Application of Remote Sensing Technology in Crop Chilling Injury Monitoring

Chilling injury monitoring is conducted by combination of EOS/MODIS satellite remote sensing data and surface meteorological observation data. Surface temperature is retrieved based on split window algorithm and others and the daily minimum temperature is calculated by combination of the surface meteorological observation data. In order to improve the monitoring precision, the remote sensing retrieval of surface temperature is tested. For the cloud covered area, precise temperature simulation is conducted by trend surface fitting, inverse distance weighted and other temperature small-grid prediction models on the basis of the temperature data of the surface encryption station, utilizing the geological information system. In addition, all-day temperature monitoring is realized by integration of refined temperature simulation and satellite remote sensing data.
