On June 27, 2008, the ground synchronous observation of ALOS PALSAR data was carried out in sample a (reed land), sample B (saline alkali land), sample D (alfalfa land) and sample e (barley land) in the intensive observation area of Linze grassland. Alos PALSAR data is in FBD mode, HH / HV polarization combination mode, and the transit time is about 23:41bjt. 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 and sample B 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; 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; Needle thermometer to obtain 0-5cm average soil temperature; The weight water content, volume water content and soil bulk density are obtained by drying the soil with a ring knife.
This data set consists of Excel tables of soil moisture measurement data of 4 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.
