%X On July 7, 2008, the ground synchronous observation test for widas (wide angle infrared dual mode line / area array scanner) aviation flight was carried out in arxo quadrat 1, arxo quadrat 2 and arxo quadrat 3. The observation items include surface feature spectrum, vegetation photosynthetic data and surface infrared temperature. A rou sample 1, a rou sample 2 and a rou sample 3 are 4grid × 4grid, 3 m per grid × 30m。 Observation instrument: ASD FieldSpec spectrometer of Beijing Normal University, 350 ~ 2500 nm. Reference plate information: 20% reference plate. Observation targets: Stellera chamaejasme, Oxytropis and herbage. Data storage: data includes original data and partially preprocessed data. The original data is the binary file directly generated by the spectrometer, which can be opened with viewspecpro software. See the daily observation records in the data file for detailed observation records; The reflectance data obtained by preprocessing is in text format. Vegetation photosynthetic data measuring instrument: Li-6400. Measured objects: Stellera chamaejasme, Oxytropis and herbage. Operation specification: please refer to the joint test operation specification for the operation process. Data storage: process data and save it in Excel. Surface temperature measurement method: hand held infrared thermometer. Number of measuring points: 25 measuring positions: 30m × Measured on the corner of 30m grid. Record information: sampling time, infrared temperature repeated for 3 times, description of surface coverage type. This dataset includes:（ 1) Spectral folders of Stellera chamaejasme with different coverage; 60% and 65% coverage spectral file data and spectral measurement record sheet; Wolf venom photo folder（ 2) Photosynthetic data folder: including photosynthetic data tables (Oxytropis, Stellera chamaejasme and Stipa) and photosynthetic data header description files（ 3) Aircraft synchronous infrared temperature data table.（ 4) Widas mosaic image with resolution
