On July 8, 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 dense observation area of Linze grassland, including microwave synchronous sample band L1, sample band L2, sample band L3, sample band L4, sample band L5 and sample band L6. 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 sample strip is arranged perpendicular to the route direction. There are 25 sampling points on each sample strip, and the spacing of each sampling point is 100m. At each sampling point of each strip, 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 in 6 transects. Surface 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.
