Abstract :
HJ-1/IRS is an infrared camera boarded on HJ-1B with four bands that includes 0.75~1.10μm, 1.55~1.75μm, 3.50~3.90μm and 10.5~12.5μm. It has a higher spatial resolution with 150m for the first three bands and 300m for the last thermal band. This paper first did research on the method of hot abnormal points by HJ-1/IRS camera, brought out the retrieval algorithm for detecting fire straw burning and straw burning for HJ-1/IRS, then did some test work to verify the work by comparing the result with that of MODIS, finally the paper taking use of AOD (aerosol optical depth) data and NO2 data from Aura/OMI to do some analysis work to research on the effect of straw burning to the air quality. The results showed that Straw burning can lead to bad air condition.
