In the morning, the sensors carried on the frozen surface are LK band airborne microwave radiometer (flight time 8:06 ~ 11:17bjt), and in the noon, the sensors carried on the molten soil are L band airborne microwave radiometer and thermal imager (flight time 12:48 ~ 16:35bjt). The ground synchronous observation is carried out in arxoid belt 2, arxoid belt 3, arxoid belt 4, arxoid belt 5 and arxoid belt 6. Each sample belt is oriented from north to south, and the spacing of sampling points on each belt is about 100m. In the morning, the ground moves from north to South at the same time, and in the afternoon, it moves from south to North at the same time. At each sampling point of flexible sample belt 2, flexible sample belt 4 and flexible sample belt 6, pogo portable soil moisture sensor is used to obtain the real and imaginary parts of soil temperature, soil volume water content, loss tangent, soil conductivity and soil complex dielectric constant; Needle thermometer to obtain 0-5cm average soil temperature; The hand-held infrared thermometer obtains the surface radiation temperature for 3 times; The soil is taken with a 100cm ^ 3 ring knife and dried to obtain the weight water content, soil bulk density and volume water content. In the flexible sample zone 3, the ml2x soil moisture rapid meter was used to obtain the soil volume water content; Needle thermometer to obtain 0-5cm average soil temperature; The hand-held infrared thermometer obtains the surface radiation temperature for 3 times; The soil is taken with a 100cm ^ 3 ring knife and dried to obtain the weight water content, soil bulk density and volume water content. In a flexible sample zone 5, the real parts of soil volume water content, electrical conductivity, soil temperature and soil complex dielectric constant were measured by wet soil moisture meter; Needle thermometer to obtain 0-5cm average DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/61b2a222-a632-4147-8bb3-611794731cbd ER -
