%X On June 10, 2008, the surface synchronous observation of ALOS PALSAR data was carried out in sample a (reed land), sample B (saline alkali land), sample C (saline alkali land), sample D (alfalfa land) and sample e (barley land) in the intensive observation area of Linze grassland. Alos PALSAR data is FBS mode, HH polarization mode, and the transit time is about 23:39bjt. The main observation variable is 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. This data is observed at 120m × 120m，6Grid × Unfold in 6grid quadrat. The observation contents are as follows: the soil of sample a, sample B and sample C is taken with a ring knife and dried to obtain the weight water content, volume water content and soil bulk density; The needle thermometer obtains an average soil temperature of 0-5cm. Pogo portable soil sensors are used for sample D and sample e to obtain the real and imaginary parts of soil temperature, soil moisture, loss tangent, soil conductivity and soil complex dielectric constant; The needle thermometer obtains an average soil temperature of 0-5cm. This data set includes the excel table of soil moisture data of 5 quadrats. 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.
