%X The infrared temperature system set up in the orchard at point ec17 can provide continuous ground observation data of orchard ground temperature for aerial flight data inversion of ground temperature products. Observation site: a large area and homogeneous orchard in Zhangye experimental field of Gansu Academy of Agricultural Sciences is selected as the observation point, which is located next to point ec17. The main observation vegetation is apple tree canopy. The coordinates of the observation point are: 38 ° 50'41.70 "n, 100 ° 22'11.40" E. Measuring instrument: the observation probe is a vertical s1-111 infrared temperature probe (newly purchased in 2012, the default ground emissivity is 1 when it leaves the factory, and blackbody calibration is not carried out during the test). Campell cr850 data collection automatic recording, fruit tree height 4m, crown width 4m × 4m, probe frame height 4.55m. It is located 4m southwest of ec17. Measurement time: the instrument has been observing normally since August 3, 2012. As of September 27, 2012, it has been observing continuously for 24 hours, recording data once a minute and outputting a group of data once a minute. Data content: surface temperature observation data (target)_ C_ AVG, surface emissivity and background temperature are not corrected), body temperature of si-111 instrument (SBT)_ C_ Avg）。 The data is finally stored as an independent text file for one day. The data naming method is: data format + observation point name + data sampling time + date + time. Dat. For detailed data header information, see the data header description in the data
