Atmospheric aerosol, which is an important parameter required for climate change studies, local air quality monitoring, global aerosol transport modeling, atmospheric correction and global aerosol characterization, decreases seriously regional air quality and may have a negative impact on public human health. Because aerosols had complex sources and the short lifetime, it is difficult to study the...
The study selects Heibei plain to be the research area, applies MODIS1B data with the spatial resolution of 1km and the actually tested soil moisture data, under the support of ENVI4.6 technology platform, make use of interactive IDL language programming to uniformly process the remote sensing image, to obtain various land surface parameters required by the apparent thermal inertia model and vegetation...
Vegetation Moisture Content Monitoring originated from the needs of forest fire assessment. On the one hand, the water content of vegetation affects the forest ignition point; the other hand, it affects the burning rate if the forest is on fire. This study is based on the above reasons, using the GVMI exponential model, inversion of vegetation water content information in Daxing'anling region, Preliminary...
Vegetation indices of NDVI, VIgreen, VARI, EVI were used to establish the one-dimensional linear inversion model combing with field vegetation canopy reflectance and canopy chlorophyll content. By comparison of the results, the model accuracy of NDVI is much higher. But the model established by the 4 indexes has the highest accuracy with the correlation coefficient of 0.503 and root mean square error...
