", "ds_ref_way": "", "ds_abstract": "On May 30, 2008, the aviation flight test of widas (wide angle infrared dual mode line / area array scanner) was carried out in the intensive observation area of Linze grassland. Widas is composed of 4 CCD cameras, 1 mid infrared thermal imager (AGEMA 550) and 1 thermal infrared thermal imager (S60). It can simultaneously obtain data of 5 angles of visible / near infrared (CCD) band, 7 angles of mid infrared band (MIR) and 7 angles of thermal infrared band (TIR). The ground synchronous observation variables are mainly surface temperature and shallow soil moisture. This data can provide a basic ground data set for the development and verification of active microwave remote sensing inversion algorithm of surface temperature and evapotranspiration.\n
\nThe survey 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. Synchronous quadrat includes 120m × 120m quadrat and 30m × There are two kinds of 30m encrypted small quadrats. When the surface temperature is measured synchronously, the hand-held infrared thermometer is used for continuous measurement in the east-west direction. See the schematic diagram in the data table for the travel route. Synchronous measurement of soil moisture: in quadrats a, B and C, 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; Pogo portable soil sensors were used to obtain soil temperature, soil moisture, loss tangent, soil conductivity, real and imaginary parts of soil complex dielectric in quadrats D and E; The needle thermometer obtains an average soil temperature of 0-5cm.\n
\nThis data set includes 5 excel tables for soil moisture measurement data of quadrats and 5 excel tables for surface temperature measurement. 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
