 20, 2008, TM passed through the dense observation area of Yingke oasis. In cooperation with the synchronous measurement of soil moisture, sample plots 1, 4 and 5 in the corn field of Yingke oasis were measured.（ 2) On May 28, 2008, aster and MODIS were synchronized, and the survey site was Yingke oasis sample plot.（ 3) On May 30, 2008, the airborne wide-angle infrared dual-mode line / area array scanner (widas) was synchronized on the ground, and the measurement site was at Yingke oasis.（ 4) On May 31, 2008, the airborne wide-angle infrared dual-mode line / area array scanner (widas) was synchronized on the ground, and the measurement location was in Arao grassland.（ 5) The flight synchronization of imaging spectrometer omis-ii was conducted on June 4, 2008, and the measurement location was Yingke oasis sample plot.（ 6) The flight synchronization of imaging spectrometer omis-ii was conducted on June 16, 2008, and the measure
