On May 25, 2008, an aviation flight of L&K band airborne microwave radiometer was carried out in Linze grassland intensive observation area. This data can provide a basic ground data set for the development and verification of passive microwave remote sensing algorithm for retrieving soil moisture and soil salt.
The ground synchronous observation is carried out in the dense observation area of Linze grassland, including microwave synchronous sample band 1, sample band 2, sample band 3, sample band 4, sample band 5 and sample band 6. 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. The main surface type of sample belt 7 is sandy land, and the soil moisture content is very small. Therefore, supplementary measurement was carried out on June 2. Microwave synchronous sample belts 1, 2, 3 and 4 were used to obtain the real and imaginary parts of soil temperature, soil moisture, loss tangent, soil conductivity and soil complex dielectric constant by pogo portable soil sensor; Needle thermometer to obtain 0-5cm average soil temperature; The hand-held infrared thermometer obtains the surface radiation temperature for 3 times; Microwave synchronous belts 5 and 6 were used to measure the soil volume water content, electrical conductivity, real part of soil complex dielectric constant and soil temperature; The average soil temperature of 0-5cm was obtained by needle thermometer; The hand-held infrared thermometer obtains the surface radiation temperature three times. Microwave synchronous sample belt 7, using pogo portable soil sensor 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; Hand held infrared thermometer to obtain surface radiation temperature; And the ring knife soil is dried to obtain the weight water content, volume water content and soil bulk density.
This data set includes soil moisture and temperature measurement data tables for transects 1-6. 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.
On May 25, 2008, L& was conducted in Linze grassland intensive observation area; Aviation flight of K-band airborne microwave radiometer. This data can provide a basic ground data set for the development and verification of passive microwave remote sensing algorithm for retrieving soil moisture and soil salt.
