%X On July 4, 2008, an aviation flight of L & K band airborne microwave radiometer was carried out in Linze grassland intensive observation area. The ground synchronous observation is carried out in the new microwave synchronous sample belt newl1-newl12 in the intensive observation area of Linze grassland. The main observation variables are surface temperature, soil temperature and soil moisture. This data can provide a basic ground data set for the development and verification of active microwave remote sensing algorithm for retrieving soil moisture and soil salt. Each transect is arranged perpendicular to the route direction, and there are 5 sampling points on each transect. At each sampling point of each strip from newl1 to newl12, the soil is taken with a ring knife and dried to obtain the weight water content, volume water content and soil bulk density; Needle thermometer to obtain 0-5cm average soil temperature; The crown top temperature and surface temperature were obtained by hand-held infrared thermometer. This data set includes soil moisture and temperature data tables measured by four transects. One table includes four transect data. Surface temperature, canopy temperature, soil temperature and soil moisture are stored in one data table. See metadata "Heihe integrated remote sensing joint experiment: layout of quadrat transects in Linze grassland densified observation area" for the distribution information of quadrat transects
